Relaciones entre civiles y militares durante el Oncenio de Augusto Leguía (Perú, 1919-1930)
Authors: Camacho Arango Carlos
Published: May 2016

Through an analysis of unpublished foreign military sources, this article examines the conflictive relations between Peruvian civilians and members of the military during a civil government: the Oncenio of Augusto Leguía (1919-1930). The classic question about South American military forces —Why they carry out coups d’etat so often?— is substituted by another, much broader one: How did they function politically? In the early 1920s, the Peruvian army was fragmented: some officers supported the central government and others opposed it. Those that supported the regime were rewarded, while those who took action against it did so outside of Lima, frequently hand-in-hand with civilian leaders, guided by officers of the rank of lieutenant coronel and below, and probably in reaction to measures taken by president Leguía against the army as an institution or against specific officers.

Introduction

Antiretroviral therapy (ART) prevents HIV transmission within HIV serodiscordant couples (SDCs), but slow implementation and low uptake has limited its impact on population‐level HIV incidence. Home HIV testing and counselling (HTC) campaigns could increase ART uptake among SDCs by incorporating couples’ testing and ART referral. We estimated the reduction in adult HIV incidence achieved by incorporating universal ART for SDCs into home HTC campaigns in KwaZulu‐Natal (KZN), South Africa, and southwestern (SW) Uganda.

Methods

We constructed dynamic, stochastic, agent‐based network models for each region. We compared adult HIV incidence after 10 years under three scenarios: (1) “Current Practice,” (2) “Home HTC” with linkage to ART for eligible persons (CD4 <350) and (3) “ART for SDCs” regardless of CD4, delivered alongside home HTC.

Results

ART for SDCs reduced HIV incidence by 38% versus Home HTC: from 1.12 (95% CI: 0.98–1.26) to 0.68 (0.54–0.82) cases per 100 person‐years (py) in KZN, and from 0.56 (0.50–0.62) to 0.35 (0.30–0.39) cases per 100 py in SW Uganda. A quarter of incident HIV infections were averted over 10 years, and the proportion of virally suppressed HIV‐positive persons increased approximately 15%.

Conclusions

Using home HTC to identify SDCs and deliver universal ART could avert substantially more new HIV infections than home HTC alone, with a smaller number needed to treat to prevent new HIV infections. Scale‐up of home HTC will not diminish the effectiveness of targeting SDCs for treatment. Increasing rates of couples’ testing, disclosure, and linkage to care is an efficient way to increase the impact of home HTC interventions on HIV incidence.

In this study, a structure of Pt/Cu18Si12O70/TiN has been investigated. By co-sputtering the Cu and SiO2 targets in the switching layer, we can measure the operation mechanism of complementary resistive switching (CRS). This differs from conventional conductive bridge random access memory (CBRAM) that tends to use Cu electrodes rather than Cu18Si12O70. By changing the voltage and compliance current, we can control device operating characteristics. Because Cu distributes differently in the device depending on this setting, the operating end can be located at either the top or bottom electrode. Device current–voltage (I–V) curves are used to demonstrate that the CRS in the CBRAM device is a double-electrode operation.
Self-formation of microporous polysulfone hollow fiber using a single nozzle spinneret and reduction of phase-inversion speed
Authors: Kim Hyung Jin , Jang Chang Sik , Kim Byeong Hee , Seo Young Ho
Published: May 2016

This study proposed a simple fabrication technique for microporous hollow fibers whose inner channel was naturally formed because of a slow phase inversion speed. Conventionally, microporous hollow fibers have been fabricated by extruding a polymer solution through the outer nozzle and a bore liquid through the inner nozzle of a dual nozzle spinneret. Injecting a bore liquid played a key role for the formation of a hollow structure. In this study, the self-formation of a hollow structure of microporous fiber was developed using a single nozzle spinneret without a bore liquid. A sharp tip single nozzle spinneret of 200 µm in diameter was fabricated by the wetting effect of a liquid pre-polymer of polydimethylsiloxane, and polysulfone solution was extruded through the prepared single nozzle spinneret. The temperature of the coagulant bath was controlled in order to reduce the speed of phase change, because the phase-change speed depended on the temperature of the coagulant solution. An inner channel in the microporous fiber was successfully fabricated by reducing the phase-change speed and by increasing the solidification speed. The inner diameter of the microporous hollow fiber was decreased as the temperature of the coagulant bath was increased, and eventually the inner channel was not formed at the higher bath temperature rather than 25 °C.
Influence of gallium ion beam acceleration voltage on the bend angle of amorphous silicon cantilevers

Published: May 2016

This paper describes a plastic reshaping technique for Si thin membranes by using focused ion beam (FIB) processing. FIB is used to locally pattern and implant Ga ions into the membranes. The combination of Ga ion doping and alkali wet etching enables us to fabricate nanometer-thick Ga-ion-doped amorphous Si membranes, which can be bent upward at arbitrary angle by controlling the FIB beam irradiation condition. The bending mechanism is discussed in the light of Ga ions implanted depth from the membrane surface. By using this technique, a micrometer-sized chute structure with several different angles is produced.
Thermoreflectance-based in-depth stress distribution measurement technique for single-crystal silicon structures
Authors: Miyake Shugo , Kato Takaaki , Taguchi Hideyuki , Namazu Takahiro
Published: May 2016

In this paper, we suggest a new stress measurement technique based on the thermoreflectance method for the estimation of the in-depth stress distribution of fabricated silicon devices. Changing the modulated intensity of a heating laser beam of the frequency-domain thermoreflectance method (FD-TRM) can vary the estimation depth optionally. We developed a measurement system on the basis of the FD-TRM and demonstrated in-depth stress measurement for a single-crystal silicon (SCS) sample. The result measured at a modulation frequency of 3 MHz showed the phase distribution of the TR signal corresponding to the stress distribution determined by 632-nm-excited Raman spectroscopy. In addition, it was found that the phase distribution changed depending on the modulation frequency. The FD-TRM can be a powerful technique for estimating the in-depth stress distribution of silicon materials.
Utilizing immunomarking techniques to trackHalyomorpha halys(Hemiptera: Pentatomidae) movement and distribution within a peach orchard
Authors: Blaauw Brett R. , Jones Vincent P. , Nielsen Anne L.
Published: May 2016

In this study we focus on the invasive brown marmorated stink bug,Halyomorpha halys(Stål) (Hemiptera: Pentatomidae), which has a strong dispersal capacity and has had a significant impact on several cropping systems, including peach (Prunus persica(L.)). Management ofH. halyshas relied on intensive insecticide use, and thus a better understanding of its dispersal behavior may assist in developing improved management strategies. In order to investigateH. halysmovement and distribution patterns within a peach orchard we applied ecologically safe, food protein markers to the trees along the orchard border (chicken egg albumin in the form of liquid egg whites) and to the trees within the orchard interior (bovine casein in the form of cow’s milk). We used enzyme-linked immunosorbent assays (ELISA) to assess whether collectedH. halyswere “marked” with either of the two protein markers, revealing where in the orchard the bugs had visited. From the density data we determined thatH. halysis a perimeter-driven pest in peaches, with a significantly higher density of bugs collected along the orchard border. Interestingly, this trend is primarily driven by the distribution of male bugs. The protein marking data revealed that a small proportion of maleH. halysmove equally between the orchard border and interior, while a small proportion of females move predominately to the border after visiting the interior. The verification of a strong edge-effect, although potentially sex-specific, implies thatH. halysdisplays a dispersal behavior that may also be exploited for management, which may help growers more efficiently and more effectively manageH. halys.

We present in situ airborne measurements of methane (CH4) and ethane (C2H6) taken aboard a NOAA DHC‐6 Twin Otter research aircraft in May 2014 over the Williston Basin in northwestern North Dakota, a region of rapidly growing oil and natural gas production. The Williston Basin is best known for the Bakken shale formation, from which a significant increase in oil and gas extraction has occurred since 2009. We derive a CH4 emission rate from this region using airborne data by calculating the CH4 enhancement flux through the planetary boundary layer downwind of the region. We calculate CH4 emissions of (36 ± 13), (27 ± 13), (27 ± 12), (27 ± 12), and (25 ± 10) × 103 kg/h from five transects on 3 days in May 2014 downwind of the Bakken shale region of North Dakota. The average emission, (28 ± 5) × 103 kg/h, extrapolates to 0.25 ± 0.05 Tg/yr, which is significantly lower than a previous estimate of CH4 emissions from northwestern North Dakota and southeastern Saskatchewan using satellite remote sensing data. We attribute the majority of CH4 emissions in the region to oil and gas operations in the Bakken based on the similarity between atmospheric C2H6 to CH4 enhancement ratios and the composition of raw natural gas withdrawn from the region.
Black carbon mixing state impacts on cloud microphysical properties: Effects of aerosol plume and environmental conditions
Authors: Ching J. , Riemer N. , West M.
Published: May 2016

Black carbon (BC) is usually mixed with other aerosol species within individual aerosol particles. This mixture, along with the particles' size and morphology, determines the particles' optical and cloud condensation nuclei properties, and hence black carbon's climate impacts. In this study, the particle‐resolved aerosol model PartMC‐MOSAIC (Particle Monte Carlo‐Model for Simulating Aerosol Interactions and Chemistry) was used to quantify the importance of black carbon mixing state for predicting cloud microphysical quantities. Based on a set of about 100 cloud parcel simulations a process‐level analysis framework was developed to attribute the response in cloud microphysical properties to changes in the underlying aerosol population (“plume effect”) and the cloud parcel cooling rate (“parcel effect”). In most of the simulations the plume and parcel effects had opposite signs, with the plume effect dominating. The response of cloud droplet number concentration to changes in BC emissions depended on the BC mixing state. When the aerosol population contained mainly aged BC, an increase in BC emission increased cloud droplet number concentrations (“additive effect”). In contrast, when the aerosol population contained mainly fresh BC particles, they act as sinks for condensable gaseous species, resulting in decreasing cloud droplet number concentration as BC emissions were increased (“competition effect”). Additionally, we quantified the error in cloud microphysical quantities when neglecting the information on BC mixing state. The errors ranged from −12% to +45% for the cloud droplet number fraction, from 0% to +1022% for the nucleation‐scavenged BC mass fraction, from −12% to +4% for the effective radius, and from −30% to +60% for the relative dispersion.
Facial Wipes don't Wash: Facial Image Comparison by Video Superimposition Reduces the Accuracy of Face Matching Decisions
Authors: Strathie Ailsa , McNeill Allan
Published: May 2016

In cases of disputed CCTV identification, expert testimony based on the results of analysis by facial image comparison may be presented to the Jury. However, many of the techniques lack empirical data to support their use. Using a within‐participants design, we compared the accuracy of face‐matching decisions when images were presented using a ‘facial wipe’ technique (where one image is superimposed on another and the display gradually ‘wipes’ between the two) with decisions based on static images. Experiment 1 used high‐quality image pairs; Experiment 2 used disguised target images; and Experiment 3 used degraded target images. Across all three experiments, rather than optimising performance, facial wipes reduced accuracy relative to static presentations. Further, there is evidence that video wipes increase false positives and therefore may increase the likelihood that images of two different people will be incorrectly judged to show the same individual.Copyright © 2016 John Wiley & Sons, Ltd.
Site‐Selective Convergent Synthesis of Spiroacridines through a Cascade Reaction of Enaminones with Acenaphthoquinone: An Efficient Construction of Multiple C−C and C–Heteroatom Bonds
Authors: Chen Xue‐Bing , Wang Xue‐Quan , Hong Yong , Liu Wei
Published: May 2016

A highly efficient strategy has been developed for the regioselective synthesis of 9‐spiroacridine derivatives that have potential biochemical interest. The one‐pot cascade reaction of enaminones and acenaphthoquinone in the presence of para‐toluenesulfonic acid involved at least five reactive sites and generated two σ bonds, two types of C−N bonds, one stereocenter, and a dihydropyridine ring. The established protocol explores the chemistry of enaminones by employing its three reactive sites (i.e., N‐aryl nitrogen, β‐carbon, and C=O carbon atoms).

Published: May 2016

In Deutschland zeigen sich Infrastrukturbauwerke infolge Alterung und einer andauernden Steigerung des Schwerverkehrsaufkommens in zunehmend schlechterem Zustand. In diesem Zusammenhang kommt der Beurteilung der Resttragfähigkeit von Bauwerken besondere Bedeutung zu. Prognosen der (Rest‐) Lebensdauer können dazu einen entscheidenden Beitrag leisten. Am Lehrstuhl für Massivbau der Ruhr‐Universität Bochum wurde daher die Umsetzbarkeit einer Lebensdauerprognose an einem Bestandsbauwerk mithilfe von im Bauwesen verbreiteter Software untersucht.

Die Lebensdauerprognose basiert dabei auf der wiederholten nichtlinearen Berechnung der als FE‐Modell diskretisierten Struktur bis in den Grenzzustand der Tragfähigkeit. Nach Auswahl geeigneter Software wird das zu untersuchende Bauwerk in ein adäquates FE‐Modell überführt. Anschließend werden maßgebende Belastungen im Hinblick auf die am Bauwerk relevanten Schädigungsmechanismen identifiziert und modelliert. Es folgt die Vorstellung eines Verfahrens zur Lebensdauersimulation, in dem zunächst wesentliche Schädigungsprozesse sowie Streuungen und Unschärfen untersucht werden. Nach der Entwicklung eines Berechnungsalgorithmus und dessen Verifikation am Kleinbeispiel wird das Simulationskonzept auf das untersuchte Bestandsbauwerk übertragen. Eine Auswertung der Simulationsergebnisse identifiziert schlussendlich die maßgebenden Wirkungsmechanismen und belegt die Funktionsfähigkeit des entwickelten Simulationskonzepts.

Structural life‐time assessment employing well‐established engineering software

Currently Germany's infrastructure shows a progressively downgraded state of preservation due to aging along with an always increasing number of heavy good transports on the roads. In this context also the remaining bearing capacities of bridges gain rising importance. For an assessment lifetime prognoses can be very helpful. Therefore, an implementation of structural lifetime‐simulations employing commercial software has been developed at the institute of concrete structures of the Ruhr‐Universität Bochum. The concept is now proven by application to an existing pre‐stressed concrete bridge.

Generally, structural lifetime prognoses are based on repeated nonlinear simulation of a discretized bridge structure by finite elements up to the ultimate limit state. Once, appropriate software is chosen with respect to the simulation demands previously defined, the reference bridge is idealized by finite elements. Relevant load scenarios in view of pivotal damage mechanisms are identified and consequently set up. Next, the concept of structural lifetime simulation accounting for relevant damage mechanisms and imprecise input data is introduced briefly. A suited computational algorithm is developed and verified in a test case. Subsequently the concept is transferred to the reference bridge. Post‐processing of the simulation results identifies the relevant working principles and proves practical abilities of the simulation concept.

Published: May 2016

Anti‐cytotoxic T lymphocyte‐associated antigen‐4 (CTLA‐4) and anti‐programmed cell death‐1 (PD‐1) inhibitors have been shown to significantly improve survival in patients with metastatic cutaneous melanoma. However, there was some heterogeneity as well as some variation in the degree of benefit across studies. We reviewed randomized trials and performed a meta‐analysis to determine the efficacy and safety of immune checkpoint inhibitors in comparison with conventional regimens. Eligible studies were limited to randomized controlled trials comparing anti‐CTLA‐4 or anti‐PD‐1 inhibitors to chemotherapy or vaccination treatment in adult patients with unresectable cutaneous metastatic melanoma. Progression‐free survival (PFS) rate at 6 months was 28.5% versus 17.7% (RR: 0.84, 95% CI: 0.76–0.93), overall survival (OS) rate at 1 year was 51.2% versus 38.8% (RR: 0.72, 95% CI: 0.59–0.88), and overall response rate (ORR) at 6 months was 29.6% versus 17.7% (RR: 0.85, 95% CI: 0.76–0.95) favoring immune check point inhibitors over chemotherapies or vaccination. Immune check point inhibitors were associated with more frequent immune‐related adverse events at 13.7% versus 2.4% of treated patients (RR: 6.74, 95% CI: 4.65–9.75). Subgroup analyses demonstrated significant PFS (RR: 0.92 vs. 0.74, P < 0.00001) and ORR (RR: 0.95 vs. 0.76, P = 0.0004) improvement with anti‐PD‐1 treatment compared to anti‐CTLA‐4 when each of them was compared to control treatments. Collectively, these results demonstrate that immune checkpoint inhibitors have superior outcomes compared to conventional chemotherapies or vaccination, and support the results of recent randomized trials that showed superior outcomes with anti‐PD‐1 agents over ipilimumab in unresectable metastatic cutaneous melanoma patients.

Predictable behavior during contact simulation: a comparison of selected physics engines
Authors: Chung Se‐Joon , Pollard Nancy
Published: May 2016

Contact behaviors in physics simulations are important for real‐time interactive applications, especially in virtual reality applications where user's body parts are tracked and interact with the environment via contact. For these contact simulations, it is ideal to have small changes in initial condition yield predictable changes in the output. Predictable simulation is key for success in iterative learning processes as well, such as learning controllers for manipulations or locomotion tasks. Here, we present an extensive comparison of contact simulations using Bullet Physics, Dynamic Animation and Robotics Toolkit (DART), MuJoCo, and Open Dynamics Engine, with a focus on predictability of behavior. We first tune each engine to match an analytical solution as closely as possible and then compare the results for a more complex simulation. We found that in the commonly available physics engines, small changes in initial condition can sometimes induce different sequences of contact events to occur and ultimately lead to a vastly different result. Our results confirmed that parameter settings do matter a great deal and suggest that there may be a trade‐off between accuracy and predictability. Copyright © 2016 John Wiley & Sons, Ltd.
Synthesis of Cholesterol‐Substituted Glycopeptides for Tailor‐Made Glycocalyxification of Artificial Membrane Systems
Authors: Stuhr‐Hansen Nicolai , Madl Josef , Villringer Sarah , Aili Ulrika , Römer Winfried , Blixt Ola
Published: May 2016

Synthetic minimal membrane systems are extremely useful for better understanding of complex cellular structures and cell surface processes. We have developed a facile method for synthesis of cholesterylated peptides, each bearing a carbohydrate moiety and a fluorescent tag. The position of the cholesterol moiety on the peptide can be controlled by using a new Fmoc‐protected cholesterol‐triazole‐lysine group, which we constructed by means of solid‐phase peptide synthesis. We succeeded in integrating the glyco modules into giant unilamellar vesicles by electroformation or infusion in buffer solution. The glyco‐decorated liposomes were recognized by a lectin and had unique topological membrane features. In conclusion, this work is a proof of principle for the functionalization of artificial membranes with a primitive synthetic glycocalyx useful for studying carbohydrate–protein interactions on a simplified cell‐like membrane surface.

Influence of Carbon on Molybdenum Carbide Catalysts for the Hydrogen Evolution Reaction
Authors: Tang Chaoyun , Wu Zhuangzhi , Wang Dezhi
Published: May 2016

The influence of carbon on molybdenum carbide catalysts for the hydrogen evolution reaction (HER) is discussed. The carbon content is adjusted by varying the molar ratio of molybdenum and glucose sources and the holding time in the carbonization process. The carbon plays a crucial role in the determination of phase formation, surface area, and electrical resistance, which are associated with the final HER activity. There is a contradiction between the reduced active sites and improved electrical resistance that results from the reduced content of carbon, and a balance can be achieved with a holding time of 9 h to provide the best HER activity with a low Tafel slope of 55 mV dec−1 and a high exchange current density of 0.047 mA cm−2. Importantly, the transformation of the order of the free carbon improves the electrical conductivity remarkably to result in a great improvement in the final HER activity.
Reductive Depolymerization of Kraft and Organosolv Lignin in Supercritical Acetone for Chemicals and Materials
Authors: Yuan Zhongshun , Tymchyshyn Matthew , Xu Chunbao (Charles)
Published: May 2016

Kraft and organosolv lignin (KL and OL) were depolymerised efficiently in supercritical acetone in the presence of various hydrogenation catalysts (supported metal, e.g., Ni, Ru, Mo, W) and 100 bar hydrogen in the temperature range of 250–350 °C. Under the optimal conditions with Ru/C or FHUDS‐2 catalysts at 350 °C for 1 h, the yield of depolymerised Kraft lignin (DKL) or depolymerised organosolv lignin (DOL) was over 95 wt %. The weight average molecular weight of the lignin was reduced significantly from 10 200 (for KL) to 1020 g mol−1 (DKL) and from 2600 (OL) to 900 g mol−1 (DOL). The oxygen and sulfur contents of Kraft lignin were reduced by 24 and 96 %, respectively. The reductive depolymerisation treatment also decreased the amount of aliphatic hydroxyl groups and increased the amount of aromatic hydroxyl groups in the depolymerised lignin products.
