AbstractThis work investigates the feasibility of using an earth‐abundant and eco‐friendly Cu0.78Sn0.12Mn0.1Ox thin film as a catalyst for photodegradation applications under visible light. The thin film was deposited by e‐beam evaporation using the pallet formed using CuO, SnO2, and MnO2 powders as raw materials. The photocurrent response and performance as a catalyst of Methyl Orange (MO) dye photodegradation was optimized by varying the oxide composition to tune band gap and the use of post‐annealing at 500 °C for 3 hr in air to obtain crystalline structure of Cu0.78Sn0.12Mn0.1Ox thin films for higher photoconductivity. The band gap, conduction band energy level, and valence band energy level of the crystalline Cu0.78Sn0.12Mn0.1Ox oxide thin film were characterized to be 2.3 eV, −4.4 eV and −6.7 eV to vacuum, respectively. The stable photocurrent response with an intensity of ∼42 uA/cm2 at an applied voltage of −0.4 V under filtered 150 W Xe‐lamp visible light illumination could be achieved, which is higher than previous works even with lower power and thinner materials. Besides, the feasibility of Cu0.78Sn0.12Mn0.1Ox thin film for MO photodegradation under the visible light has also been demonstrated, though the rate constant still needs further improvement.

AbstractThe effective heterogeneous base catalysts are synthesized to intensify the catalytic capacity of dolomite via the wet impregnation method with NaAlO2. Compared with the calcined natural dolomite, the catalyst promoted by 10% NaAlO2 possesses the higher basic density and more developed mesoporous structure, where the better catalytic activity is performed to transesterify palm oil with methanol. Response surface methodology with Box‐Behnken Design (RSM‐BBD) is used to investigate the combined effects of the catalyst loaded amount, molar ratio of methanol to oil, transesterification temperature and duration on biodiesel yield. Results show that the highest yield of 99.27% is achieved with the 5.30 wt.% catalyst loaded amount and 12.39 molar ratio of methanol to oil at 65.26 °C for 2.11 h. The catalyst shows superior stability and efficiency of 89.92% is achieved for the fifth reused cycle, where for the pure calcined dolomite it is 77.58%. Also, the physicochemical indices of the purified transesterification product are in accordance with ASTM D6751 standard.

AbstractTo construct “non‐consumable electrolyte type” or “internal serial hybrid type” lithium‐ion supercapatteries with both high power and energy densities, carbon‐coated lithium vanadium phosphate composite (Li3V2(PO4)3/C) is utilized as the cathode. This cathode with a high specific area is synthesized by a hydrothermal method assisted by delayed sol‐gel method and using the surfactant of myristyltrimethylammonium bromide as the carbon source. It is self‐assembled and mesoporous. This cathode has a high specific surface area of 40.92 m2 g−1, a pore volume of 0.095 cm3 g−1, a considerably high initial discharge capacity of 166 mAh g−1 at 0.2 C‐rate. Even at 20 C‐rate, the high discharge capacity of 90 mAh g−1 is maintained. The lithium‐ion supercapattery assembled using this cathode, the anode of activated carbon as exhibits a discharge time of as long as 1369.24 s, a maximum energy density of 53.22 Wh kg−1, and a maximum power density of 3.01 kW kg−1. Such lithium‐ion supercapatteries thus overcome the disadvantages of rapid energy density attenuation under high power density of existed lithium‐ion supercapatteries.

SummaryProvenance is information about the origin and creation of data. In data science and engineering related with cloud environment, such information is useful and sometimes even critical. In data analytics, it is necessary for making data‐driven decisions to trace back history and reproduce final or intermediate results, even to tune models and adjust parameters in a real‐time fashion. Particularly, in cloud, users need to evaluate data and pipeline trustworthiness. In this paper, we propose a solution: LogProv, toward realizing these functionalities for big data provenance, which needs to renovate data pipelines or some of big data software infrastructure to generate structured logs for pipeline events, and then stores data and logs separately in cloud space. The data are explicitly linked to the logs, which implicitly record pipeline semantics. Semantic information can be retrieved from the logs easily since they are well defined and structured beforehand. We implemented and deployed LogProv in Nectar Cloud,* associated with Apache Pig, Hadoop ecosystem, and adopted Elasticsearch to provide query service. LogProv was evaluated and empirically case studied. The results show that LogProv is efficient since the performance overhead is no more than 10%; the query can be responded within 1 second; the trustworthiness is marked clearly; and there is no impact on the data processing logic of original pipelines.
Difference in the reaction process of slag activated by waterglass solution and NaOH solution

Published: September 2019

AbstractThe reaction processes of waterglass‐activated slag (WAS) and NaOH‐activated slag (NAS) with a high liquid‐to‐solid ratio were observed by using in‐situ polarization microscope. During these processes, the phase evolution in the alkali‐activated slag (AAS) was analyzed non‐destructively by means of X‐ray diffraction and scanning electron microscope (SEM). In parallel, hardened pastes of AAS were prepared and investigated by means of SEM and mercury intrusion porosimetry. The results showed that the reaction of NAS was dissolution‐precipitation process at the early age, and the reaction products tended to form around or on the surface of slag particles. A few kinds of intermediate products, such as Ca[OH]2, were formed at the beginning. At the later age, the reaction mechanism of NAS changed into solid‐phase reaction, and the reaction products tended to generate in the space that originally occupied by the slag particles. In comparison, the whole process of the reaction between waterglass and slag was dissolution‐precipitation under the condition of a high liquid‐to‐solid ratio. The reaction products tended to form in the solution, which was beneficial for pore‐filling. The aforementioned difference in reaction process made the hardened paste of NAS had a higher porosity and a lower early strength than the hardened paste of WAS.

ABSTRACTObjectiveThe Hypertension and Preeclampsia Intervention Trial At near Term‐I (HYPITAT‐I) randomized controlled trial showed that, in women with gestational hypertension or mild pre‐eclampsia at term, induction of labor, compared with expectant management, was associated with improved maternal outcome without compromising neonatal outcome. The aim of the current study was to evaluate the impact of these findings on obstetric management and maternal and perinatal outcomes in The Netherlands.MethodsWe retrieved data for the period 2000–2014 from the Dutch National Perinatal Registry, including 143 749 women with gestational hypertension or pre‐eclampsia and a singleton fetus in cephalic presentation, delivered between 36 + 0 and 40 + 6 weeks of gestation (hypertensive disorder of pregnancy (HDP) group). Pregnant women without HDP were used as the reference group (n = 1 649 510). The HYPITAT‐I trial was conducted between 2005 and 2008. To study the impact of HYPITAT‐I, we compared rate of induction of labor, mode of delivery and maternal and perinatal outcomes in the periods before (2000–2005) and after (2008–2014) the trial. We also differentiated between hospitals that participated in HYPITAT‐I and those that did not.ResultsIn the HDP group, the rate of induction of labor increased from 51.1% before the HYPITAT‐I trial to 64.2% after it (relative risk (RR), 1.26; 95% CI, 1.24–1.27). Maternal mortality decreased from 0.022% before the trial to 0.004% after it (RR, 0.20; 95% CI, 0.06–0.70) and perinatal death decreased from 0.49% to 0.27% (RR, 0.54; 95% CI, 0.45–0.65), which was attributable mostly to a decrease in fetal death. Both the increase in induction rate and the reduction in hypertensive complications were more pronounced in hospitals that participated in the HYPITAT‐I trial than in those that did not. Following HYPITAT‐I, the rate of induction of labor also increased (by 4.6 percentage points) in the reference group; however, the relative increase in the HDP group (13.1 percentage points) was significantly greater (P < 0.001 for the interaction). The reduction in maternal and perinatal deaths did not differ significantly between the HDP and reference groups. There was a decreased incidence of placental abruption in both HDP and reference groups, which was significantly greater in the HDP than in the reference group (P < 0.001 for the interaction). There was also an increased incidence of emergency Cesarean section in both HDP and reference groups; however, this change was significantly greater in the reference than in the HDP group (P < 0.001 for the interaction).ConclusionFollowing the HYPITAT‐I trial, there was a higher rate of induction of labor and improved obstetric outcome in term pregnancies complicated by HDP in The Netherlands.

Published: September 2019

ABSTRACTObjectiveTo report the outcome of monochorionic twins with twin reversed arterial perfusion (TRAP) sequence following interstitial laser therapy in the first trimester.MethodsThis was a retrospective cohort study of all consecutive cases of TRAP that underwent interstitial laser therapy at ≤ 14 + 3 weeks' gestation between January 2014 and April 2016. Interstitial laser treatment was performed under ultrasound guidance using a 400‐nm Nd:YAG laser fiber. Hospital records were reviewed to ascertain perinatal survival and morbidity.ResultsTwelve monochorionic twin pregnancies underwent interstitial laser treatment of the umbilical artery of the acardiac fetus, at a median gestational age of 13 + 5 (interquartile range (IQR), 13 + 4 to 14 + 0) weeks. In all cases, one treatment was sufficient to achieve complete interruption of the perfusion of the acardiac twin. There were no procedure‐related complications during or within 48 h after the procedure. In one (8.3%) case, intrauterine death of the pump twin occurred 2 weeks after the intervention. All other cases (91.7%) resulted in a live birth at a median gestational age of 39 + 6 (IQR, 37 + 1 to 41 + 2) weeks and with a median birth weight of 3370 (IQR, 2980–3480) g. No neonatal mortality or serious morbidity occurred.ConclusionsOur results support the use of interstitial laser therapy in the first trimester of pregnancy complicated by TRAP sequence, showing a live birth rate of 92%. The results of a randomized controlled trial, evaluating early vs late intervention in pregnancy with TRAP sequence, are awaited. © 2019 The Authors.

Plant molecular farming of virus‐like nanoparticles as vaccines and reagents
Authors: Rybicki Edward P. 
Published: September 2019

AbstractThe use of plants for the production of virus‐like nanoparticles (VNPs) dates back to separating natural empty capsids of plant viruses from whole virions nearly 70 years ago, through to the present use of transgenic plants or recombinant Agrobacterium tumefaciens and/or plant virus‐derived vectors for the transient expression of engineered viral or other structural proteins in plants—a production system also known as molecular farming. Plant production of heterologous proteins has major advantages in terms of convenience—whole plants are generally used, and processes do not need to be sterile—and cost, as bulk biomass production is significantly cheaper than by any other method. Plant‐made VNPs in current use for nanotechnology include whole virions and naturally occurring empty capsids of plant viruses, and particles made by reassembly of coat protein (CP) purified from virions or by recombinant expression. Engineered VNP‐forming animal or human virus CPs expressed in plants include L1 protein from human papillomaviruses, human norovirus CP, hepatitis B surface and core antigens, influenza virus HA protein and HIV Gag polyprotein forming large enveloped particles by budding, orbi‐ and rotavirus particles that require assembly of four co‐expressed proteins, and polio‐ and foot and mouth disease viruses which require proteolytic processing of a polyprotein precursor to form 4‐component VNPs. Both plant and animal virus‐derived plant‐made VNPs can be used for surface and internal display of heterologous peptides or even whole proteins. A significant recent development has been the production of pseudovirions in plants, comprising plant or animal virus CPs and RNA or DNA pseudogenomes that can be used to deliver nucleic acid payloads into cultured cells or specific tissues or tumors in whole animals.This article is characterized under:Biology‐Inspired Nanomaterials > Protein and Virus‐Based StructuresTherapeutic Approaches and Drug Discovery > Emerging TechnologiesDiagnostic Tools > in vivo Nanodiagnostics and Imaging
Influence of the federal landowner Incentive Program

Published: September 2019

ABSTRACTThe Landowner Incentive Program (LIP) was introduced as a federal conservation program administered by the U.S. Fish and Wildlife Service in 2002 as a means to incentivize private landowners in the management of rare wildlife species and their habitats. States and tribes were encouraged to apply for competitive funding and establish appropriate programs aimed at reversing population declines of wildlife species on privately owned land. We document the origin of LIP and highlight 2 case studies that exemplify innovations catalyzed by LIP. From 2002 to 2007, US$127 million was appropriated and >4,300 projects were completed nationwide. © 2019 The Wildlife Society.
A state assessment of private lands wildlife conservation in the United States
Authors: Morgan John J. , Rhoden Cody M. , White Bill , Riley Steven P. 
Published: September 2019

ABSTRACTWildlife habitat in the United States is largely owned by private entities. Threatened and endangered species conservation and game‐species hunting interests occur predominately on private lands. Our wildlife conservation history was characterized by eras of exploitation followed by conservation reactions. State wildlife agencies evolved through those eras as well. We sought to assess state wildlife agency investments in private lands conservation. We used a short survey to construct an index score designed to measure the state agency manpower commitment (%) as it relates to the composition of the state's private ownership (%). During 2019, we collected data about state wildlife agency participation in private lands program activities including cost‐share, equipment loans, or free supplies (seed or herbicide). Our survey metrics showed Kansas, USA, was the national leader in its commitment to private land management. Several midwestern and western states were notably well‐positioned to deliver private lands conservation relative to the nation. Our data show states are trending toward more effort on privately owned lands, but they continue to focus disproportionately more manpower on publicly owned lands or other priorities. Development of state wildlife agency commitments to private lands is a process characterized well by the Missouri Department of Conservation, USA. Expansion in conservation efforts on private lands will likely be linked to funding expansion that includes nonconsumptive users. We charge professionals to meet the conservation challenges of the 21st Century, they must invest significantly greater resources in private lands management through state wildlife agencies. © 2019 The Wildlife Society.
Development of an Algorithm for Optimal Demand Responsive Relocatable Feeder Transit Networks Serving Multiple Trains and Stations
Authors: Lee Young-Jae , Meskar Mana , Nickkar Amirreza , Sahebi Sina 
Published: September 2019

AbstractAlthough demand responsive feeder bus operation is possible with human-driven vehicles, it has not been very popular and is mostly available as a special service because of its high operating costs due to intensive labor costs as well as requirement for advanced real-time information technology and complicated operation. However, once automated vehicles become available, small-sized flexible door-to-door feeder bus operation will become more realistic, so preparing for such automated flexible feeder services is necessary to take advantage of the rapid improvement of automated vehicle technology. Therefore, in this research, an algorithm for optimal flexible feeder bus routing, which considers relocation of buses for multiple stations and trains, was developed using a simulated annealing algorithm for future automated vehicle operation. An example was developed and tested to demonstrate the developed algorithm. The algorithm successfully handled relocation of buses when the optimal bus routings were not feasible using the buses available at certain stations. Furthermore, the developed algorithm limited the maximum degree of circuity for each passenger while minimizing the total cost, including total vehicle operating costs and total passenger in-vehicle travel time costs.
A model of identity development: Life‐course narratives of North Korean youth resettling in South Korea
Authors: Park Heejung 
Published: September 2019

ABSTRACTIntroductionIdentity development is a convoluted process for youth experiencing traumatic interruptions in their lives. This study aimed to build a model of identity development in an understudied cultural group of trauma‐exposed youth who fled North Korea and resettled in South Korea.MethodsSixteen participants (75% female, Mage = 26.63 years, Mdefection age = 16.29 years, Mdefection duration = 5.72 years) produced life‐course narratives, as guided by the life‐lines they drew to depict their high and low points and future trajectories. The cross‐sectional qualitative data were analyzed using thematic content analysis. Themes of identity, trauma, and turning points were derived and coded, and then organized sequentially to classify stages of identity development.ResultsThe Vulnerable stage defined a sense of helplessness during an early life of deprivation in North Korea. Their identity entered the Invisible stage during their hiding in China. Upon reaching South Korea, they traversed four stages: The Renewal stage signaling a fresh outset; the Turmoil stage characterized by acculturative stress, rejection, and family disruption; the Achieved stage of relative stability; and the Self‐Transcendence stage in which youth extended beyond their immediate views of self and focused on meaning and purpose across the themes of social change, reconciliation, and spirituality.DiscussionThe six‐stage model of identity development demonstrates that North Korean youth who defect to South Korea undergo a multifaceted identity development process as they navigate adversities, interruptions, and turning points. Results suggest that traumatic experiences can spur positive identity development and provide implications for professionals working with youth affected by intense and prolonged social conflict.
Medial Temporal Lobe Dysgenesis and More in a Man with Hypochondroplasia and Epilepsy
Authors: Krawitz S , Del Bigio M 
Published: September 2019

Hypochondroplasia, achondroplasia, and thanatophoric dysplasia are related at the molecular level, all caused by fibroblast growth factor receptor 3 (FGFR3) gene mutations. They differ in severity. FGFR3 has critical roles in fibroblast growth factor (FGF) signalling pathways during bone growth and cerebral cortical development. Mutations of the FGFR3 gene lead to constitutive activation of FGFR3. The well-described brain malformation in thanatophoric dysplasia is characterized by gross abnormalities of temporal lobe patterning and severe dysplasia of the hippocampus. Experimental models suggest that increased proliferation, abnormal migration, and decreased apoptosis are involved. However, reports of the brain findings in hypochondroplasia are based solely on radiologic imaging.We present the neuropathology of a 44 year-old man with hypochondroplasia, epilepsy, and significant intellectual disability. The temporal lobes are enlarged, prominent fissures traverse the inferior temporal surface, and the hippocampus is abnormally folded. Microscopically, the dentate gyrus is variably small or thin and is located near the edge of a gyrus. Ammon’s horn is displaced and meandering. Subicular-like clusters are profuse. Complex gyri resemble microgyria. White matter forms a subpial border in some gyri. In summary: medial temporal lobe dysgenesis.This individual also had many autistic features including stereotypies and head banging. The latter could explain another surprising set of brain abnormalities unrelated to the presumed FGFR3-related syndrome.LEARNING OBJECTIVESThis presentation will enable the learner to:1.Summarize current theories on the pathogenesis of FGFR3-related cortical malformation2.Describe the brain abnormalities in hypochondroplasia3.Identify the neuropathology resulting from head banging
