ABSTRACT
Basal progenitor cells are crucial for the establishment and maintenance of the tracheal epithelium. However, it remains unclear how these progenitor cells are specified during foregut development. Here, we found that ablation of the Wnt chaperone protein Gpr177 (also known as Wntless) in mouse tracheal epithelium causes a significant reduction in the number of basal progenitor cells accompanied by cartilage loss in Shh-Cre;Gpr177loxp/loxp mutants. Consistent with the association between cartilage and basal cell development, Nkx2.1+p63+ basal cells are co-present with cartilage nodules in Shh-Cre;Ctnnb1DM/loxp mutants, which maintain partial cell-cell adhesion but not the transcription regulation function of β-catenin. More importantly, deletion of Ctnnb1 in the mesenchyme leads to the loss of basal cells and cartilage, concomitant with reduced transcript levels of Fgf10 in Dermo1-Cre;Ctnnb1loxp/loxp mutants. Furthermore, deletion of Fgf receptor 2 (Fgfr2) in the epithelium also leads to significantly reduced numbers of basal cells, supporting the importance of Wnt/Fgf crosstalk in early tracheal development.
The Effect of the Say-on-Pay Vote in the United States
Authors: Iliev Peter , Vitanova Svetla 
Published: January 2019

The Dodd–Frank Act mandated advisory shareholder votes on executive compensation. To isolate the effect of holding a Say-on-Pay vote we use an exemption provided to a group of firms based on their public float. We find that the regulation increased the level of CEO pay and the fraction of performance-linked pay in the companies that had to comply with the new rule. This increase was larger for CEOs with higher ownership and longer tenure. Moreover, the market reacted negatively to the exemption from the Say-on-Pay rule suggesting general support for holding the Say-on-Pay votes. These effects are not present in placebo specifications in previous years or in different groups. This paper was accepted by Lauren Cohen, finance.

Effect of Various Yeasts Antagonists on Anthracnose Disease and the Shelf Life of MangoPostharvest decay on mango may occur due to physiological damage and/or postharvest disease especially anthracnose. This postharvest decay may decrease the quality of mango fruit. The use of antagonists yeast as biocontrol agent is an alternative control measure for postharvest diseases of fruits. This study aimed to screen yeast species as biological control agents and in the same time delaying the maturity of fruits to extend its shelf life. Six isolates of yeasts were evaluated, namely Cryptococcus albidus, Cryptococcus terreus, Aureobasidium pullulans, Rhodotorula minuta, Candida tropicalis, Pseoudozyma hubeiensis); fungicides treatment using azoksistrobin was applied for comparative treatment. The study was conducted at two temperature conditions, namely room temperature and 15 ° C. It was evidenced that C. albidus, A. pullulans, and C. tropicalis were effective to control anthracnose disease on mango under both temperatures. Furthermore, C. tropicalis and A. pullulans were able to extend manggo shelf life for 21 days at room temperature and for 54 days at 15 °C, respectively.

Published: January 2019

Abstract
Residence-time distribution (RTD) experiments were performed to analyze an industrial scale three-tube series continuous pulping digester’s hydrodynamic performance. An impulse of radiotracer 82Br (γ energy source) was introduced at the inlet of the first tube. The radiotracer concentration in the liquid phase was traced at the outlet of each tube. The input behavior of the radiotracer converted to a non-ideal pulse tracer input for the second and third tubes of the digester. Numerical convolution is adopted to deal with the non-ideal pulse input of the radiotracer. A modeling procedure for determining the RTD from the outlet tracer concentration data is proposed. A plug flow component followed by axial dispersion model is considered, and is adjusted after its convolution with the inlet tracer concentration data to obtain the RTD of the individual tubes. The obtained RTD data are analyzed to explain the flow behavior, degree of dispersion, and flow abnormalities existing in the digester. The mean residence-time (MRT), and dispersion number are estimated for the model components for the three tubes. The vessel dispersion number is found to decrease from tube 1 to tube 3. Overall, the conversion of the highly dispersed flow regime into the plug-flow regime is observed in the whole digester.
Sixth-Kind Chebyshev Spectral Approach for Solving Fractional Differential Equations
Authors: Abd-Elhameed W. M. , Youssri Y. H. 
Published: January 2019

AbstractThe basic aim of this paper is to develop new numerical algorithms for solving some linear and nonlinear fractional-order differential equations. We have developed a new type of Chebyshev polynomials, namely, Chebyshev polynomials of sixth kind. This type of polynomials is a special class of symmetric orthogonal polynomials, involving four parameters that were constructed with the aid of the extended Sturm–Liouville theorem for symmetric functions. The proposed algorithms are basically built on reducing the fractional-order differential equations with their initial/boundary conditions to systems of algebraic equations which can be efficiently solved. The new proposed algorithms are supported by a detailed study of the convergence and error analysis of the sixth-kind Chebyshev expansion. New connection formulae between Chebyshev polynomials of the second and sixth kinds were established for this study. Some examples were displayed to illustrate the efficiency of the proposed algorithms compared to other methods in literature. The proposed algorithms have provided accurate results, even using few terms of the proposed expansion.
On Kant’s Derivation of the Categories
Authors: Borboa Santiago de Jesus Sanchez 
Published: January 2019

Abstract
In this paper, I put forth a novel interpretation of how the third categories under each heading in the table of categories (totality, limitation, community, and necessity) are derived. Drawing on a passage from the first Critique and a letter to Schultz, I argue that in order to derive these categories, a special act of the understanding is required. I propose that we interpret this special act as consisting of an application of the third logical function under the corresponding heading that unites the combination of the first and second categories (under that same heading) so as to produce the third.
Self-organization of surfaces on the nanoscale by topography-mediated selection of quasi-cylindrical and plasmonic waves
Authors: Rudenko Anton , Mauclair Cyril , Garrelie Florence , Stoian Razvan , Colombier Jean-Philippe 
Published: January 2019

Abstract
Using coupled electromagnetic and hydrodynamic calculations, we elucidate theoretically the topographic transition from a random metallic surface to a periodic sub-wavelength grating by ultrashort laser ablation. The origin of this transition lies in the successive selection of hybrid surface waves scattered by random nanoholes. Contrary to the common belief that surface plasmon polaritons play the dominant role in the process and define the grating periodicity, we show that both quasi-cylindrical and surface plasmon waves are involved, whereas the diversity in the resulting spacings λ/2–λ (λ is the laser wavelength) is the manifestation of a broad frequency overlap of these waves, controlled by their relative phase shifts with respect to the plasmonic counterparts. The topography evolution imposes the dominant contribution to the surface sub-wavelength pattern by selecting the appropriate wave character from plasmonic modes to evanescent cylindrical waves. With the radiation dose, the grating periodicity exhibits a pronounced blue shift due to reinforced dipole–dipole coupling between the nanoholes and surface curvatures in the laser-processed area. This allows the creation of regular patterns with tunable periodicity.

Using chemical synthesis to optimise antimicrobial peptides in the fight against antimicrobial resistance
Authors: Li Freda F. , Brimble Margaret A. 
Published: January 2019

Abstract
The emergence of multidrug-resistant bacteria has necessitated the urgent need for novel antibacterial agents. Antimicrobial peptides (AMPs), the host-defence molecules of most living organisms, have shown great promise as potential antibiotic candidates due to their multiple mechanisms of action which result in very low or negligible induction of resistance. However, the development of AMPs for clinical use has been limited by their potential toxicity to animal cells, low metabolic stability and high manufacturing cost. Extensive efforts have therefore been directed towards the development of enhanced variants of natural AMPs to overcome these aforementioned limitations. In this review, we present our efforts focused on development of efficient strategies to prepare several recently discovered AMPs including antitubercular peptides. The design and synthesis of more potent and stable AMP analogues with synthetic modifications made to the natural peptides containing glycosylated residues or disulfide bridges are described.
Gumbula and Knowledge Generation in Collections in the USA: Where is Joe’s Right Shoe?
Authors: Hamby Louise 
Published: January 2019

AbstractThis paper explores the methodology and aspirations of an Indigenous researcher and his work with others working within the Galleries, Libraries, Archives, Museums and Records (GLAMR) sector. In 2010, Joseph Neparrŋa Gumbula visited four cultural institutions in the USA to examine their Milingimbi collections and, in particular, those from his own Gupapuyŋu clan. Gumbula’s methodology brought new discoveries, and questions the approach of established research in museums.
Dialogues with the Archives: Arrarrkpi Responses to Recordings as Part of the Living Song Tradition of Manyardi
Authors: Brown Reuben , Manmurulu David , Manmurulu Jenny , O’Keeffe Isabel 
Published: January 2019

AbstractThis article explores the role of legacy recordings of song for a family of Arrarrkpi (Mawng-speaking people), who are contemporary singers and dancers of manyardi, a public ceremonial performance of western Arnhem Land, in their collaborative work with a team of Balanda (Euro-diasporic) researchers. Drawing inspiration from the dialogical approach of the Yolŋu ceremonial leader and scholar Joe Gumbula, the article reflects on various dialogues that inform the research, practice and archival recording of manyardi. We demonstrate how legacy recordings reinvigorate contemporary performance practice in collective settings, rather than serving as canonical or ideal versions of song sets to be replicated by an individual singer. We suggest that maintaining the linking and organisation of enriched song metadata from this community to the archival collection will enable future song inheritors to maintain dialogues with archives that hold recordings of manyardi.
Matjabala Mali’ Buku-ruŋanmaram: New Pathways for Indigenous Cultural Survival through Yolŋu Explorations of the University of Sydney Archives
Authors: Gumbula Joseph Neparrŋa 
Published: January 2019

AbstractThis article was adapted by Aaron Corn from a lecture presented by Joe Gumbula at the Koori Centre at the University of Sydney on 5 April 2007. The day before, Joe had been admitted to the degree of Doctor of Music honoris causa at the University, and had only recently started work at the Koori Centre on his first Australian Research Council (ARC) project as an ARC Indigenous Research Fellow. Called “Elder Assessments of Early Material Culture Collections from Arnhem Land and Contemporary Access Needs to them among their Source Communities” (DI0775822) and including Aaron Corn as a nominal Mentor, this was the first ARC project to be led by a Yolŋu Chief Investigator. It enabled Joe to undertake detailed research into the Yolŋu heritage collections held in the University of Sydney’s Archives and Macleay Museum. Eighteen members of Joe’s family from Miliŋinbi (Milingimbi) and Galiwin’ku, who were visiting Sydney to attend his graduation ceremony, were present at this lecture. Joe’s assured and impassioned delivery on this occasion aptly demonstrates his exemplary knowledge of Yolŋu heritage, his mastery in applying Yolŋu law to its interpretation, and his ability to engage others in the process and significance of collections research. All University of Sydney materials that Joe presented in the lecture were later published in his 2011 book, Matjabala Mali’ Buku-ruŋanmaram: Images from Miliŋinbi (Milingimbi) and Surrounds, 1926–1948, and, in this article, are cross-referenced to this source, which remains available for purchase from Sydney University Press.
Feasibility Study of Textureless Object Detection and Pose Estimation Based on a Model with 3D Edgels and Surfaces
Authors: Yamazaki Kimitoshi , Sogen Kiyohiro , Yamamoto Takashi , Inaba Masayuki 
Published: January 2019

Abstract
This paper describes a method for the detection
of textureless objects. Our target objects include furniture
and home appliances, which have no rich textural
features or characteristic shapes. Focusing on the ease of
application, we define a model that represents objects in
terms of three-dimensional edgels and surfaces. Object detection
is performed by superimposing input data on the
model. A two-stage algorithm is applied to bring out object
poses. Surfaces are used to extract candidates fromthe
input data, and edgels are then used to identify the pose
of a target object using two-dimensional template matching.
Experiments using four real furniture and home appliances
were performed to show the feasibility of the proposed
method.We suggest the possible applicability in occlusion
and clutter conditions.

Abstract
Tiernan, C, Lyons, M, Comyns, T, Nevill, AM, and Warrington, G. Salivary IgA as a predictor of upper respiratory tract infections and relationship to training load in elite rugby union players. J Strength Cond Res 34(3): 782–790, 2020—Upper Respiratory Tract Infections (URTI) are among the most common illnesses reported in athletes. An URTI can result in missed training days, which in turn may lead to performance decrements. The purpose of this study was to investigate the use of salivary immunoglobulin A (sIgA) as a predictor of URTI, while also exploring the relationship to weekly training load in elite rugby union players. Nineteen male elite rugby union players provided morning saliva swabs, biweekly (Monday and Friday), over a 10-week training period. Participants completed an illness log documenting symptoms of URTI. Session Rate of Perceived Exertion (sRPE) was collected to determine training load (sRPE × session duration). Weekly training load was also calculated. Logistic regression was used to analyze the relationship between incidences of URTI with sIgA and training load. Multilevel regression was conducted to compare associations between sIgA and training load. The results found that the likelihood of suffering from an URTI increased when sIgA significantly decreased (p = 0.046). Where sIgA decreased by 65% or more, a player was at a greater risk of contracting an URTI within the following 2 weeks. No association was found between sIgA and training load. In conclusion, sIgA may be a useful predictor for determining the likelihood of players contracting an URTI. This will allow the coach to make informed decisions on training status, helping reduce the risk of players missing training, which may have performance decrements. Coaches will benefit from the fast, easy, and instant results available, to analyze a player's immune function.

Abstract
Gastin, PB, Hunkin, SL, Fahrner, B, and Robertson, S. Deceleration, acceleration, and impacts are strong contributors to muscle damage in professional Australian football. J Strength Cond Res 33(12): 3374–3383, 2019—The purpose of this study was to investigate the relationships between serum creatine kinase [CK], an indirect marker of muscle damage, and specific indices of match load in elite Australian football. Twenty-six professional players were assessed during a competitive Australian Football League (AFL) season. [CK] was collected 24–36 hours before match and 34–40 hours after match during 8 in-season rounds. An athlete-tracking technology was used to quantify match load. Generalized estimating equations and random forest models were constructed to determine the extent to which match-load indices and pre-match [CK] explained post-match [CK]. There was a 129 ± 152% increase in [CK] in response to AFL competition. Generalized estimating equations found that number of impacts >3g (p = 0.004) and game time (p = 0.016) were most strongly associated with post-match [CK]. Random forest, with considerably lower errors (130 vs. 316 U·L−1), found deceleration, acceleration, impacts >3g, and sprint distance to be the strongest predictors. Pre-match [CK] accounted for 11% of post-match [CK], and considerable interindividual and intraindividual variability existed in the data. Creatine kinase, an indicator of muscle damage, was considerably elevated as a result of AFL competition. Parametric and machine-learning analysis techniques found several indices of physical load associated with muscle damage during competition, with impacts >3g and high-intensity running variables as the strongest predictors. [CK] may be used as a global measure of muscle damage in field team sports such as AF, yet with some caution given cost, invasiveness, and inherent variability. Quantifying physical load and the responses to that load can guide athlete management decision-making and is best undertaken within a suite of practical, sport-specific measures, where data are interpreted individually and with an understanding of the limitations.

Nakao, S, Ikezoe, T, Nakamura, M, Umegaki, H, Fujita, K, Umehara, J, Kobayashi, T, Ibuki, S, and Ichihashi, N. Chronic effects of a static stretching program on hamstring strength. J Strength Cond Res 35(7): 1924–1929, 2021—This study investigated the effects of a 4-week static stretching (SS) program on isokinetic and isometric knee flexor peak torque and angle of peak torque. Thirty healthy men (age, 22.7 ± 2.2 years) were randomized to receive either of the following: (a) a 4-week stretch intervention for the hamstrings (SS intervention group; n = 15) or (b) no intervention (control group; n = 15). The maximum pain-free knee angle, passive stiffness, which was determined by a slope of torque-angle curve, isometric and isokinetic (at 60°·s−1 and 180°·s−1) peak torque, and angle of peak torque for knee flexors were measured before and after 4 weeks. After 4 weeks, passive stiffness decreased significantly in the intervention group. There were no significant changes in isometric and isokinetic (neither at 60°·s−1 nor at 180°·s−1) peak torque, or angle of peak torque at 180°·s−1. A significantly increased peak extension angle at 60°·s−1 was observed in the intervention group. These results suggest that SS intervention is effective for decreasing musculotendinous unit stiffness of the hamstrings and that an SS program influences the angle of peak torque, whereas no significant changes occur in peak torque. Because a previous study suggests that angle of peak torque is associated with hamstring strain injuries, the results of this study would be helpful when considering the training program for preventing or treating hamstring strain injuries.

Published: January 2019

Abstract
In this study, polyester, i.e., Poly(ethylene terephthalate) (PET) nonwoven fabric, was coated with white tuff, perlite, and volcanic stone powder at rates of 10, 20, 30 and 40 % so as to increase the thermal insulation properties of PET nonwoven fabric. In order to apply white tuff, perlite, and volcanic stone powder to PET nonwoven fabric, polyurethane-based coating material was used as a cross-linking agent. The porosity and thermal conductivity coefficients of samples were then investigated as regards the type and concentration of stone powder. Furthermore, three-layer feed-forward artificial neural network (3FFNN) was used to estimate and verify the accuracy of the thermal conductivity coefficient of PET nonwovens coated with white tuff, perlite, and volcanic stone powder. The results showed that perlite stone powder provided higher thermal insulation compared to white tuff and volcanic stone powder. Moreover, thermal insulation coefficient of samples increased with the rise in concentration of white tuff, perlite, and volcanic stone powder. Besides, the accuracy of 3FFNN was 99 %. Artificial neural network (ANN)-based results showed that the thermal conductivity coefficients of samples with four different concentrations obtained from white tuff, perlite, and volcanic stone powder were almost the same for experimental and ANN-trained models. According to the results, it was seen that 3FFNN was correctly modeled, and the prediction of the thermal conductivity coefficients was successfully realized.
