Published: December 2018

AbstractThe degradation of the Zn|polymer interface is inhibited by CO2 gas in a humid environment. The inhibition mechanism varies greatly for different polymer matrices and depends on the affinity of the polymer to CO2. Coatings based on polymers with high affinity to CO2 such as polyacrylamide show high delamination rates due to the fast uptake of water. In this case, the cation transport that causes the initial pull down of potential for initiating the oxygen reduction reaction occurs via the polymer. Here CO2 decreases water uptake due to competitive absorption into the polymer matrix, inhibiting the delamination rate. CO2 can quickly reach the interface of polymers with functional groups with a low affinity to water and CO2, such as polyvinyl butyral and polyvinyl alcohol. In this case, the inhibition of the delamination rate is achieved by a strong decrease in cation migration rate at the Zn|polymer interface accompanied by the formation of mixed hydrozincite/absorbed CO2 layers on the ZnO surface underneath the polymers. Further experiments showed that the presence of CO2 accelerates anion migration, suggesting an influence of CO2 on the surface charge at the Zn|coating interface, thus affecting ion migration. Inhibition of cation migration has never been reported before and should be taken into account into the mechanism of cathodic-driven delamination on Zn under atmospheric conditions.

AbstractThe divergent nematic susceptibility, obeying a simple Curie-Weiss power law over a large temperature interval, is empirically found to be a ubiquitous signature in several iron-based materials across their doping-temperature phase diagram. The composition at which the associated Weiss temperature extrapolates to zero is found to be close to optimal doping, boosting the debate to what extent nematic fluctuations contribute to the pairing-mechanism and generally affect the electronic structure of iron-based superconductors. Here, we offer a comprehensive optical investigation of the optimally hole-doped Ba0.6K0.4Fe2As2 over a broad spectral range, as a function of temperature and of tunable applied stress, which acts as an external symmetry breaking field. We show that the stress-induced optical anisotropy in the infrared spectral range is reversible upon sweeping the applied stress and occurs only below the superconducting transition temperature. These findings demonstrate that there is a large electronic nematicity at optimal doping which extends right under the superconducting dome.

AbstractThe effective manipulation of excitons is important for the realization of exciton-based devices and circuits, and doping is considered a good strategy to achieve this. While studies have shown that 2D semiconductors are ideal for excitonic devices, preparation of homogenous substitutional foreign-atom-doped 2D crystals is still difficult. Here we report the preparation of homogenous monolayer Sb-doped MoS2 single crystals via a facile chemical vapor deposition method. A and B excitons are observed in the Sb-doped MoS2 monolayer by reflection magnetic circular dichroism spectrum measurements. More important, compared with monolayer MoS2, the peak positions of two excitons show obvious shifts. Meanwhile, the degeneration of A exciton is also observed in the monolayer Sb-doped MoS2 crystal using photoluminescence spectroscopy, which is ascribed to the impurity energy levels within the band-gap, confirmed by density function theory. Our study opens a door to developing the doping of 2D layered transition metal dichalcogenides with group-V dopants, which is helpful for the fundamental study of the physical and chemical properties of transition metal dichalcogenides.

AbstractLow back pain (LBP) is the leading cause of disability throughout the world and is economically burdensome. The recommended first line treatment for non-specific LBP is non-invasive care. A digital care program (DCP) delivering evidence-based non-invasive treatment for LBP can aid self-management by engaging patients and scales personalized therapy for patient-specific needs. We assessed the efficacy of a 12-week DCP for LBP in a two-armed, pre-registered, randomized, controlled trial (RCT). Participants were included based on self-reported duration of LBP, but those with surgery or injury to the lower back in the previous three months were excluded. The treatment group (DCP) received the 12-week DCP, consisting of sensor-guided exercise therapy, education, cognitive behavioral therapy, team and individual behavioral coaching, activity tracking, and symptom tracking – all administered remotely via an app. The control group received three digital education articles only. All participants maintained access to treatment-as-usual. At 12 weeks, an intention-to-treat analysis showed each primary outcome—Oswestry Disability Index (p < 0.001), Korff Pain (p < 0.001) and Korff Disability (p < 0.001)—as well as each secondary outcome improved more for participants in the DCP group compared to control group. For participants who completed the DCP (per protocol), average improvement in pain outcomes ranged 52-64% (Korff: 48.8–23.4, VAS: 43.6–16.5, VAS impact on daily life: 37.3–13.4; p < 0.01 for all) and average improvement in disability outcomes ranged 31–55% (Korff: 33.1–15, ODI: 19.7–13.5; p < 0.01 for both). Surgical interest significantly reduced in the DCP group. Participants that completed the DCP had an average engagement, each week, of 90%. Future studies will further explore the effectiveness of the DCP for long-term outcomes beyond 12 weeks and for a LBP patient population with possibly greater baseline pain and disability. In conclusion, the DCP resulted in improved LBP outcomes compared to treatment-as-usual and has potential to scale personalized evidence-based non-invasive treatment for LBP patients.

AbstractDrought-induced tree death has become a serious problem in global forest ecosystems. Two nonexclusive hypotheses, hydraulic failure and carbon starvation, have been proposed to explain tree die-offs. To clarify the mechanisms, we investigated the physiological processes of drought-induced tree death in saplings with contrasting Huber values (sapwood area/total leaf area). First, hydraulic failure and reduced respiration were found in the initial process of tree decline, and in the last stage carbon starvation led to tree death. The carbohydrate reserves at the stem bases, low in healthy trees, accumulated at the beginning of the declining process due to phloem transport failure, and then decreased just before dying. The concentrations of non-structural carbohydrates at the stem bases are a good indicator of tree damage. The physiological processes and carbon sink-source dynamics that occur during lethal drought provide important insights into the adaptive measures underlying forest die-offs under global warming conditions.
Observational signatures of magnetic field structure in relativistic AGN jets
Authors: Prior Christopher , Gourgouliatos Konstantinos N. 
Published: December 2018

Context. Active galactic nuclei (AGN) launch highly energetic jets sometimes outshining their host galaxy. These jets are collimated outflows that have been accelerated near a supermassive black hole located at the centre of the galaxy. Their, virtually indispensable, energy reservoir is either due to gravitational energy released from accretion or due to the extraction of kinetic energy from the rotating supermassive black hole itself. In order to channel part of this energy to the jet, though, the presence of magnetic fields is necessary. The extent to which these magnetic fields survive in the jet further from the launching region is under debate. Nevertheless, observations of polarised emission and Faraday rotation measure confirm the existence of large scale magnetic fields in jets.Aims. Various models describing the origin of the magnetic fields in AGN jets lead to different predictions about the large scale structure of the magnetic field. In this paper we study the observational signatures of different magnetic field configurations that may exist in AGN jets in order to asses what kind of information regarding the field structure can be obtained from radio emission, and what would be missed.Methods. We explore three families of magnetic field configurations. First, a force-free helical magnetic field corresponding to a dynamically relaxed field in the rest frame of the jet. Second, a magnetic field with a co-axial cable structure arising from the Biermann-battery effect at the accretion disk. Third, a braided magnetic field that could be generated by turbulent motion at the accretion disk. We evaluate the intensity of synchrotron emission, the intrinsic polarization profile and the Faraday rotation measure arising from these fields. We assume that the jet consists of a relativistic spine where the radiation originates from and a sheath containing thermalised electrons responsible for the Faraday screening. We evaluate these values for a range of viewing angles and Lorentz factors. We account for Gaussian beaming that smooths the observed profile.Results. Radio emission distributions from the jets with dominant large-scale helical fields show asymmetry across their width. The Faraday rotation asymmetry is the same for fields with opposing chirality (handedness). For jets which are tilted towards the observer the synchrotron emission and fractional polarization can distinguish the field’s chirality. When viewed either side-on or at a Blazar type angle only the fractional polarization can make this distinction. Further this distinction can only be made if the direction of the jet propagation velocity is known, along with the location of the jet’s origin. The complex structure of the braided field is found not to be observable due to a combination of line of sight integration and limited resolution of observation. This raises the possibility that, even if asymmetric radio emission signatures are present, the true structure of the field may still be obscure.

ZUSAMMENFASSUNGEine automatische Dosierung von Insulin, Blutzuckerwerte im Zielbereich und ungestörter Schlaf – ein Traum vieler Menschen mit Diabetes und ihrer Familien, der sich durch die selbst gebaute „künstliche Bauchspeicheldrüse“ bereits für einige erfüllt hat. #WeAreNotWaiting – dahinter steht eine innovative Bewegung engagierter Patienten und Patientinnen und ihrer Angehörigen, die sich ihre Diabetestechnologie selbst erstellen, bis hin zum „Closed Loop“, welcher Insulin je nach Glukosespiegel automatisch dosiert. Da jedes Do-it-Yourself-System ein Selbstexperiment auf eigenes Risiko unter Nutzung eines nicht zugelassenen Produkts ist, ergeben sich zahlreiche Fragestellungen hinsichtlich Sicherheit und Risiken, und auch bezüglich der Haftung bei der Nutzung dieser Systeme. Weiterhin stellt sich aber vor allem auch die zentrale Frage: Warum müssen wir eigentlich so lange auf Closed-Loop-Systeme warten?
The Evidence for Adjunctive Facelift Procedures
Authors: Edmondson Sarah-Jayne , Grover Rajiv , Urso-Baiarda Fulvio 
Published: December 2018

AbstractFacelift surgery is a popular treatment but exhibits high variation among practitioners in terms of both core technique and adjunctive measures. This review identified significant evidence addressing the role of pre-infiltration, drains, fat grafting, fibrin tissue adhesives, hilotherapy, and other miscellaneous adjuncts. Based on the authors' assessment of the current literature, there is reasonable supportive evidence for pre-infiltration, fat grafting and laser skin resurfacing, which appear to be safe and effective in appropriately selected patients. Drain use is not mandatory but may confer some benefit. Conversely the evidence for the use of fibrin tissue adhesives and hilotherapy is not compelling.
Free Flap Head and Neck Reconstruction with an Emphasis on Postoperative Care
Authors: D'Souza Jacob , King Wendy , Bater Michael , van Gijn Daniel 
Published: December 2018

AbstractMicrosurgical free tissue transfer represents the mainstay of care in both ablative locoregional management and the simultaneous reconstruction of a defect. Advances in microsurgical techniques have helped balance the restoration of both form and function—decreasing the significant morbidity once associated with large ablative, traumatic, or congenital defects—while providing immediate reconstruction enabling early aesthetic and functional rehabilitation. There are a multitude of perioperative measures and considerations that aim to maximize the success of free tissue transfer. These include nutritional support, tight glycemic control, acknowledgment of psychological and psychiatric factors, intraoperative surgical technique, and close postoperative monitoring of the patients' hemodynamic physiology. While the success rates of free tissue transfer in experienced hands are comparable to alternative options, the consequences of flap failure are catastrophic—with the potential for significant patient morbidity, prolonged hospital stay (and associated increased financial implications), and increasingly limited options for further reconstruction. Success is entirely dependent on a continuous arterial inflow and venous outflow until neovascularization occurs. Flap failure is multifactorial and represents a dynamic process from the potentially reversible failing flap to the necrotic irreversibly failed flap—necessitating debridement, prolonged wound care, and ultimately decisions concerned with future reconstruction. The overriding goal of free flap monitoring is therefore the detection of microvascular complications prior to permanent injury occurring—identifying and intervening within that critical period between the failing flap and the failed flap—maximizing the potential for salvage. With continued technique refinement, microvascular free flap reconstruction offers patients the chance for both reliable functional and aesthetic restoration in the face of significant ablative defects. The caveat to this optimism is the requirement for considered perioperative care and the optimization of those factors that may offer the difference between success and failure.

Published: December 2018

AbstractIn any kind of surgery, postoperative care is essential for a good result, but especially when the matter at stake is facial plastic surgery. Despite having performed a perfect surgery, with the least amount of damage to the soft tissues and osteocartilaginous structures, minimal bleeding, and in terms of the surgical time, without adequate postoperative care our results can be affected considerably in the short and long run. Therefore, we must have very clear guidelines regarding postoperative care and the duties of our patients, which should be emphasized during the informed consent of the intervention. It is also essential to comment on the warning signs of postoperative complications, which need to be detected and treated in time to achieve the expected post-surgery results. Before being discharged from the hospital, the patient again receives the postoperative instructions, as well as receiving a paper copy to avoid any possible misunderstandings. In this article, we will detail the postoperative care and complications of brow lift and upper and lower blepharoplasty.

Published: December 2018

AbstractAfter rhinoplasty, during the first 24 hours, the patients should be closely monitored for pain and discomfort, nausea and vomiting, and cool compresses must be applied regularly to decrease edema and ecchymosis. In the early postoperative period of the first month, the sutures, cast, and splints are usually removed during the first week. Then the patient is followed-up at 1, 3, 6, and 12-month intervals routinely to observe healing. In the meantime, any kind of intranasal and extranasal complications should be noted. The outcome measures such as ROE, NOSE, or SCHNOS should be used 3 to 6 months after surgery. If the patient is closely followed-up, then any unwanted complication or dissatisfaction can be solved after 6 to 12 months.
Postoperative Care in Facial Implants
Authors: Eppley Barry , Perkins Stephen , Floyd Elizabeth 
Published: December 2018

AbstractFacial augmentation is a growing field, secondary to the appreciation of the changes seen in the facial skeleton with aging and the growing acceptance/popularity of facial fat grafting and facial fillers. In addition, it plays a significant role in patients with congenital facial deficiencies as well as those interested in facial feminization/masculinization surgery. Several facial implants are discussed in this article including classic facial implants such as malar, submalar, chin, and prejowl implants as well as newer facial implants such as mandible, temporal, forehead, and skull implants. Special care is given to the postoperative care of these implants. Custom-made implants with three-dimensional computed tomography reconstruction are also discussed
The Military ACL
Authors: Posner Matthew , Tennent David 
Published: December 2018

AbstractAnterior cruciate ligament (ACL) injuries in the U.S. Military Service members have a 10-fold higher incidence than that of the general population due to the physically demanding aspects of military duties. Although some controversy exists on the specific techniques or reconstruction, these injuries are uniformly reconstructed due to the requirements of their occupation and the effect of these injuries on their future careers. As such, understanding the care of the military Service member's ACL may help optimize the care of the physically active injured knee.
Hexing the discipline: against the reproduction of continental philosophy of religion
Authors: Rose Marika , Smith Anthony Paul 
Published: December 2018

AbstractThere has been a generalised anxiety concerning the future of continental philosophy of religion as a discipline, with a number of books, articles, conferences, and presentations taking up this theme. This anxiety exists because as a discipline continental philosophy of religion lacks a clear claim to an identity. This article analyses the anxiety concerning the future of continental philosophy of religion as an anxiety of reproduction. By locating the philosopher’s anxiety within a wider anxiety of reproduction we begin to understand this anxiety through the queer anti-social critique of Lee Edelman. This anxiety is traced through three processes of reproduction: intellectual reproduction, disciplinary reproduction, and institutional reproduction. The article goes on to sketch out a position against the reproduction of continental philosophy of religion by taking on and celebrating the discipline’s improper nature. Appealing neither to secular reason nor to established traditions, we draw on the Malleus Maleficarum (as read through queer theory and non-philosophy) to craft various models for thought. Here we find abortion prized over the future of the race, miscegenation over blood purity, and impotence and infertility over the sovereign power of the father. These models are explored both in terms of their historical context and as providing a different image of the work that can be carried out in the discipline of continental philosophy of religion. The article concludes by suggesting other perverse lines of relation that may be opened up when one gives up on the reproduction of the discipline.

Significance
Scaffold proteins are key regulators of signal transduction that bind multiple proteins of a signaling pathway. This simple tethering model explains how the scaffold colocalizes the components for signal propagation, but it is unclear whether scaffolds ensure signal amplification. Here, we use arrestin-3 and the ASK1-MKK4/7-JNK3 kinase cascade as a model system to explore whether scaffolding amplifies signaling. Our studies suggest a model of scaffold-dependent signal amplification that may be conceptually applicable to other scaffold-dependent signaling pathways.

Abstract
Fuel cell has two essential problems, its cost and the durability, which hinder its commercialization. Platinum is the ideal catalyst that has high activity, stability and selectivity but has high cost. An attempt has been done to find a cheaper catalyst instead of platinum. Zinc oxide nanoparticles were synthesized via sol-gel method using zinc acetate and citric acid in basic media with different calcination temperatures (420, 520 and 620 °C). From X-ray diffraction (XRD) patterns, the calculated particles size is 7.7, 15.6 and 19.3 nm as the calcination temperature of 420, 520 and 620°C, respectively, indicating that the particles size increases with increasing the calcination temperature. Different concentrations (5 and 10 wt.%) of ZnO nanoparticles with 10 wt.% polyvinyl alcohol (PVA) were prepared and calcinated at 750 °C to get carbon/ZnO as a catalyst for fuel cell applications. A carbon core-shell surrounding by mono-disperse ZnO nanoparticles with large surface area that required for the new catalyst with believable morphology was shown by transmission electron microscope (TEM). Also, XRD presents high purity of the new composite with uniformly distinguishable peaks. Fourier transformation infrared (FTIR) spectroscopy shows the change in the carbon/ZnO nanoparticles spectra due to ZnO characteristic vibration band at 440-460 cm−1. Cyclic voltammetry (CV) exhibits a good promising catalytic activity and current density with oxidation behaviour is reported. Finally, ZnO used to enhance carbon electrochemically performance as a result of a novel non-precious catalyst.
