Doveweed (Murdannia nudiflora) response to metsulfuron-methyl, trifloxysulfuron-sodium, and bentazon combinations
Authors: Sharpe Shaun M. , Boyd Nathan S.
Published: October 2019

Doveweed is a problematic weed species in many agricultural ecosystems as well as on roadsides and rights-of-way. Effective POST chemical control options for doveweed are limited in many cropping systems. Greenhouse studies were conducted to evaluate the effectiveness of metsulfuron-methyl dose and the impact of mixtures and sequential applications of either trifloxysulfuron-sodium or bentazon with metsulfuron-methyl for doveweed control. By 14 d after the initial treatment, applying 0.04 kg ai ha−1 metsulfuron-methyl, either once or sequentially, provided 100% control of doveweed. Application of trifloxysulfuron-sodium at 0.04 kg ai ha−1 alone or in mixture with metsulfuron-methyl (0.04 kg ha−1) did not provide consistent doveweed control nor did it reduce biomass. Trifloxysulfuron-sodium applied alone at 0.08 kg ha−1 or in a mixture with metsulfuron-methyl (0.04 kg ha−1) provided consistent doveweed control (>80%). A single application of bentazon (0.56 kg ai ha−1) was ineffective at controlling doveweed. A single application of the bentazon and metsulfuron-methyl mixture (0.56 + 0.04 kg ha−1, respectively) or sequential applications of either bentazon alone (0.56 kg ha−1) or in mixture with metsulfuron-methyl (0.04 kg ha−1) provided excellent doveweed control (100%) by 35 d after treatment. Overall, single applications of metsulfuron-methyl (0.02 to 0.17 kg ha−1) or mixtures of metsulfuron-methyl with trifloxysulfuron-sodium (0.04 + 0.08 kg ha−1, respectively) or bentazon (0.04 + 0.56 kg ha−1, respectively) controlled doveweed and may be useful for enhancing the control spectrum for other weeds. Sequential applications of the bentazon and metsulfuron-methyl mixture (0.56 + 0.04 kg ha−1, respectively) provided doveweed control and are a resistance-management strategy for doveweed.

Published: October 2019

Southern crabgrass [Digitaria ciliaris (Retz.) Koeler] is an annual grass weed that commonly infests turfgrass, roadsides, wastelands, and cropping systems throughout the southeastern United States. Two biotypes of D. ciliaris (R1 and R2) with known resistance to cyclohexanediones (DIMs) and aryloxyphenoxypropionates (FOPs) previously collected from sod production fields in Georgia were compared with a separate susceptible biotype (S) collected from Alabama for the responses to pinoxaden and to explore the possible mechanisms of resistance. Increasing rates of pinoxaden (0.1 to 23.5 kg ha−1) were evaluated for control of R1, R2, and S. The resistant biotypes, R1 and R2, were resistant to pinoxaden relative to S. The S biotype was completely controlled at rates of 11.8 and 23.5 kg ha−1, resulting in no aboveground biomass at 14 d after treatment. Pinoxaden rates at which tiller length and aboveground biomass would be reduced 50% (I50) and 90% (I90) for R1, R2, and S ranged from 7.2 to 13.2 kg ha−1, 6.9 to 8.6 kg ha−1, and 0.7 to 2.1 kg ha−1, respectively, for tiller length, and 7.7 to 10.2 kg ha−1, 7.2 to 7.9 kg ha−1, and 1.6 to 2.3 kg ha−1, respectively, for aboveground biomass. Prior selection pressure from DIM and FOP herbicides could result in the evolution of D. ciliaris cross-resistance to pinoxaden herbicides. Amplification of the carboxyl-transferase domain of the plastidic ACCase by standard PCR identified a point mutation resulting in an Ile-1781-Leu amino acid substitution only for the resistant biotype, R1. Further cloning of PCR product surrounding the 1781 region yielded two distinct ACCase gene sequences, Ile-1781 and Leu-1781. The amino acid substitution, Ile-1781-Leu in both resistant biotypes (R1 and R2), however, was revealed by next-generation sequencing of RNA using Illumina platform. A point mutation in the Ile-1781 codon leading to herbicide insensitivity in the ACCase enzyme has been previously reported in other grass species. Our research confirms that the Ile-1781-Leu substitution is present in pinoxaden-resistant D. ciliaris.
A 391‐Year Summer Temperature Reconstruction of the Tien Shan, Reveals Far‐Reaching Summer Temperature Signals Over the Midlatitude Eurasian Continent
Authors: Chen Feng , Yuan Yujiang , Yu Shulong , Chen Fahu
Published: October 2019

The Tien Shan is the largest independent latitudinal mountain ranges in Eurasia, but due to a lack of long‐term instrumental data, knowledge of past temperature variability in the Tien Shan is limited. In this paper, a maximum latewood density (MXD) chronology of Schrenk spruce (Picea schrenkiana) was constructed from the Tien Shan, Central Asia. Correlation analyses indicate that the MXD variations of spruce trees in the Tien Shan are mainly limited by summer temperature variations. The July–August mean temperature was reconstructed for the Tien Shan back to 1615 CE. The temperature reconstruction explained 42.9% of the instrumental variance (1930–2005). This reconstruction successfully captured the past temperature variabilities in the Tien Shan and enabled visualization of the cool climate before 1850s and the climatic warming after the 1850s. Agreement among the temperature series of the Tien Shan and regional temperature records based on MXDs from Eurasia suggested that our reconstruction had good reliability, captured some warm/cold periods, and first principal component of these MXD records showed that there are strong large‐scale temperature forcings in Eurasia. Our study also showed that there is a linkage between temperature changes in Central Asia and the atmospheric circulations of the middle‐high latitude westerly region and the sea surface temperatures of both the Pacific Ocean and the Atlantic Ocean. The positive correlations among the principal component time series of regional temperature reconstructions based on MXDs and Northern Hemisphere temperature reconstructions revealed that the MXD chronologies from Central Asia have the potential for developing large‐scale temperature reconstruction.
Ice Core δ18O Record Linked to Western Arctic Sea Ice Variability
Authors: Porter Stacy E. , Mosley‐Thompson Ellen , Thompson Lonnie G.
Published: October 2019

Stable oxygen isotopes (δ18O) in the Bona‐Churchill (B‐C) ice core from southeast Alaska provide a valuable, high‐resolution history of climate variability and sea ice cover in the western Arctic over the last 800 years. Multiple ice cores have been collected from the Wrangell‐St. Elias Mountain Range; however, their δ18O records exhibit little consistency as each core offers a unique view on local, regional, and/or global climate variability. To explore the primary mechanisms influencing the isotopic signature at the B‐C site, we utilize isotope‐enabled model data, reanalysis data, and observations, which all indicate a strong connection between isotopes at the B‐C site and western Arctic climate, likely established by the location of the storm track in this region. Enriched B‐C δ18O reflects increased southerly flow and warmer waters in the Bering Sea, which modulates the heat flux through the Bering Strait and into the Arctic, thereby affecting sea ice cover in the western Arctic. The B‐C δ18O paleorecord shares some remarkable similarities (r = −0.80, p < .001) with the duration of western arctic sea ice cover reconstructed from a Chukchi Sea sediment core. Interestingly, during the Little Ice Age, enriched δ18O and reduced western Arctic sea ice are observed and may be indicative of prolonged periods of the warm Arctic/cold continents pattern and a northwestward shift of the North Pacific storm track.
Street‐Scale Mapping of Urban Radio Frequency Noise at Very High Frequency and Ultra High Frequency
Authors: Breton Daniel J. , Haedrich Caitlin E. , Kamrath Matthew J. , Wilson D. Keith
Published: October 2019

Modern measurement campaigns of man‐made radio frequency (RF) noise have reported results from fixed locations that are assumed to be representative of the surroundings. Models derived from these measurements include parameters to express the variability in time and in space over very large distances (i.e., differences between cities). Despite the rapidly evolving mixture of noise sources, especially in modern urban environments, spatial variation of RF noise power at the scale of streets and blocks is essentially unknown in the very high frequency and ultra high frequency bands. Using a portable calibrated noise measurement system of our design, RF noise was recorded over a 1‐MHz bandwidth for frequencies of 142.0, 246.5, and 972 MHz. Noise surveys were conducted during daytime working hours in two different neighborhoods within Boston, Massachusetts, USA, with each survey transiting a fixed, several kilometer long route, repeated twice to enable separation of temporal from spatial variability. Significant and spatially repeatable variations in median power, peak power, and voltage deviation were observed over distances of tens to hundreds of meters, dependent upon the measurement frequency. The observed spatial patterns of median and peak power appear to be repeatable on timescales of hours to weeks, and likely beyond, suggesting that these noise patterns are persistent features of the urban environment.

Resolution of bacterial infections is often hampered by both resistance to conventional antibiotic therapy and hiding of bacterial cells inside biofilms, warranting the development of innovative therapeutic strategies. Here, we report the efficacy of blue laser light in eradicating Pseudomonas aeruginosa cells, grown in planktonic state, agar plates and mature biofilms, both in vitro and in vivo, with minimal toxicity to mammalian cells and tissues. Results obtained using knock-out mutants point to oxidative stress as a relevant mechanism by which blue laser light exerts its anti-microbial effect. Finally, the therapeutic potential is confirmed in a mouse model of skin wound infection. Collectively, these data set blue laser phototherapy as an innovative approach to inhibit bacterial growth and biofilm formation, and thus as a realistic treatment option for superinfected wounds.

This study describes a simple, high-yield, rapid, and inexpensive route for the synthesis of cubic shape-like cerium oxide nanocubes (CeO2 NCs) using different urea concentrations (0.5, 1.0, and 2.0 g) by the hydrothermal method. The synthesized nanocubes (NCs) are labeled as CeO2 NCs-0.5, CeO2 NCs-1.0, and CeO2 NCs-2.0, corresponding to 0.5, 1.0, and 2.0 g of urea, respectively. The synthesized NCs were characterized by FT-IR, UV-visible, XRD, XPS, SEM and HR-TEM analysis. The synthesized NCs were cubic in shape with average sizes of 12, 12, and 13 nm for the CeO2 NCs-0.5, CeO2 NCs-1.0, and CeO2 NCs-2.0, respectively, obtained by the XRD analysis. The catalytic activity of the CeO2 NCs was studied for the purpose of obtaining the reduction of malachite green (MG) in the presence of sodium borohydride (NaBH4) at room temperature.

Published: October 2019

To effectively inhibit the growth of breast cancer cells (MDA-MB-231 cells) by the combination method of chemotherapy and magnetic hyperthermia, we fabricated a biomimetic drug delivery (CSiFePNs) system composed of mesoporous silica nanoparticles (MSNs) containing superparamagnetic ferroferric oxide and Paclitaxel (PTX) coated with MDA-MB-231 cell membranes (CMs). In the in vitro cytotoxicity tests, the MDA-MB-231 cells incubated with CSiFePNs obtained IC50 value of 0.8 μgL−1, 3.5-fold higher than that of SiFePNs. The combination method of chemotherapy and magnetic hyperthermia can effectively inhibit the growth of MDA-MB-231 cells.

Background Insulin degludec, an ultra-long-acting insulin analogue, has been available in Thailand since October 2016. Although clinical trial results revealed less hypoglycemia, data from real-world settings is limited especially in Asian patients. This study aimed to evaluate prospectively the real-world effectiveness, safety, quality of life (QOL) and patient satisfaction with insulin degludec among Thai patients with diabetes mellitus (DM).

Methods From October 2016 to September 2017, all patients who had started insulin degludec for at least 3 months were observed and evaluated at baseline, 3, 6, and 12 months. QOL was assessed using WHOQOL-BREF-THAI and level of satisfaction was measured by 7-point Likert scale. Glycemic fluctuation from paired iPro2 continuous glucose monitoring (CGM) obtained 4–6 weeks apart were also evaluated from a subset of patients with T1DM who switched from insulin glargine to insulin degludec.

Results A total of 55 patients (T2DM 76.4%, females 54.5%, mean age 57.1±16.1 years, duration of diabetes 16.7±8.8 years, BMI 27.3±5.5 kg/m2, baseline A1C 9.3±2.3%, median duration of treatment 8 months) were included in the study. In T1DM patients (n=13), the overall mean A1C reduction at 12 months was 0.5% with minimal weight gain of 0.9 kgs at 12 months. In T2DM patients (n=42), the overall mean A1C reduction at 12 months was 0.8% with minimal weight loss of 0.4 kgs at 12 months. The proportion of T1DM patients who could achieve optimal glycemic control increased slightly from 14.3 to 18.2% but the proportion of T2DM patients who could achieve optimal glycemic control increased from 30.8 to 53.8%. Patient satisfaction showed a sustained improvement throughout the duration of study. In four T1DM patients who had paired CGM data, insulin degludec provided greater reductions in glycemic variability endpoints with increased time-in-range when compared with previous insulin glargine.

Discussion Our data suggested that the effectiveness of insulin degludec was consistent with the results seen in clinical trials with lower risk of patients-reported hypoglycemia, and a significant improvement in glycemic control. Patients also reported higher treatment satisfaction. More long-term and cost-effectiveness data are needed to establish the role of this ultra-long-acting insulin in real-world settings.
New Perspectives for Modern Trauma Management – Lessons Learned from 25 Years FAST and 15 Years E-FAST
Authors: Osterwalder Joseph , Mathis Gebhard , Hoffmann Beatrice
Published: October 2019

E-FAST (Extended-Focused Assessment with Sonography for Trauma) is now a widely utilized and internationally recognized standard exam in trauma care. It is highly accepted by emergency physicians and trauma surgeons alike. Thanks to the popularity of PoCUS (point-of-care ultrasound), it has continued to evolve over the last years and can now improve trauma diagnosis at all stages of the primary ABCDE. This review article summarizes key observations made over recent years and also highlights the extension of FAST into E-FAST in the context of PoCUS and CT developments for modern trauma management. Time has come to learn the lessons from 25 years of FAST and 15 years of E-FAST. We should redefine and position ultrasound in the primary ATLS survey (Advanced Trauma Life Support) on two levels: 1. Basic ATLS with new clinical questions, six additional abdominal image sections and one or more follow-up examinations depending on the clinical situation, and 2. Advanced ATLS with ultrasound applications for the entire trauma ABCDE.

Published: October 2019

Ziel der Studie Brustkrebs beim Mann ist eine seltene Erkrankung,
für die jedoch hochspezialisierte Versorgungsstrukturen zur Therapie des
Brustkrebses der Frau zur Verfügung stehen. Bislang ist unbekannt, ob
die Ausrichtung der Versorgungsstrukturen auf Frauen zu Defiziten in der
Versorgung der betroffenen Männer führt. Daher ist es das Ziel
der vorliegenden Untersuchung, mögliche Versorgungsdefizite aus der
Perspektive der beteiligten Professionen zu identifizieren.

Methodik Es wurden teilstandardisierte Leitfadeninterviews mit
n=23 Teilnehmer/innen sowie 2 Fokusgruppendiskussionen mit
n=7 bzw. n=9 Teilnehmer/innen durchgeführt. Die
Transkripte der Interviews und Fokusgruppendiskussionen wurden mittels
qualitativer Inhaltsanalyse mit MAXQDA ausgewertet.

Ergebnisse Einige Teilnehmer/innen sehen aufgrund des
Erfahrungsmangels eigene Unsicherheiten in der Versorgung von Männern
mit Brustkrebs. Häufig wird ein mangelndes Wissen bezüglich der
Zuständigkeiten und Behandlungsmöglichkeiten, z. B. bei
niedergelassenen Gynäkolog/innen, beklagt. Viele Befragte
empfinden eine mangelnde interdisziplinäre Zusammenarbeit, v. a. in der
Nachsorge. Einige Befragte sehen darüber hinaus einen Mangel an
spezialisierten Rehabilitationseinrichtungen für Männer mit
Brustkrebs.

Schlussfolgerung Männer mit Brustkrebs profitieren trotz der
Seltenheit der Erkrankung von den hochentwickelten Strukturen zur
Brustkrebsversorgung in Deutschland. Dennoch zeigen sich Versorgungsdefizite aus
der Sicht der behandelnden Professionen. Diese Datengrundlage kann in
Kombination mit der Perspektive der Betroffenen und weiteren
repräsentativen Daten dazu dienen, Praxis-Empfehlungen zur Verbesserung
der Versorgungsqualität des männlichen Brustkrebses zu
erarbeiten.

Published: October 2019

Objective Sports-related injuries, such as facial fractures, are potentially debilitating and may lead to long-term functional and aesthetic deficits in a pediatric patient. In this study, we analyze sports-related facial fractures in the urban pediatric population in an effort to characterize patterns of injury and improve management strategies and outcomes.

Methods Retrospective chart review was performed for all facial fractures resulting from sports injuries in the pediatric population at a level-1 trauma center (University Hospital, Newark, NJ).

Results Seventeen pediatric patients were identified as having sustained a fracture of the facial skeleton due to sports injury. Mean age was 13.9 years old. A total of 29 fractures were identified. Most common fracture sites included the orbit (n = 12), mandible (n = 5), nasal bone (n = 5), and zygomaticomaxillary complex (n = 3). The most common concomitant injuries included skull fracture (n = 3), intracranial hemorrhage (n = 4), and traumatic brain injury (n = 4). One patient was intubated upon arrival to the emergency department. Hospital admission was required in 13 patients, 4 of which were admitted to an intensive care setting. Nine patients required operative intervention. Mean length of hospital stay was 2.4 days. No patients were expired.

Conclusions Sports-related facial fractures are potentially debilitating injuries in the pediatric population. Analysis of fracture pattern and concomitant injuries is imperative to develop effective management strategies and prevention techniques.

Published: October 2019

We report a 13-year-old boy who (initially) had symptoms of toxic shock-like syndrome and mumps. Then, the patient was hospitalized in the pediatric intensive care unit (PICU) because of his ongoing hemodynamic instability (low blood pressure of 70/30 mm Hg and capillary refill time of > 4 seconds). During his stay in the PICU, the patient was treated with fluid resuscitation and vasoactive infusion and at the same time was diagnosed with Kawasaki disease shock syndrome (KDSS), when giant right coronary artery aneurysms were detected on echocardiographic examination. This case illustrates the risk of KDSS in patient who carries both parotitis and toxic shock-like syndrome. The clinicians should be cautious about detecting any types of coronary artery aneurysms in such patients. This is the first case of KDSS associated with parotitis reported in the literature.
Venous Thrombosis in Acquired Hemophilia: The Complex Management of Competing Pathologies
Authors: Chhabra Manu , Hii Zhen Wan Stephanie , Rajendran Joseph , Ponnudurai Kuperan , Fan Bingwen Eugene
Published: October 2019

Introduction Venous thrombosis is rare in the setting of factor VIII (FVIII) deficiency. Cases of deep vein thrombosis (DVT) have been described in hemophiliacs after recent major surgery, or in association with the administration of FVIII concentrate and activated prothrombin complex concentrates, but occurrence of spontaneous DVT is even more uncommon.

Aim We describe the challenging management of extensive DVT in a patient with acquired hemophilia A with concurrent hemorrhagic manifestations and review similar published cases.

Methods We summarize a series of 10 cases with the following demographics: 6 males and 4 females; median age at presentation of 65 (21–80); mean inhibitor titer of 68.5 Bethesda Units (BU 1.9 to BU 350).

Results Four cases were idiopathic and six had associated conditions (cancer [two cases], recent pregnancy [two cases], and recent surgery [two cases]). Three cases had an inferior vena cava filter inserted for acute lower limb DVT/pulmonary embolism. Inhibitor eradication was achieved with high-dose steroids with or without cyclophosphamide, and adjunct Rituximab administration was used in three cases. One patient received concurrent therapeutic plasma exchange (TPE). Inhibitor eradication was fastest with concurrent TPE at 6 days (range: 6–733 days). The 30-day survival was 90%.

Conclusions There was adequate response of inhibitors to immunosuppression with steroids and cyclophosphamide therapy. For more refractory disease, Rituximab is emerging as a beneficial and cost-effective adjunct with better rates of complete remission, and the threshold for its use may be lowered in this complex cohort with dual competing pathologies.

Regulation of electron-hole recombination kinetics on uniform metal-semiconductor nanostructures for photocatalytic hydrogen evolution
Authors: Choi W. , Choi J. Y. , Song H.
Published: October 2019

Photocatalytic hydrogen evolution has garnered considerable attention as a potential technology for the conversion of solar energy to chemical energy to replace fossil fuels with the development of hydrogen energy infrastructure. Semiconductors have been intensively studied as photocatalysts due to their tunable bandgap, eco-friendly reaction mechanism, photochemical stability, and ease of reusability. To achieve highly efficient photocatalysts, regulation of exctions, which are photoinduced electrons and holes in photocatalysts, is necessary. Semiconductor nanoparticles have been applied in this purpose because of their confined exciton pathways and differentiated catalytic characteristics depending on their size, shape, and morphology. In addition, metal cocatalysts have been decorated with semiconductor nanoparticles because the metal cocatalyst not only provides efficient shuttling of photoinduced electrons and proper reaction sites for the hydrogen evolution but also controls exciton pathways via fast electron transfer kinetics from semiconductor to metal. This research update reviews recent advances in representative metal-semiconductor hybrid nanostructures of core-shell and tipped nanorods for photocatalysts with a focus on the exciton pathways. The metal at semiconductor core-shell nanostructures has shown extraordinary photocatalytic stability via passivation of the metal by a semiconductor. In photocatalytic hydrogen evolution, the semiconductor shell hinders electron transfer to water. Hence, various core-shell related metal-semiconductor nanostructures such as yolk-shell, core-island shell, and double shell hollow structures have been proposed in efforts to overcome the electron transfer barrier to water. Metal tipped nanorods are another versatile nanostructure to control and monitor exciton pathways. The correlation between exciton pathways and photocatalytic efficiencies was demonstrated by monitoring metal tipped semiconductor nanorods with different composition, morphology, and surface structure. The insights reported here suggest a rational and versatile design strategy of metal-semiconductor hybrid nanostructures for developing highly efficient photocatalysts for hydrogen evolution.

The effect of magnetic force on nonlinear energy harvesting performance is discussed theoretically and experimentally in this paper. A kind of nonlinear magnetic coupled piezoelectric energy harvester (NMPEH) is designed. The bidirectional screw is used to adjust the relative location of the tip magnets and external magnets to get different nonlinear magnetic forces. It is well known that the nonlinear magnetic force will influence the broadband energy harvesting performance. In order to describe the nonlinear dynamic behavior of the NMPEH, harmonic balance method is employed and its excitation test are performed at different accelerations over the range of 5-30Hz. It is also found that the analytical solutions match well with experimental output voltage. The nonlinear energy collector under the influence of symmetric magnetic force studied in this paper can not only reduce the resonance frequency of the system, but also increase the vibration amplitude of the cantilever beam, thus increasing the power obtained from the vibration environment.

Wavelength conversion technology is imperative for the future high-speed all-optical network. Nonlinear four-wave mixing (FWM) has been used to demonstrate such functionality in various integrated platforms because of their potential for the realization of a chip-scale, fully integrated wavelength converter. Until now, waveguide-based wavelength conversion on a chip requires a pump power beyond the reach of available on-chip lasers. Although high-quality factor (Q) microresonators can be utilized to enhance the FWM efficiency, their narrow resonance linewidths severely limit the maximal data rate in wavelength conversion. In this work, combining the ultrahigh effective nonlinearity from a high-confinement aluminum gallium arsenide waveguide and field enhancement from a microring resonator with a broad resonance linewidth, we realize all-optical wavelength conversion of a 10-Gbaud data signal by using a pump power, for the first time, at a submilliwatt level. With such a low operation power requirement, a fully integrated high-speed wavelength converter is envisioned for the future all-optical network. The waveguide cross-sectional dimension is engineered in a submicron scale to enhance the light confinement, which pushes the device effective nonlinearity to 720 W−1 m−1 while maintaining a broad operation bandwidth covering the telecom S-, C-, and L-bands. Moreover, we demonstrate that a single microring resonator is capable of handling a high-speed data signal at a baud rate up to 40 Gbit/s. All the wavelength conversion experiments are validated with bit-error rate measurements.

Large topological charge optical vortex beams carrying orbital angular momentum have potential applications on optical trapping, optical communication with high capacity, quantum information processing. However, the beam quality is degraded in vortex beams generated with spiral phase plates or resonator mirrors with defect spots and optical conversion efficiency in solid-state lasers is sacrificed by controlling the loss of resonator. It is a big challenge for generating high beam quality, high-order cylindrical vector beams with large topological charge in compact solid-state lasers. Here, high-order cylindrical vector beams [Laguerre-Gaussian (LG) modes with zero degree and order of l, LG0,l] with tunable topological charges up to 14 have been generated in an annular beam pumped Yb:YAG microchip laser by manipulating the pump power-dependent population inversion distribution. Efficient performance with optical efficiency of 17.5% has been achieved. The output power is 1.36 W for a vector-vortex laser with 14 topological charges. The pump power dependent wavelength tunable and dual-wavelength laser oscillation in vector-vortex beams has been observed by controlling the reabsorption loss at 1030 nm. Wavelength tunable, dual-wavelength (1030 and 1050 nm) laser oscillation has been achieved for vector-vortex beams with topological charges of 8, 9, and 10. The laser beam quality factor M2 close to the theoretical value (l + 1) has been achieved for LG0,l vector-vortex beams with tunable topological charges up to 14. This work provides a new effective method for generating large topological charge high-order cylindrical vector beams in solid-state microchip lasers with high efficiency and high beam quality.
Investigation on “cold” and “hot” characteristics of different configurations of corrugated coaxial slow wave structures

Published: October 2019

Various configurations of corrugated coaxial Slow-Wave Structures (SWSs) are utilized in O-type Cherenkov oscillators to achieve different goals. This is the reason why a strategy targeting the proper selection of corrugated coaxial SWSs configurations deserves to be further studied. In this paper, high frequency characteristics of different configurations of corrugated coaxial SWSs are calculated and analyzed. The analysis suggests that the coaxial SWSs with corrugations on inner conductor only are characterized by higher coupling impedance and higher growth rate of microwave oscillations, while the coaxial SWSs with corrugations on the outer conductor only are characterized by higher power capacity. Due to the low power capacity, coupling impedance and growth rate, the coaxial SWSs with corrugations on both inner and outer conductors are not suitable for O-type Cherenkov oscillators desired to operate in the quasi-TEM mode. However, if these devices are desired to operate in the TM01 quasi-π mode, the SWSs with both inner and outer conductor corrugations may be a better choice to make it happen.

Structural Systematics of Lanthanide(III) Picrate Solvates: Adducts of the Carboxamide Ligands Dimethylacetamide and N-Methylpyrrolidinone

Published: October 2019

The carboxamide-O donor ligands dimethylacetamide (dma) and N-methylpyrrolidinone (nmp) form complexes of lanthanide picrates, Ln(pic)3, of stoichiometry Ln(pic)3(carboxamide)3 in a remarkable variety of phases. Complexes [Ln(pic)3(dma)3], Ln=La, Ce, Nd, Sm, Gd, Yb, Lu, and Y, adopt the 9-coordinate molecular form of tricapped trigonal-prismatic coordination geometry seen to predominate, as two stereoisomers, in related species involving dimethylsulfoxide (dmso), trimethylphosphate (tmp), and hexamethylphosphoramide (hmpa) but as four different phases (depending on Ln), none of which is the same as for the previously known La complex. For Ln=Pr, 9-coordinate species of composition [Pr(pic)3(dma)2(alcohol)] (alcohol=ethanol and propan-2-ol) have been characterised and a low quality determination indicates that a similar species (with propan-2-ol) is formed by Y. For nmp, the composition [Ln(pic)3(nmp)3] is maintained across the series for Ln=La, Ce, Pr, Nd, Gd, Er, Tm, Yb, and Lu but 9-coordination is not for Ln=Er, Tm, Yb, and Lu. A decreased coordination there is a result of one or two picrate ligands acting as phenoxide-O donors only, a marked contrast with the analogous Ln(pic)3 complexes with dmso, tmp, hmpa, and dma, where picrate chelation is universal, but with some parallel to related ScIII complexes. Several polymorph pairs can be identified among the nmp complexes.

Most of the world’s tropical coastal and shelf areas are heavily affected by anthropogenic activities, but the north-west shelf of Australia is considered a ‘very low-impact’ area. The role of herbivory on coral reefs is recognised, but most of that research comes from reefs with considerable land-based impacts. In this study we sampled the teleost community and evaluated herbivory on the reef platform at Browse Island, a small isolated island 200km off north-western Australia, using several approaches: (1) tethering of macroalgae; (2) herbivore exclosures; and (3) video footage. In total, 99 teleost species from 26 families were identified. Turf algal consumption was evident and 18 teleost turf consumers were identified. In contrast, no evidence was found of herbivory on large macroalgae, and browsers, the only group able to consume macroalgae, were represented by just four species all belonging to the genus Naso. The lack of diversity among these specialist herbivores may be a consequence of the small surface area of the reef and the distance to other emergent reefs. Based on a model of top-down control of macroalgae, the reef is potentially vulnerable to disturbance. Small isolated reefs can have low resilience despite having low impacts from land.

Published: October 2019

The K to 12 program has been implemented in the Philippines by the Department of Education which implicated an additional two years in the students’ basic education. These ancillary years allow senior high school students to take courses under the core curriculum and the track of choice. Each student must select one track to pursue that can equip him/her with skills to prepare for the future. Prediction of choice of career track in senior high school is advantageous for educational institutions since it gives insights that can help them develop vital programs beneficial for students’ learning in school. In this study, we applied artificial neural network (ANN) to predict the career strand based on the students’ grades in five major subjects. Different ANN models have been considered and compared. In training and testing the models, a sample of 293 student data information was used. The highest accuracy recorded among all the models was 74.1 %.
