Abstract
The present study investigated the effect of optimizing the total dietary arginine (Arg)-to-lysine (Lys) ratios on the metabolism of lactating sows and piglet performance by supplementation with l- Arg during lactation. A total of 200 multiparous sows (three to six parities, Yorkshire × Landrace) were selected and randomly and equally assigned to five groups in lactation, and finally, 36, 34, 35, 36, and 33 dams completed the study in the dietary treatments, respectively, where the diets consisted of five step-up Arg-to-Lys ratios (0.9, 1.0, 1.1, 1.2, and 1.3) by the addition of 0%, 0.10%, 0.20%, 0.30%, and 0.40% Arg. The diets contained 3.37 to 3.38 Mcal of digestible energy/kg energy, 17.73% to 17.75% crude protein, and 0.98% to 1.01% Lys and were fed ad libitum during lactation. The performance of sows and suckling piglets was measured, and plasma and milk samples were collected for analysis. The feed intake of sows as well as litter weight gain during lactation increased linearly (P ≤ 0.05), while maternal backfat and milk composition were not affected (P &gt; 0.05) as the dietary Arg-to-Lys ratios increased. Analyzed plasma biochemical indices, including concentrations of free Arg, Orn, and Glu, and prolactin, insulin, and follicle-stimulating hormone, responded linearly (P ≤ 0.05) to increases in dietary Arg-to-Lys ratios. The dietary Arg-to-Lys ratios of 1.01 and 1.02 were optimal for maternal feed intake and litter weight gain, based on broken-line models. Collectively, the results of this study indicate that increasing total dietary Arg-to-Lys ratios in lactation was beneficial for the performance of lactating sows and suckling piglets, and dietary Arg-to-Lys ratios of 1.01 and 1.02 were optimal, from regression analyses, for the practical feeding of lactating sows.

Abstract
Marjolin’s ulcer (MU) is a rare, aggressive entity with frequent delay in diagnosis for a variety of regions. Although well described and classically taught in medical school, aspects of its treatment remain ill-defined and controversial. A systematic review was performed according to PRISMA guidelines to identify studies discussing patients who underwent surgical treatment of MU. A total of 31 papers, reporting on 1016 patients, were included. Burns were the most common etiology of malignant degeneration (68%), followed by trauma. The lower extremity was most affected (51%) and Squamous Cell Carcinoma (SCC) was found in 94% of cases, with the majority being well differentiated. Basal cell carcinoma and melenoma composed a minority of cases. Melanoma occurred more frequently in previously skin grafted wounds and had a higher rate of metastases than SCC. Most patients did not have associated regional or distant metastases present at diagnosis. Wide local excision (71%) was performed in most cases, unless amputation was indicated for severe disease or bone involvement. Lymphadenectomy and sentinel lymph node biopsy were variably reported, with conflicting evidence on the efficacy. Lymphadenectomy was most commonly indicated for known lymph node involvement. In cases of metastatic disease chemotherapy and radiation were used in conjunction with surgical treatment. Despite numerous articles on this topic, controversy remains in the management of MU. Early diagnosis of suspicious chronic wounds and prompt surgical intervention remains imperative to its treatment.

Published: August 2020

Abstract
A meridic diet overlay bioassay using empty, positively charged zein nanoparticles ((+)ZNP) was performed on soybean looper (Chrysodeixis includens (Walker)), tobacco budworm (Heliothis virescens (F.)), and velvetbean caterpillar (Anticarsia gemmatalis Hübner) (Lepidoptera: Noctuidae). Assessment of effects on mortality and development weights 7 d after ingestion of (+)ZNP were evaluated on larvae of each species. Treatments involved different concentrations, with H. virescens and A. gemmatalis offered 0 and 3,800 ppm (+)ZNP, whereas C. includens colonies were offered 0, 630, 1,260, and 2,520 ppm (+)ZNP. Mortality of A. gemmatalis and C. includens increased after ingestion of the highest (+)ZNP concentrations, while H. virescens neonate mortality was unaffected. Neonate and third-instar weights of A. gemmatalis and C. includens, and neonate H. virescens, decreased with high (+)ZNP concentrations. Following mortality results from A. gemmatalis neonates, a concentration response test was performed using a range of (+)ZNP concentrations. The LC50 for A. gemmatalis was 1,478 ppm. The potential of (+)ZNP as a pest management tactic is discussed.

Abstract
The nutritional status of host plants can have direct impacts on herbivore physiology and insect–plant interactions. We investigated the effect of micronutrients, including manganese, iron, zinc, and copper, on cucumber plant physiology, and on the biology and physiology of a strain of Aphis gossypii Glover selected over 12 generations to be resistant to pirimicarb. The micronutrient treatment increased the activity of superoxide dismutase, ascorbate peroxidase, guaiacol peroxidase, polyphenol oxidase, and phenylalanine ammonia-lyase in cucumber plants, and also increased levels of total phenolics, hydrogen peroxide, salicylic acid, and total chlorophyl, whereas malondialdehyde levels were unaffected. Pirimicarb-resistant cotton aphids that fed on micronutritient-amended cucumber plants expressed significantly decreased levels of acetylcholinesterase and detoxifying enzymes, specifically glutathione S-transferase, and carboxylesterase. Analysis of energy reserves in resistant A. gossypii fed on micronutritient-amended plants revealed decreases in the lipid and protein contents of aphids, whereas glycogen and carbohydrate contents showed no response. Resistant cotton aphids fed on micronutritient-amended plants showed significantly reduced fecundity, longevity, and reproductive periods, and a 1.7-fold reduction in pirimicarb LC50 compared with those fed on control plants. We conclude that micronutrient amendment negatively impacts the biological performance of insecticide-resistant cotton aphids, and diminishes their resistance to pirimicarb. Both direct effects on plant health, such as enhanced inducible defenses, and indirect effects on aphid fitness, such as reduced biological performance and detoxification abilities, were implicated. Therefore, optimization of micronutrient amendments could be a useful complement to other tactics for managing insecticide-resistant A. gossypii on cucumbers, and warrants exploration in other contexts.
Effects of Antibiotics on the Dynamic Balance of Bacteria and Fungi in the Gut of the German Cockroach

Published: August 2020

AbstractThe German cockroach, Blattella germanica (L.) (Blattaria: Blattidae) harbored diverse microorganisms in the digestive tract, including bacteria, fungi, viruses, archaea, and protozoa. This diverse community maintains a relatively stable balance. Some bacteria have been confirmed to play crucial roles in the insect’s physiology, biochemistry, and behavior. Antibiotics can effectively eliminate bacteria and disrupt the balance of gut microbiota, but the time-course of this process, the structure of the new microbial community, and the dynamics of re-assemblage of a bacterial community after antibiotic treatment have not been investigated. In the present study, antibiotic (levofloxacin and gentamicin) ingestion reduced bacterial diversity and abundance in the cockroach gut. Within 14 d of discontinuing antibiotic treatment, the number of culturable gut bacteria returned to its original level. However, the composition of the new bacterial community with greater abundance of antibiotic-resistant Enterococcus and Dysgonomonas was significantly different from the original community. Network analysis showed that antibiotic treatment made the interaction between bacteria and fungi closer and stronger in the cockroach gut during the recovery of gut microorganisms. The study on the composition change, recovery rules, and interaction dynamics between gut bacteria and fungi after antibiotic treatment are helpful to explore gut microbes’ colonization and interaction with insects, which contributes to the selection of stable core gut bacteria as biological carriers of paratransgenesis for controlling Blattella germanica.
Predictive Power in Behavioral Welfare Economics
Authors: Bouacida Elias , Martin Daniel 
Published: August 2020

AbstractWhen choices are inconsistent due to behavioral biases, there is a theoretical debate about whether the structure of a model is necessary for providing precise welfare guidance based on those choices. To address this question empirically, we use standard data sets from the lab and field to evaluate the predictive power of two “model-free” approaches to behavioral welfare analysis. We find they typically have high predictive power, which means there is little ambiguity about what should be selected from each choice set. We also identify properties of revealed preferences that help to explain the predictive power of these approaches.
Seismic shot-encoding schemes for waveform inversion

Published: August 2020

AbstractA shot-encoding technique can be used in seismic waveform inversion to significantly reduce the computational cost by reducing the number of seismic simulations in the inversion procedure. Here we developed two alternative shot-encoding schemes to perform simultaneous-sources waveform inversion. The first scheme (I) encodes shot gathers with random-phase rotations applied to seismic traces. The second scheme (II) encodes shot gathers with random static time shifts. The well-known polarity encoding scheme (III) is just a special case of the random-phase rotation scheme. The second scheme is a variation of the conventional static shift encoding (IV), but the static time shifts in the second scheme are limited to one period of the dominant frequency. All encoded shot gathers are added up into a single super-shot gather for seismic waveform inversion. We perform the time-domain waveform inversion, using these shot-encoding schemes in conjunction with a restarted L-BFGS algorithm in the iterative inversion. The effectiveness and efficiency analyses demonstrate that the two shot-encoding schemes (I and II) proposed in this paper may improve the convergence of the iterative inversion, reduce the crosstalk effect among shots and consequently produce a subsurface velocity model with a high resolution.
The Adventure of the Stradivarius: Violins in the Work of Arthur Conan Doyle and William Crawford Honeyman
Authors: Durkin Rachael 
Published: August 2020

Abstract
The violin, despite its fleeting appearances in the stories of Sherlock Holmes, has become prominently associated with the character of Sherlock in modern TV and film adaptions. While the violin is never investigated by Holmes in the stories, it is represented in more depth in a precursory detective story by William Crawford Honeyman: a Scottish author-musician, whose work appears to have influenced Arthur Conan Doyle’s tales of Sherlock Holmes. Honeyman’s short story ‘The Romance of a Real Cremona’ (1884) follows detective James McGovan as he traces and returns a stolen Stradivari violin and unravels its complex provenance. The importance of the violin’s inclusion in fictional works has been little discussed in scholarship. Here, the texts of Doyle and Honeyman serve as a lens through which to analyse the meaning of the violin during the Victorian era. By analysing the violin from an organological perspective, this article examines the violin’s prominence in nineteenth-century British domestic music-making, both as a fiscally and culturally valuable object. The final section of the article explores the meaning attached to, and created by, the violin in the stories of Doyle and Honeyman.

Triaged Treatment-Based Conventional Weapon Combat Wound Classification Code Design and Injury Spectrum Statistical Analysis
Authors: Peng Bo , Liu Shuo , Xu Lei , He Zhen 
Published: August 2020

Abstract

Introduction
We create an expandable combat wound classification coding system and a stratified standardized combat wound injury spectrum to support triage according to the treatment echelon and to provide the basis for the rapid and efficient classification of combat casualties. The coding system simultaneously assists in identifying injuries with a high incidence of fatality that require emergency treatment, and provides a framework for the triage of combat wounds in mass casualty situations.

Materials and Methods
The three-tiered treatment echelon consisting of battlefield on-site first aid, emergency treatment, and early treatment was used to design an expanded combat wound classification coding system according to the differential needs of combat wound treatment. The Herfindahl−Hirschman Index (HHI) index was used as the key indicator for injury spectrum ranking and was applied to select the key anatomical structures that require the highest priority treatment in the three treatment echelons. The combat wound classification codes were based on the results of consultations with selected experts and results from the HHI index calculations. The use of the classification codes at the battlefield on-site first aid stage and emergency treatment stage was evaluated in exercises to test and compare the effectiveness of the classification codes against current classification systems.

Results
We obtained exhaustive combinations from the vast number of combat wound factors in combat wound classification codes, constructed injury spectrum frameworks within the different treatment echelons, and identified injuries with a high-incidence of fatality in each of the treatment echelons. Compared with traditional methods, the time spent on coding was reduced and classification accuracy was improved when using the new classification codes, which led to improved efficiency of classification and a reduced workload for hospital staff.

Conclusions
The combat wound classification codes that were established through the HHI index and expert consultations achieved good results in terms of having higher classification speed and accuracy than traditional methods. This means they could be used to identify injuries with a high-incidence of fatality and provide guidance to improve the efficiency of treatment among all treatment echelons in the army.
Descriptive and Injunctive Norms Related to E-Cigarettes

Published: August 2020

AbstractIntroductionE-cigarette use has rapidly increased in prevalence in the United States, and rates of use are even higher among military personnel compared to the general population. Descriptive and injunctive norms have previously been shown to impact tobacco use. However, little research has been conducted related to e-cigarette descriptive and injunctive norms, and no research has addressed e-cigarette norms among a military population.Materials and MethodsFrom July, 2018 to February, 2019, 22 focus groups (N = 164) were conducted among airmen, military training leaders, and technical training instructors. The focus groups aimed to gain insight into facilitators and barriers to tobacco use during technical training, where airmen receive training for their specific jobs. Study procedures were approved by the institutional review board of the 59th Medical Wing in San Antonio. Focus group recordings were transcribed, and transcripts coded. Themes related to descriptive and injunctive norms were examined for the current study.ResultsMany interviewees mentioned the prevalence of e-cigarette use, either generally (“…a lot of people vape but that’s kind of the thing nowadays”) or with specific estimates of how many airmen use (“vaping, probably at least 60-70%”). However, injunctive norms were not commonly discussed, with only a couple of interviewees mentioning that e-cigarette use is the “cool” trend or they feel peer pressure.ConclusionsDescriptive norms were more commonly mentioned than injunctive norms, which may indicate that injunctive norms are not as influential for e-cigarette use. Additionally, all estimates related to e-cigarette prevalence were higher than actual rates of use, showing an overestimation of use, which previous literature has shown increases likelihood of e-cigarette use. Future research should specifically ask about injunctive norms as well as determine if descriptive and injunctive norms influence actual e-cigarette use behaviors among military personnel.
A spectroscopic test of the rotational modulation origin of periodic Kepler photometric variability of A-type stars
Authors: Sikora J , Wade G A , Rowe J 
Published: August 2020

ABSTRACT
High-precision space-based photometry obtained by the Kepler and TESS missions has revealed evidence of rotational modulation associated with main-sequence (MS) A- and late B-type stars. Generally, such variability in these objects is attributed to inhomogeneous surface structures (e.g. chemical spots), which are typically linked to strong magnetic fields ($B\gtrsim 100\, {\rm G}$) visible at the surface. It has been reported that ≈44 per cent of all A-type stars observed during the Kepler mission exhibit rotationally modulated light curves. This is surprising considering that ≲10 per cent of all MS A-type stars are known to be strongly magnetic (i.e. they are Ap/Bp stars). We present a spectroscopic monitoring survey of 44 A- and late B-type stars reported to exhibit rotational modulation in their Kepler light curves. The primary goal of this survey is to test the hypothesis that the variability is rotational modulation by comparing each star’s rotational broadening (vsin i) with the equatorial velocities (veq) inferred from the photometric periods. We searched for chemical peculiarities and binary companions in order to provide insight into the origin of the apparent rotational modulation. We find that 14 stars in our sample have vsin i &gt; veq and/or have low-mass companions that may contribute to or be responsible for the observed variability. Our results suggest that more than 10 per cent of all MS A- and late B-type stars may exhibit inhomogeneous surface structures; however, the incidence rate is likely ≲30 per cent.
Short time-scale variability of γ-ray-emitting narrow-line Seyfert 1 galaxies in optical and UV bands
Authors: D’Ammando F 
Published: August 2020

ABSTRACT
We report the first systematic analysis of single exposures of all optical and ultraviolet (UV) observations performed by the UltraViolet and Optical Telescope (UVOT) on board the Neil Gehrels Swift Observatory satellite available up to 2019 April of six γ-ray-emitting narrow-line Seyfert 1 galaxies (NLSy1). Rapid variability has been significantly detected on hours time-scale for 1H 0323+342, SBS 0846+513, PMN J0948+0022, and PKS 2004−447 in 18 observations for a total of 34 events. In particular, we report the first detection of significant variability on short time-scale (3–6 ks) in optical for PKS 2004–447, and UV for 1H 0323+342 and PMN J0948+0022. The shortest variability time-scale observed for 1H 0323+342, SBS 0846+513, PMN J0948+0022, and PKS 2004−447 (assuming a Doppler factor δ = 10) gives a lower limit on the size of emission region between 9.7 × 1014 (for SBS 0846+513) and 1.6 × 1015 cm (for 1H 0323+342), suggesting that the optical and UV emission during these events is produced in compact regions within the jet. These observations provide unambiguous evidence about the relativistically beamed synchrotron emission in these sources, similar to blazars. A remarkable variability has been observed for PMN J0948+0022 on 2009 June 23 with an increase from ∼1.1 to 0.4 mag going from v to w2 filter in ∼1.6 h and a decrease at the initial level in a comparable time. The higher fractional flux change observed for this and other events at lower frequencies suggests that the synchrotron emission is more contaminated by thermal emission from accretion disc at higher frequencies.
Cosmology with relativistically varying physical constants
Authors: Gupta Rajendra P 
Published: August 2020

ABSTRACT
We have shown that the varying physical constant model is consistent with the recently published variational approach wherein Einstein equations are modified to include the variation of the speed of light c, gravitational constant G, and cosmological constant Λ using the Einstein–Hilbert action. The general constraint resulting from satisfying the local conservation laws and contracted Bianchi identities provides the freedom to choose the form of the variation of the constants as well as how their variations are related. When we choose ${\dot{G}}/G = 3\,\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\cdot}$}}{\dot{c}} /c,\,c = {c_0}\,{\rm{exp}}\,[({a^\alpha} - 1)],\,G = {G_0}\,{\rm{exp}}\,[3({a^\alpha} - 1)]$, and ${\rm{\Lambda }} = {{\rm{\Lambda }}_0}\ \exp [ {( {{a^{ - \alpha }} - 1} )} ]$, where a is the scale factor and α = 1.8, we are able to show that the resulting model: (a) fits the supernova 1a observational data marginally better than the Lambda cold dark matter (ΛCDM) model; (b) determines the first peak in the power spectrum of the cosmic microwave background temperature anisotropies at a multipole value of $l = 217.3$; (c) calculates the age of the Universe as 14.1 Gyr; and (d) finds the BAO acoustic scale to be 145.2 Mpc. These numbers are within less than 3 per cent of the values derived using the ΛCDM model. Surprisingly, we find that the dark-energy density is negative in a Universe that has significant negative curvature and whose expansion is accelerating at a faster rate than that predicted by the ΛCDM model.
