Published: March 2016

AbstractThe Gilbert damping of ferromagnetic materials is arguably the most important but least understood phenomenological parameter that dictates real-time magnetization dynamics. Understanding the physical origin of the Gilbert damping is highly relevant to developing future fast switching spintronics devices such as magnetic sensors and magnetic random access memory. Here, we report an experimental study of temperature-dependent Gilbert damping in permalloy (Py) thin films of varying thicknesses by ferromagnetic resonance. From the thickness dependence, two independent contributions to the Gilbert damping are identified, namely bulk damping and surface damping. Of particular interest, bulk damping decreases monotonically as the temperature decreases, while surface damping shows an enhancement peak at the temperature of ~50 K. These results provide an important insight to the physical origin of the Gilbert damping in ultrathin magnetic films.

AbstractThe two-step nucleation model for crystal nuclei formation explains several experimental and theoretical results better than the classical nucleation theory. We report here direct visualization of the two-step nucleation model for organic molecular crystallization. Evaporative crystallization from a solution of a dibenzoylmethane boron complex that displays mechanofluorochromism, a fluorescence color change induced by mechanical perturbation, was probed by fluorescence change. The dependence of fluorescence change on dispersion concentration of the complex in a polymer matrix was also investigated. We detected transitional emission from the amorphous cluster state prior to crystallization. This is the first demonstration of the two-step nucleation model based on fluorescence color changes.

AbstractThe discovery of photoswitchable azobenzene-systems that undergo trans-to-cis photoisomerisation was a milestone in supramolecular chemistry. Such photoswitches have possible applications in data storage, stimuli responsive delivery systems and molecular machines due to fast and selective switching. However, the light induced cis isomer of azobenzene is rather unstable and reverts thermally and photochemically to the thermodynamically stable trans configuration. We report, for the first time, controlled photoswitching of an azo-naphthalenediimide (azo-NDI) which can be achieved upon binding of fluoride ions through anion-π interaction. This NDI-F–NDI “sandwich” stabilises the cis configuration through the generation of an NDI•− radical anion and a dianionic, NDI2− species that becomes unusually stable in the cis form. The sandwiched cis form reverts to the trans form only upon decomplexation of F−. A model pollutant was successfully degraded using the photogenerated NDI-F–NDI sandwich. This opens a wide range of applications in molecular and supramolecular nanotechnology.

AbstractLate-onset hypogonadism (i.e. androgen deficiency) raises the risk for abdominal obesity in men. The mechanism for this obesity is unclear. Here, we demonstrated that hypogonadism after castration caused abdominal obesity in high-fat diet (HFD)-fed, but not in standard diet (SD)-fed, C57BL/6J mice. Furthermore, the phenotype was not induced in mice treated with antibiotics that disrupt the intestinal microflora. In HFD-fed mice, castration increased feed efficiency and decreased fecal weight per food intake. Castration also induced in an increase of visceral fat mass only in the absence of antibiotics in HFD-fed mice, whereas subcutaneous fat mass was increased by castration irrespective of antibiotics. Castration reduced the expression in the mesenteric fat of both adipose triglyceride lipase and hormone-sensitive lipase in HFD-fed mice, which was not observed in the presence of antibiotics. Castration decreased thigh muscle (i.e. quadriceps and hamstrings) mass, elevated fasting blood glucose levels and increased liver triglyceride levels in a HFD-dependent manner, whereas these changes were not observed in castrated mice treated with antibiotics. The Firmicutes/Bacteroidetes ratio and Lactobacillus species increased in the feces of HFD-fed castrated mice. These results show that androgen (e.g. testosterone) deficiency can alter the intestinal microbiome and induce abdominal obesity in a diet-dependent manner.
Effect of depth and soil moisture on buried ultra‐wideband antenna

Published: March 2016

Ultra‐wideband (UWB) wireless underground sensor networks consist of wirelessly connected underground sensor nodes that communicate through the soil. Performances of buried antennas and of the communication link depend on the soil dielectric characteristics. The effects of soil moisture and depth, in the frequency band of 3.1–10.6 GHz, on an UWB antenna return loss and bandwidth are presented. The measurements are conducted in two different types of soil: sandy soil and railway pebbles. The experimental results show that burying antenna shifts down its bandwidth. This phenomenon is accentuated by the increase of soil moisture and not impacted by the burial depth variations. In a dry sandy soil, the shift of the bandwidth low‐end is of 0.75 GHz, while it is 1 and 1.5 GHz at 5 and 20% soil moisture, respectively. This fact has allowed us to further miniaturise the used antenna.

Published: March 2016

A novel and low‐cost method for fabricating poly(methyl methacrylate) micronanotube arrays (PMMA‐MNAs) using a porous anodic aluminium (PAA) template and spin‐coating method was presented. PMMA‐MNAs with different length micronanotubes were fabricated by changing the temperature of electric heating drying oven and heating time, then characterised by field‐emission scanning electron microscope. Experimental results showed that the poly(methyl methacrylate) (PMMA) liquid membrane was obtained by means of spin coating at the spin velocity of 4000 r/min, and can further grow into PMMA‐MNAs using an all‐through‐pore PAA film as template at a certain temperature. The length of PMMA‐MNAs increased nonlinearly with the increasing of the oven temperature and trended to a stable value (about 6.51 μm) at 150°C for 1.5 h. Flexible PMMA‐MNAs with characteristics of hollow structure will have wide application prospects in catalyst carrier, high precise sensor, drug sustained release and so on. The presented experimental results could facilitate understanding the growth mechanism of polymer nanotube arrays.

Study Design Systematic review and meta-analysis. Objective To compare the recurrence and perioperative complication rate of en bloc vertebrectomy (EV) and intralesional resection (IR) in the giant cell tumor of the mobile spine (SGCT). Methods We systematically searched publications in the PubMed and Embase databases for reports of SGCTs, excluding the sacrum. Two reviewers independently assessed all publications. A meta-analysis was performed using local recurrence and postoperative complications as the primary outcomes of interest. Results There were four articles reporting recurrence and two articles reporting postoperative complications. All included articles were case series. In all, 91 patients were included; 49 were treated with IR and 42 were treated with EV. Local recurrence rates were 36.7 and 9.5% in the IR and EV groups, respectively. Rates of postoperative complications were 36.4% with IR and 11.1% with EV. Overall, patients treated with EV not only had a lower recurrence rate (relative risk [RR] 0.22; 95% confidence interval [CI] 0.09 to 0.52) but also had a lower postoperative complication rate (RR 0.34; 95% CI 0.07 to 1.52) compared with IR. Conclusions Based on the limited data obtained from systematic review, SGCT patients treated with EV had a lower recurrence rate and fewer postoperative complications than those treated with IR.

Significance
With the spectacular advance of DNA-sequencing technology, a rapidly increasing number of subtle gene variants in the human population are being identified. One approach to understanding their impact on health and disease is to re-create these variants in appropriate cell lines that are accessible to functional analyses. We present a design principle for synthetic short single-stranded DNA oligonucleotides (ssODNs) that enables effective gene modification in DNA mismatch repair (MMR)-proficient cells. We report that the placement of locked nucleic acids at mismatching bases evades MMR. Its precision, simplicity, and cost-effectiveness makes ssODN-directed gene modification an attractive way of generating large numbers of sequence variants, in particular when they can be evaluated by scoring an easily detectable phenotype.
Spawning Site Fidelity, Catchment, and Dispersal of Common Snook along the East Coast of Florida

Published: March 2016

AbstractA population's fidelity to spawning sites and variation in the strength of site fidelity among individuals are influential components of fish population dynamics. The literature on fidelity to aggregation sites is dominated by studies on marine species, whereas less is known about the fidelity of euryhaline species to spawning aggregation sites. We used passive acoustic telemetry to quantify intra‐annual and interannual site fidelity and resident habitat associated with spawning sites (inlets) for 280 sexually mature Common Snook Centropomus undecimalis through an array of more than 200 receivers deployed in rivers, estuaries, inlets, and nearshore waters along 320 km of Florida's Atlantic coast. Fish were detected four times as often at and made twice as many trips to a primary spawning inlet than to secondary inlet sites. Fish displayed interannual site fidelity, returning to the primary inlet for as many as five consecutive reproductive seasons. Overall, individuals returned to their primary inlet (return rate [RR] = 0.54) more often than they changed sites between years (straying rate [SR] = 0.29), but variation in RRs and SRs between inlets suggested a spatial effect on interannual site fidelity. During the nonspawning season, fish generally resided less than 40 km to the northwest of their primary inlet. The 95% kernel density estimates (KDEs) for catchment area and dispersal area averaged 220 km2 and overlapped greatly for five out of six inlets. The 50% KDE did not overlap between inlets, suggesting that each spawning site had a corresponding winter resident habitat supporting a group of fish that were primarily associated with that inlet. The inclusion of telemetry data in traditional measures of site fidelity allowed for the identification and accurate description of behavioral polymorphism and may be applied to other fish species when spatial substructuring is suspected.Received June 9, 2015; accepted December 3, 2015
Biphasic and triphasic dose responses in zebrafish embryos to low-dose 150 kV X-rays with different levels of hardness
Authors: Kong Eva Yi , Cheng Shuk Han , Yu Kwan Ngok 
Published: March 2016

Abstract
The in vivo low-dose responses of zebrafish ( Danio rerio ) embryos to 150 kV X-rays with different levels of hardness were examined through the number of apoptotic events revealed at 24 h post fertilization by vital dye acridine orange staining. Our results suggested that a triphasic dose response was likely a common phenomenon in living organisms irradiated by X-rays, which comprised an ultra-low-dose inhibition, low-dose stimulation and high-dose inhibition. Our results also suggested that the hormetic zone (or the stimulation zone) was shifted towards lower doses with application of filters. The non-detection of a triphasic dose response in previous experiments could likely be attributed to the use of hard X-rays, which shifted the hormetic zone into an unmonitored ultra-low-dose region. In such cases where the subhormetic zone was missed, a biphasic dose response would be reported instead.

Abstract
We present deep new Gran Telescopio Canarias (GTC) narrow-band images and William Herschel Telescope (WHT) long-slit spectroscopy of the merging system Mrk273 that show a spectacular extended halo of warm ionized gas out to a radius of ∼45 kpc from the system nucleus. Outside of the immediate nuclear regions (r &gt; 6 kpc), there is no evidence for kinematic disturbance in the ionized gas: in the extended regions covered by our spectroscopic slits the emission lines are relatively narrow (full width at half-maximum, FWHM ≲ 350 km s−1) and velocity shifts small (|ΔV| ≲ 250 km s−1). This is despite the presence of powerful near-nuclear outflows (FWHM &gt; 1000 km s−1; |ΔV| &gt; 400 km s−1; r &lt; 6 kpc). Diagnostic ratio plots are fully consistent with Seyfert 2 photoionization to the NE of the nuclear region, however to the SW the plots are more consistent with low-velocity radiative shock models. The kinematics of the ionized gas, combined with the fact that the main structures are aligned with low-surface-brightness tidal continuum features, are consistent with the idea that the ionized halo represents tidal debris left over from a possible triple-merger event, rather than a reservoir of outflowing gas.
Detection of Bacteriuria by Canine Olfaction

Published: March 2016

Abstract
Background.  Urinary tract infections (UTIs) are a significant medical problem , particularly for patients with neurological conditions and the elderly. Detection is often difficult in these patients, resulting in delayed diagnoses and more serious infections such as pyelonephritis and life-threatening sepsis. Many patients have a higher risk of UTIs because of impaired bladder function, catheterization, and lack of symptoms. Urinary tract infections are the most common nosocomial infection; however, better strategies are needed to improve early detection of the disease.
Methods.  In this double-blinded, case-control, validation study, we obtained fresh urine samples daily in a consecutive case series over a period of 16 weeks. Dogs were trained to distinguish urine samples that were culture-positive for bacteriuria from those of culture-negative controls, using reward-based clicker and treat methods.
Results.  Samples were obtained from 687 individuals (from 3 months to 92 years of age; 86% female and 14% male; 34% culture-positive and 66% culture-negative controls). Dogs detected urine samples positive for 100 000 colony-forming units/mL Escherichia coli (N = 250 trials; sensitivity 99.6%, specificity 91.5%). Dilution of E coli urine with distilled water did not affect accuracy at 1% (sensitivity 100%, specificity 91.1%) or 0.1% (sensitivity 100%, specificity 93.6%) concentration. Diagnostic accuracy was similar to Enterococcus (n = 50; sensitivity 100%, specificity 93.9%), Klebsiella (n = 50; sensitivity 100%, specificity 95.1%), and Staphylococcus aureus (n = 50; sensitivity 100%, specificity 96.3%). All dogs performed with similarly high accuracy: overall sensitivity was at or near 100%, and specificity was above 90%.
Conclusions.  Canine scent detection is an accurate and feasible method for detection of bacteriuria.

Abstract

Objective:
Diabetes mellitus (DM) and systemic hypertension (SH) are frequent benign diseases which might coexist with endometrial polyps. We sought to evaluate whether women who suffer from these diseases have an increased incidence of premalignant and malignant lesions.

Methods:
We systematically searched the literature using the Medline (by using Pubmed) (1966-2015), Scopus (2004-2015), ClinicalTrials.gov (2008-2015), Cochrane Central Register (CENTRAL), and Google Scholar (2004-2015) databases along with the references of all articles which were retrieved in full text. We performed the meta-analysis with the RevMan 5.1 software.

Results:
Both DM and SH seem to be correlated with increased odds of developing premalignant and malignant endometrial polyps (odds ratio 2.43, 95% confidence interval 1.51, 3.91) and (odds ratio 2.36, 95% confidence interval 1.16, 4.81). However, it remains unclear whether type I or type II DM exert a more pronounced effect and whether the severity of SH has an impact on these odds. Also, the potential relation of antidiabetic and antihypertensive treatment with these lesions cannot be excluded.

Conclusions:
Physicians should increase their awareness among women with endometrial polyps who suffer from DM and/or SH. Further studies are needed to corroborate our findings and elucidate the underlying mechanisms of this relation.
Omura’s whale (Balaenoptera omurai) stranding on Qeshm Island, Iran: further evidence for a wide (sub)tropical distribution, including the Persian Gulf

AbstractA small, juvenile rorqual live-stranded on Qeshm Island, Iran, in the northern Strait of Hormuz (Persian Gulf) in September 2007. Cause of stranding remains unknown but the whale (QE22.09.2007) showed no severe traumatic injuries nor was emaciated. Based on at least seven morphological features, considered diagnostic in combination, allowed a positive identification as Omura’s whaleBalaenoptera omurai. Features included diminutive body size (397 cm), a large number of ventral grooves (n=82) extending caudad of the umbilicus, a strongly falcate dorsal fin, asymmetric colouration of the head (especially lower jaws) reminiscent of fin whale, including three unilateral dark stripes, faint/incomplete lateral rostral ridges, record low number of short, broad baleen plates (204 in right jaw). The likelihood for the existence of a localB. omuraipopulation in the eastern Persian Gulf or northern Arabian Sea seems higher than the wandering of a very young animal or mother/calf pair from any of the known distant distribution areas in the eastern Indian Ocean or SW Indian Ocean (Madagascar). This is the first record ofB. omuraiin the NW Indian Ocean.
The role of management accounting and control in making professional organizations horizontal
Authors: Kastberg Gustaf , Siverbo Sven 
Published: March 2016

Purpose– In the last decade, greater attention has been paid to the role of management accounting and control (MAC) in making professional organizations more horizontal. The authors argue that earlier research has not shown how the interrelatedness between professional identities and MAC influences attempts to make organizations more horizontal. In this paper the authors respond to the call for more research on the relationship between horizontalization and accounting and control. The purpose of this paper is to contribute to the emerging literature on the relationship between accountability arrangements and professional identities.Design/methodology/approach– Theoretically the authors have an actor-network theory (ANT) approach. Empirically, the authors followed two episodes where actors at top management levels in two Swedish health care organizations introduced horizontalization.Findings– The two episodes support the view that the role of MAC when making professional organizations more horizontal is limited. Professionals dominate what happens at the operational level and they do not act on MAC rules and performance targets in opposition of their professional identity. However, in alliance with other interessement devices MAC may have a role in creating overflows, that is, pointing out imperfections in the existing frame. The authors noticed no signs that professionals developed hybrid identities as in previous research.Originality/value– The authors apply ANT to move beyond the commonly used contingency and new institutional sociology perspectives.
The big leap: a story of the public accounting firm that wanted to become a cooperative
Authors: Jaumier Stéphane 
Published: March 2016

Purpose– While a comparative study of the literature on accounting as a profession and on cooperatives reveals important differences in the values embodied by certified public accountants and by cooperators, the purpose of this study is to explore whether such differences lead to an insurmountable incompatibility or may possibly be mitigated and eventually overcome.Design/methodology/approach– The study focuses on a French public accounting firm’s project to become a worker cooperative. Drawing on methodological insights from actor–network theory (ANT), the study analyses a situation in which the certified public accountants try to convince some cooperators of the merits of their project.Findings– The case studied suggests that accounting as a profession and cooperatives are irreconcilable. It not only confirms that some of their contrasting features (identified in the literature) are indeed too difficult to overcome but also reveals a new, unforeseen source of tension between certified public accountants and cooperators.Research limitations/implications– The study calls for further research into the so-far-overlooked relationships between accounting as a profession and cooperatives. It also proposes to extend the usage of ANT in accounting research to the study of accounting as a profession.Originality/value– While ANT-inspired accounting research has to date shown a dominant interest in successful translation processes, the present study looks at an unsuccessful translation stage.
