Working dogs cooperate among one another by generalised reciprocity
Authors: Gfrerer Nastassja , Taborsky Michael 
Published: March 2017

AbstractCooperation by generalised reciprocity implies that individuals apply the decision rule “help anyone if helped by someone”. This mechanism has been shown to generate evolutionarily stable levels of cooperation, but as yet it is unclear how widely this cooperation mechanism is applied among animals. Dogs (Canis familiaris) are highly social animals with considerable cognitive potential and the ability to differentiate between individual social partners. But although dogs can solve complex problems, they may use simple rules for behavioural decisions. Here we show that dogs trained in an instrumental cooperative task to provide food to a social partner help conspecifics more often after receiving help from a dog before. Remarkably, in so doing they show no distinction between partners that had helped them before and completely unfamiliar conspecifics. Apparently, dogs use the simple decision rule characterizing generalised reciprocity, although they are probably capable of using the more complex decision rule of direct reciprocity: “help someone who has helped you”. However, generalized reciprocity involves lower information processing costs and is therefore a cheaper cooperation strategy. Our results imply that generalised reciprocity might be applied more commonly than direct reciprocity also in other mutually cooperating animals.
Effect of Foam on Liquid Phase Mobility in Porous Media
Authors: Eftekhari A. A. , Farajzadeh R. 
Published: March 2017

AbstractWe investigate the validity of the assumption that foam in porous media reduces the mobility of gas phase only and does not impact the liquid-phase mobility. The foam is generated by simultaneous injection of nitrogen gas and a surfactant solution into sandstone cores and its strength is varied by changing surfactant type and concentration. We find, indeed, that the effect of foam on liquid-phase mobility is not pronounced and can be ignored. Our new experimental results and analyses resolve apparent discrepancies in the literature. Previously, some researchers erroneously applied relative permeability relationships measured at small to moderate capillary numbers to foam floods at large capillary number. Our results indicate that the water relative permeability in the absence of surfactant should be measured with the capillary pressure ranging up to values reached during the foam floods. This requires conducting a steady-state gas/water core flood with capillary numbers similar to that of foam floods or measuring the water relative-permeability curve using a centrifuge.

Published: March 2017

AbstractThis study aimed to determine the major food groups contributing to dietary glycaemic load (GL). Plausible food intake data collected using a multiple-pass 24 hour recall from a weighted sample of 6326 adult respondents (52% male) of the 2011–2012 Australian Health Survey dataset (AHS) were analysed. The GI of foods was estimated based on a previously published step-wise method. Descriptive statistics were calculated for dietary glycaemic index (GI), GL and contribution to GL by major food groups, stratified by age and sex. Trends across age groups were assessed using linear regression. Pearson’s χ2 was used to test for differences between age groups for categorical demographics variables. The mean (SD) dietary GI and GL was 54 (7) and 135 (59) respectively and the top 3 contributors to dietary GL were breads (14.4%), cereal-based dishes (10.3%) and breakfast cereals (ready to eat) (6.6%). There were small but significant differences in the GL contribution pattern between the sexes. The findings indicate that the average dietary GI of Australian adults is similar to that of other population groups, with a large proportion of starchy and energy-dense nutrient-poor foods that contribute to a high GL.

AbstractPancreatic cancer cells express high levels of MUC1, MUC4 and MUC16 mRNAs that encode membrane-bound mucins. These mRNAs share unusual features such as a long half-life. However, it remains unknown how mucin mRNA stability is regulated. Galectin-3 (Gal-3) is an endogenous lectin playing important biological functions in epithelial cells. Gal-3 is encoded by LGALS3 which is up-regulated in pancreatic cancer. Despite the absence of a RNA-recognition motif, Gal-3 interacts indirectly with pre-mRNAs in the nucleus and promotes constitutive splicing. However a broader role of Gal-3 in mRNA fate is unexplored. We report herein that Gal-3 increases MUC4 mRNA stability through an intermediate, hnRNP-L which binds to a conserved CA repeat element in the 3′UTR in a Gal-3 dependent manner and also controls Muc4 mRNA levels in epithelial tissues of Gal3−/− mice. Gal-3 interacts with hnRNP-L in the cytoplasm, especially during cell mitosis, but only partly associates with protein markers of P-Bodies or Stress Granules. By RNA-IP plus RNA-seq analysis and imaging, we demonstrate that Gal-3 binds to mature spliced MUC4 mRNA in the perinuclear region, probably in hnRNP-L-containing RNA granules. Our findings highlight a new role for Gal-3 as a non-classic RNA-binding protein that regulates MUC4 mRNA post-transcriptionally.
Pricing the urban cooling benefits of solar panel deployment in Sydney, Australia

Published: March 2017

AbstractCities import energy, which in combination with their typically high solar absorption and low moisture availability generates the urban heat island effect (UHI). The UHI, combined with human-induced warming, makes our densely populated cities particularly vulnerable to climate change. We examine the utility of solar photovoltaic (PV) system deployment on urban rooftops to reduce the UHI, and we price one potential value of this impact. The installation of PV systems over Sydney, Australia reduces summer maximum temperatures by up to 1 °C because the need to import energy is offset by local generation. This offset has a direct environmental benefit, cooling local maximum temperatures, but also a direct economic value in the energy generated. The indirect benefit associated with the temperature changes is between net AUD$230,000 and $3,380,000 depending on the intensity of PV systems deployment. Therefore, even very large PV installations will not offset global warming, but could generate enough energy to negate the need to import energy, and thereby reduce air temperatures. The energy produced, and the benefits of cooling beyond local PV installation sites, would reduce the vulnerability of urban populations and infrastructure to temperature extremes.

Published: March 2017

AbstractSolar cells based on epitaxial silicon layers as the absorber attract increasing attention because of the potential cost reduction. In this work, we studied the influence of the deposition rate on the structural properties of epitaxial silicon layers produced by plasma-enhanced chemical vapor deposition (epi-PECVD) using silane as a precursor and hydrogen as a carrier gas. We found that the crystalline quality of epi-PECVD layers depends on their thickness and deposition rate. Moreover, increasing the deposition rate may lead to epitaxy breakdown. In that case, we observe the formation of embedded amorphous silicon cones in the epi-PECVD layer. To explain this phenomenon, we develop a model based on the coupling of hydrogen and built-in strain. By optimizing the deposition conditions to avoid epitaxy breakdown, including substrate temperatures and plasma potential, we have been able to synthesize epi-PECVD layers up to a deposition rate of 8.3 Å/s. In such case, we found that the incorporation of hydrogen in the hydrogenated crystalline silicon can reach 4 at. % at a substrate temperature of 350 °C.

Published: March 2017

Background Massive transfusion protocols (MTPs) have been examined in trauma. The exact ratio of packed red blood cells (PRBC) to other blood replacement components in hemostatic resuscitation in obstetrics has not been well defined.
Objective The objective of this study was to evaluate hemostatic resuscitation in peripartum hysterectomy comparing pre- and postinstitution of a MTP.
Study Design We conducted a retrospective, descriptive study of women undergoing peripartum hysterectomies from January 2002 to January 2015 who received ≥ 4 units of PRBC. Individuals were grouped into either a pre-MTP institution group or a post-MTP institution group. The post-MTP group was subdivided into those who had the protocol activated (MTP) versus not activated (no MTP). Primary outcomes were estimated blood loss (EBL) and need for blood product replacement. The secondary outcome was a composite of maternal morbidity, including need for mechanical ventilation, venous thromboembolism, pulmonary edema, acute kidney injury, and postpartum infection. A Mann–Whitney U test was used to compare continuous variables, and a chi-squared test was used for categorical variables with significance of p < 0.05.
Results Of the 165 women who had a peripartum hysterectomy during the study period, 62 received four units or more of PRBC. No significant differences were noted in EBL or blood product replacement between the pre-MTP (n = 39) and post-MTP (n = 23) groups. Similarly, the MTP (n = 6) and no MTP (n = 17) subgroups showed no significant difference between EBL and overall blood product replacement. Significant differences were seen in transfusion of individual blood products, such as fresh frozen plasma (FFP) (MTP = 4, no MTP = 2; p = 0.02) and platelets (plts) (MTP = 6, no MTP = 0; p = 0.03). The use of high ratio replacement therapy for both plasma and plts was more common in the MTP group (FFP/PRBC ratio [MTP = 0.5, no MTP = 0.3; p = 0.02]; plts/PRBC ratio [MTP = 0.7, no MTP = 0; p = 0.03]). There were no differences in the secondary outcome between pre- and post-MTP or MTP and no MTP.
Conclusion Initiation of the MTP did result in an increase in transfusion of FFP and plts intraoperatively. At our institution, the MTP is underutilized, but it appears that providers are more cognizant of the use of high transfusion ratios.

Abstract
Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP. In the present study, we investigated the clinical outcomes of patients with FAP diagnosed with gastric neoplasms.
Patients and methods We enrolled 80 patients with FAP who underwent esophagogastroduodenoscopy from October 1997 to December 2011. We investigated patient characteristics, endoscopic findings of gastric lesions, treatment outcomes, and long-term courses.
Results Fundic gland polyposis was observed in 51 patients (64 %) and gastric neoplasms in 22 patients (28 %), including 20 with non-invasive and 2 with invasive neoplasm. Of the 26 neoplasms, 11 were treated by endoscopic resection (ER) and 4 by surgical resection. Metachronous gastric neoplasms were observed in 7 patients (15 lesions) and treated by ER, except for in 1 patient. No patients died of gastric lesions during a median follow-up period of 6.5 years (range, 0 – 14).
Conclusion Because gastric lesions including gastric cancers in patients with FAP did not cause any deaths, they can be considered to have favorable prognoses. Early detection of gastric neoplasms through an appropriate follow-up interval may have contributed to these good outcomes.

Einflussfaktoren
Authors: Ehlert Andree 
Published: March 2017

Zusammenfassung
Ziel Die Studie analysiert aufgabenbezogene Kooperationen niedergelassener Ärzte wie u. a. Versorgungsprogramme,
Fachnetzwerke, Qualitätszirkel oder Fallkonferenzen. Ein multivariates statistisches Modell quantifiziert mögliche
Einflussfaktoren auf spezifische Kooperationsformen. Dadurch können Anhaltspunkte für das Zustandekommen ärztlicher Kooperationen
identifiziert werden.
Methodik Im August und September 2014 wurden in einer Zufallsstichprobe 6 000 niedergelassener Ärzte (im Folgenden immer
m/w) aus den Bundesländern Bremen, Hamburg, Niedersachsen und Schleswig-Holstein 504 voll strukturierte Telefoninterviews auf
Basis eines neu entwickelten Fragebogens durchgeführt.
Ergebnisse Mehr als die Hälfte der befragten Ärzte ist in Qualitätszirkel, Fallkonferenzen oder Fachnetze eingebunden. Die
Kooperationsneigung älterer Praxisinhaber ist geringer. Signifikante Stadt-Land-Unterschiede existieren im Allgemeinen nicht. Die
Anzahl der in der Praxis tätigen Ärzte hat generell keinen Einfluss auf das Kooperationsniveau, während die Mitarbeit in Verbänden
einen positiven Einfluss hat.
Schlussfolgerung Die Beteiligung an aufgabenbezogenen Kooperationsformen zeigt, dass der ambulante Sektor weniger
zersplittert ist als oft angenommen. Der Einfluss spezifischer Praxismerkmale auf Kooperationen liefert systematische Ansatzpunkte
für politische Maßnahmen. Es lassen sich u. a. altersspezifische Ansprachen der Ärzte sowie Forschungsbedarf über die Rolle der
Berufsverbände ableiten.
New Curcumin-Loaded Chitosan Nanocapsules: In Vivo Evaluation
Authors: Marin Edgar , Briceño Maria , Torres Alicia , Caballero-George Catherina 
Published: March 2017

AbstractThe medicinal applications of curcumin, the major component of Curcuma longa, are limited by its poor solubility and low oral bioavailability. In order to overcome this limitation, a method to produce nanocapsules of chitosan loaded with curcumin was developed. Three different molecular weight and deacetylation degree chitosan polymers were used in the formulation in order to prepare curcumin-loaded nanocapsules (mass ratio 1 : 1.4). The best results were achieved using chitosan-Bi with a molecular weight of 710 000 Da. A bimodal distribution was observed in samples; moreover, chitosan-Bi produced the lowest particle size (197 nm). The entrapment efficacy of all chitosan nanocapsules produced reached values between 75 and 92 %. Their rate of drug release at different pH levels (2.0 and 7.4) showed a fast onset of curcumin release. Swiss mice were used to determine oral and total bioavailability of the new curcumin-loaded nanocapsules. Remarkably, the bioavailability of curcumin nanoformulated increased 9-fold compared with no formulated curcumin. These nanocapsules have the ability to cross the blood-brain barrier, and its production is an easy to scale-up procedure using nontoxic materials.
Designing the Rashba spin texture by adsorption of inorganic molecules
Authors: Friedrich Rico , Caciuc Vasile , Bihlmayer Gustav , Atodiresei Nicolae , Blügel Stefan 
Published: March 2017

Abstract
Using the physisorption and chemisorption of inorganic molecules on BiAg2/Ag(111) we demonstrate from first principles that the spin–orbit splitting and the spin direction of surface Rashba-split states can be manipulated selectively. Although NH3 is physisorbed, it nevertheless leads to a slight enhancement of the outward buckling of the surface Bi that increases the magnitude of the Rashba splitting. On the other hand, the weakly chemisorbed BH3 determines a strong inward relaxation of the surface Bi such that the occupied Rashba state shifts into Ag bulk states while a new unoccupied one is induced. Importantly, for the BH3–BiAg2/Ag(111) system the size of the out-of-plane spin polarization is significantly larger than the in-plane one at variance with the clean surface case.
Micro-Scale Transport Processes for Advanced Healthcare and Point of Care Diagnostics

ABSTRACTRecent outbreaks like Zika and Ebola highlights the challenges associated with pathogen diagnostics in the developing world. With the outbreak in Africa, and isolated cases on other continents, the need for an affordable, rapid and portable diagnostic solution has been repeatedly stressed and is one of the most critical issues confronting global health. Unfortunately, the current conventional PCR instrumentation needed to perform gold standard DNA-based diagnostic tests is bulky, slow, and expensive, making it unsuitable for resource-limited settings in developing countries where dedicated laboratory facilities are not available. Advances in micro-fluidics and smartphone based technology has paved way for novel implementations of traditional molecular diagnostic techniques. We present a series of advances in molecular diagnostic techniques by harnessing convective flow to actuate biochemical reactions.
Maintaining their genetic distance; limited gene flow between widely hybridising species ofGeumwith contrasting mating systems

Published: March 2017

AbstractMating system transition from outcrossing to selfing frequently gives rise to sister lineages with contrasting outcrossing rates. The evolutionary fate of such lineages depends on the extent to which they exchange genes. We measured gene flow between outcrossingGeum rivaleand selfingG. urbanum, two sister species derived by mating system transition, which frequently hybridise. A draft genome was generated forG. urbanumand used to develop dd-RAD data scorable in both species. Coalescent analysis of RAD data from allopatric populations indicated that the two species diverged 2-3 Mya, and that long term gene flow between them has been very low (M=0.04).G. rivaleshowed greater genetic diversity in sympatry than allopatry, but genetic divergence between species was no lower in sympatry than allopatry, providing little evidence for recent introgression. Clustering of genotypes revealed that, apart from four early generation hybrids, individuals in sympatric populations fell into two genetically distinct groups with <1% admixture that corresponded exactly to their morphological species classification. Although our data suggest limited gene flow, we observed joint segregation of two putatively introgressed SNPs inG. urbanumpopulations that was associated with significant morphological variation; this provides tentative evidence for rare introduction of novel genetic diversity by interspecific gene flow. Our results indicate that despite frequent hybridisation, genetic exchange betweenG. rivaleandG. urbanumhas been very limited throughout their evolutionary history.
An efficient technique to retrieve information from a damaged near-field communication tag
Authors: Saeed Dawer , Iqbal Razi 
Published: March 2017

Purpose
The purpose of this paper is to discuss a technique of restoring data from a broken/damaged near-field communication (NFC) tag whose coil is damaged and seems unrecoverable.

Design/methodology/approach
This paper discusses a method to restore data from damaged NFC tags by designing a coil that matches the technical specification of NFC for restoring information. In this paper, an NFC tag with a broken antenna coil and its operational NFC chip is used for restoring data by making an external loop antenna for the same chip.

Findings
If the NFC tag is damaged, the information stored on the tag can be lost and can cause serious inconvenience. This research provides an excellent mechanism for retrieving all the information accurately from a damaged NFC tag provided the NFC chip is not damaged.

Research limitations/implications
One of the major limitations of this research is that the NFC chip remains intact without any damages. Data can only be recoverable if just the antenna of the NFC tag is damaged; any damage to the NFC chip would make it impossible for the data to be recoverable.

Practical implications
The research is carried out with limited resources in an academic institute and hence cannot be compared to antenna designs of the industry. Furthermore, industry vendors are using aluminum to design the coil; however, in this study a copper coil is used for coil design since it is far less expensive than aluminum coil.

Originality/value
NFC is a rather new short-range wireless technology and not much work is done in this field as far as antenna study is concerned. This study brings a technique to design a coil antenna for a damaged NFC tag to retrieve all the information without losing even a single bit of sensitive information.
A novel approach based on utility mining for store layout: a case study in a supermarket
Authors: Altuntas Serkan 
Published: March 2017

Purpose
The purpose of this paper is to propose a novel approach based on utility mining for store layout.

Design/methodology/approach
A utility mining-based data mining algorithm is utilized in this paper.

Findings
A real-life case study in a supermarket is conducted to illustrate the proposed approach. The findings show that the proposed approach can be used easily and efficiently to arrange store layout.

Research limitations/implications
There are two limitations to this study. First, space allocation to each product family is not considered. Second, product placement in each product family is not taken into account in the proposed approach.

Originality/value
In this paper, a novel approach is proposed for business intelligence in retail business. The proposed approach uses a utility-based data mining approach, namely, the high-utility itemset mining (HUIM) algorithm, to rearrange store layout and to determine the relations among product families. The quantities and prices of items purchased corresponding to product families are taken into account in the proposed approach to address the needs in practice. Business intelligence software is also developed as an integral part of the proposed approach to utilize the HUIM algorithm.
