Complex BPS solitons with real energies from duality
Authors: Fring Andreas , Taira Takano 
Published: September 2020

Abstract
Following a generic approach that leads to Bogomolny–Prasad–Sommerfield (BPS) soliton solutions by imposing self-duality, we investigate three different types of non-Hermitian field theories. We consider a complex version of a logarithmic potential that possess BPS super-exponential kink and antikink solutions and two different types of complex generalizations of systems of coupled sine-Gordon models with kink and antikink solution of complex versions of arctan type. Despite the fact that all soliton solutions obtained in this manner are complex in the non-Hermitian theories we show that they possess real energies. For the complex extended sine-Gordon model we establish explicitly that the energies are the same as those in an equivalent pair of a non-Hermitian and Hermitian theory obtained from a pseudo-Hermitian approach by means of a Dyson map. We argue that the reality of the energy is due to the topological properties of the complex BPS solutions. These properties result in general from modified versions of antilinear CPT symmetries that relate self-dual and an anti-self-dual theories.
Topological classification of excitations in quadratic bosonic systems
Authors: Zhou Zixian , Wan Liang-Liang , Xu Zhi-Fang 
Published: September 2020

Abstract
We investigate the topological classification of excitations in quadratic bosonic systems with an excitation band gap. Time-reversal, charge-conjugation, and parity symmetries in bosonic systems are introduced to realize a ten-fold symmetry classification. We find a specific decomposition of the quadratic bosonic Hamiltonian and use it to prove that each quadratic bosonic system is homotopic to a direct sum of two single-particle subsystems. The topological classification table is thus derived via inheriting from that of Atland–Zirnbauer classes and unique topological phases of bosons are predicted. Finally, concrete topological models are proposed to demonstrate the peculiarity of bosonic excitations.

Published: September 2020

Abstract
Jepara government took the initiative to construct submerged breakwaters to reduce wave force. Development planning of submerged breakwater need to analyze the reduction of wave spectrum (H and T) around the breakwaters. On this research we applied two variances of structure. Analysis of wave spectrum used 2D hydro-dynamic mathematical model. Data that has been used for input model there are bathymetry data, wind data along 2009-2019, tide data, and coastline data. Wave height and wave period data was obtained by wind data along 2009-2019 which was calculated using DNS method. Model simulation of wave height and period applied in two formation at 5 wind direction (North, Northeast, East, Southeast, and South). Effectiveness is known by the changes of Hmax and T while passing the structure. Based on simulation model, highest wave height found during southeast wind and reduced after passing the breakwaters. Breakwaters with 4 structure (formation 2) has higher reduction percentage. Incoming wave height values decrease after passing submerged breakwater.

Published: September 2020

Abstract
Research on the growth rate of Spirulina sp. carried out in BG-11 medium with UV light intensity of 3000 lux and a temperature of 25 ˚C with the addition of metal ion Cd(II) concentration was carried out. An initial abundance of Spirulina sp. in the medium is 10.103 ind./L with the concentrations of Cd(II) added to the culture medium of 0, 1, 3, and 5 mg/L, respectively. Spirulina sp. growth rate in the control media continued to increase until the exponential phase on the seventh day with growth rate of growth rate of 4.3×103 ind/L/day, while the medium with the addition of Cd(II) with concentrations of 1, 3, and 5 mg/L experienced a decrease in growth rate of 3.9×103 ind/L/day, 3.8×103 ind/L/day, and 0.07×103 ind/L/day, respectively. The concentration of Cd(II) 5 mg/L in the culture medium of Spirulina sp. decreased the growth significantly. So that it can be concluded the potential use of Spirulina sp. as an adsorbent of Cd(II) metal can be effective at concentrations up to 3 mg/L.

Abstract
Western equatorial Pacific is a confluence region of the water mass from the northern hemisphere and the southern hemisphere. One of the interesting phenomena in this region is Halmahera Eddy. The purpose of this research is to investigate the seasonal variability of the Halmahera Eddy on several depths and its relation to the primary productivity using sea surface temperature and chlorophyll-a parameters. In addition, this research also investigates the influence of the surface currents of the Halmahera Eddy to the thermocline layer. The results show that the Halmahera Eddy on the surface is affected by several currents in the waters of the Western Pacific Ocean and the monsoon system that is strengthened in the East Monsoon-Transition II (June-October), while weakened by the end of Transition II-West monsoon (November-February), Current Depth of Halmahera Eddy pattern strengthening, weakening, shifting every seasons and the currents weaker along with increasing depth. The primary productivity is identified by chlorophyll-a (0.1-0.15 mg/m3) and warm pool (28-31ºC) in Halmahera sea. Halmahera Eddy also can suppress the thermocline layer.

AbstractThe aim of research was to determine the effect and the best dosage of estradiol-17β hormone on gonadal development of Java barb (Punctius javanicus). The subjects of this study were 10 months old 48 female (?) Java barb weighing ±200 gram. This research was done experimentally by applying a randomised design (CRD) with 4 treatments and 3 replications. Dosage treatments used were 0, 100, 200, 300 µg/kg body weight. The data observed include body weight, body length, gonado somatic Index (GSI), Gonado Maturation Stage (GMS), hepato somatic index (HSI), total protein plasma (TPP) and water quality. The results showed that the highest body weight was obtained at treatment C 21.42±1.23 g. The highest body length was on treatment C 1.17±0.18 cm. The highest percentage GSI was at treatment C 14.84±0.79%. Meanwhile, the highest GMS were treatment C and D as all samples reached GMS IV on the 30thday. The highest percentage of HSI was at treatment C 2.25±0.36%. Treatment TTP A ranged 4.2-4.6 gr/dL, B 4.4 - 5.4 gr/dL, C 4.4-5.7 gr/dL, and D 4.5-5.8 gr/dL. The water quality of cultivation media was in the proper range at the temperature 26.5-28°C, DO 3-4,1, and pH 7–8. This research concluded that estradiol-17β injection had a significant effect (P<0.05) on body weight gain, GSI, HSI, yet it has not significant effect on body length. The best treatment is treatment C dose of 200 µg/kg body weight.

CdS-coated thin plastic films for visible-light photocatalysis
Authors: McNeill Aaron , Mills Andrew 
Published: September 2020

Abstract
The preparation of a visible light-absorbing, very thin (2.5 μm), flexible CdS nanoparticle coated polystyrene (PS) film, CdS-PS, with a 3D-printed backing is described. Scanning electron microscopy confirms that the CdS-PS film comprise a thin layer of CdS nanoparticles (26 ± 4 nm) on just one side of the PS film, with no nanoparticles on the other side. When irradiated with 420 nm or 365 nm radiation, in air-saturated water, the CdS film is photobleached, and dissolved O2 consumed, due to the photoinduced oxidative corrosion of the CdS by O2. In contrast, under the same aerobic conditions, the CdS-PS film is very stable, when a sacrificial electron donor (SED) is present, such as EDTA or ascorbate/ascorbic acid, with the latter appearing the most effective. In the presence of an SED, the CdS-PS film photocatalyses the reduction of the dyes, methyl orange and crystal violet, and the electron-relay, methyl viologen, by different SEDs, using visible and UV light. In the photocatalysed reduction of methyl viologen by EDTA, colloidal Pt reacts with the highly coloured blue methyl viologen radicals generated to produce H2. Visible light irradiation of the CdS-PS/MV2+/EDTA/colloidal Pt system promotes the reduction of water to H2 by the SED, EDTA, mediated by methyl viologen. A colourless, TiO2-PS film, made using P25 TiO2, is used to effect the same photocatalytic reduction reactions as the CdS-PS film, but only when irradiated with UV (365 nm) radiation. In both cases the films are used repeatedly with no evidence of deterioration in activity or film stability. This is the first example of the preparation and testing of a visible light absorbing photocatalytic, i.e. CdS, thin plastic film, the preparation of which is very simple and inexpensive and may prove invaluable for the production of thin, flexible plastic photocatalytic films for solar research.
The Course of Cognitive Performance during Inpatient Treatment in Patients with Alcohol Use Disorder with No, Mild or Major Neurocognitive Disorders
Authors: Bruijnen C J W H , Walvoort S J W , Dijkstra B A G , de Jong C A J , Kessels R P C 
Published: September 2020

Abstract

Aims
In patients with a history of chronic alcohol abuse, neurocognitive disorders (NCD) are not uncommon. The current study aimed to explore the course of cognitive performance, as measured by the Montreal Cognitive Assessment (MoCA), and everyday cognitive functioning, as measured by the Patient Competency Rating Scale (PCRS), in a large group of patients with alcohol use disorder (AUD) admitted to the Center of Excellence for Korsakov and Alcohol-related Cognitive Impairments.

Methods
A multiple time-series design was used, in which the MoCA was administered at three time points of assessment, and the PCRS was completed by both the patient and a clinician at two time points, all during clinical treatment.

Results
A total of 524 patients were included, 71 of whom were diagnosed with AUD only, 284 with AUD and mild NCD (ARCI) and 169 with AUD, major NCD and fulfilling criteria for Korsakoff’s syndrome (KS).

Conclusions
Cognitive performance improved for all three groups during treatment, sustained abstinence and recovery from AUD. A low memory performance on the MoCA without improvement over time was predictive for KS, while improvement on this domain did not differentiate between AUD and ARCI. Changes in overall cognitive performance and orientation in patients with KS were positively related to changes in everyday cognitive functioning.
Patterns of intraspecific trait variation along an aridity gradient suggest both drought escape and drought tolerance strategies in an invasive herb
Authors: Welles Shana R , Funk Jennifer L 
Published: September 2020

Abstract

Background and Aims
In water-limited landscapes, some plants build structures that enable them to survive with minimal water (drought resistance). Instead of making structures that allow survival through times of water limitation, annual plants may invoke a drought escape strategy where they complete growth and reproduction when water is available. Drought escape and resistance each require a unique combination of traits and therefore plants are likely to have a suite of trait values that are consistent with a single drought response strategy. In environments where conditions are variable, plants may additionally evolve phenotypically plastic trait responses to water availability. Invasive annual species commonly occur in arid and semi-arid environments and many will be subject to reduced water availability associated with climate change. Assessing intraspecific trait variation across environmental gradients is a valuable tool for understanding how invasive plants establish and persist in arid environments.

Methods
In this study, we used a common garden experiment with two levels of water availability to determine how traits related to carbon assimilation, water use, biomass allocation and flowering phenology vary in California wild radish populations across an aridity gradient.

Key Results
We found that populations from arid environments have rapid flowering and increased allocation to root biomass, traits associated with both drought escape and tolerance. Early flowering was associated with higher leaf nitrogen concentration and lower leaf mass per area, traits associated with high resource acquisition. While trait values varied across low- and high-water treatments, these shifts were consistent across populations, indicating no differential plasticity across the aridity gradient.

Conclusions
While previous studies have suggested that drought escape and drought resistance are mutually exclusive drought response strategies, our findings suggest that invasive annuals may employ both strategies to succeed in novel semi-arid environments. As many regions are expected to become more arid in the future, investigations of intraspecific trait variation within low water environments help to inform our understanding of potential evolutionary responses to increased aridity in invasive species.
Plumage patterns: Ecological functions, evolutionary origins, and advances in quantification
Authors: Mason Nicholas A , Bowie Rauri C K 
Published: September 2020

AbstractBirds exhibit remarkable variation in plumage patterns, both within individual feathers and among plumage patches. Differences in the size, shape, and location of pigments and structural colors comprise important visual signals involved in mate choice, social signaling, camouflage, and many other functions. While ornithologists have studied plumage patterns for centuries, recent technological advances in digital image acquisition and processing have transformed pattern quantification methods, enabling comprehensive, detailed datasets of pattern phenotypes that were heretofore inaccessible. In this review, we synthesize recent and classic studies of plumage patterns at different evolutionary and organismal scales and discuss the various roles that plumage patterns play in avian biology. We dissect the role of plumage patches as signals within and among species. We also consider the evolutionary history of plumage patterns, including phylogenetic comparative studies and evolutionary developmental research of the genetic architecture underlying plumage patterns. We also survey an expanding toolbox of new methods that characterize and quantify the size, shape, and distribution of plumage patches. Finally, we provide a worked example to illustrate a potential workflow with dorsal plumage patterns among subspecies of the Horned Lark (Eremophila alpestris) in western North America. Studies of plumage patterning and coloration have played a prominent role in ornithology thus far, and recent methodological and conceptual advances have opened new avenues of research on the ecological functions and evolutionary origins of plumage patterns in birds.

Published: September 2020

AbstractDrug similarities play an important role in modern biology and medicine, as they help scientists gain deep insights into drugs’ therapeutic mechanisms and conduct wet labs that may significantly improve the efficiency of drug research and development. Nowadays, a number of drug-related databases have been constructed, with which many methods have been developed for computing similarities between drugs for studying associations between drugs, human diseases, proteins (drug targets) and more. In this review, firstly, we briefly introduce the publicly available drug-related databases. Secondly, based on different drug features, interaction relationships and multimodal data, we summarize similarity calculation methods in details. Then, we discuss the applications of drug similarities in various biological and medical areas. Finally, we evaluate drug similarity calculation methods with common evaluation metrics to illustrate the important roles of drug similarity measures on different applications.
