description: We study dynamical chiral symmetry breaking for quarks in the fundamental representation of $SU(N_c)$ for $N_f$ number of light quark flavors. We also investigate the phase diagram of quantum chromodynamics at finite temperature $T$ and/or in the presence of a constant external magnetic field $eB$. The unified formalism for this analysis is provided by a symmetry-preserving Schwinger-Dyson equations treatment of a vector$\times$vector contact interaction model which encodes several well-established features of quantum chromodynamics to mimic the latter as closely as possible. Deconfinement and chiral symmetry restoration are triggered above a critical value of $N_f$ at $T=0=eB$. On the other hand, increasing temperature itself screens strong interactions, thus ensuring that a smaller value of $N_f$ is sufficient to restore chiral symmetry at higher temperatures. We also observe the well-known phenomenon of magnetic catalysis for a strong enough magnetic field. However, we note that if the effective coupling strength of the model decreases as a function of magnetic field, it can trigger inverse magnetic catalysis in a certain window of this functional dependence. Our model allows for the simultaneous onset of dynamical chiral symmetry breaking and confinement for each case. Qualitative as well as quantitative predictions of our simple but effective model are in reasonably satisfactory agreement with lattice results and other reliable and refined predictions based upon intricate continuum studies of quantum chromodynamics.

description: The farming of channel catfish (Ictalurus punctatus) is the largest (by volume and value) and most successful (in terms of market impact) aquaculture industry in the United States of America. Farmed channel catfish is the most consumed (in terms of volume per capita) fish fillet in the U.S. market. Within Australia, it has long been suggested by researchers and industry that silver perch (Bidyanus bidyanus) and possibly other endemic teraponid species possess similar biological attributes for aquaculture as channel catfish and may have the potential to generate a similar industry. The current teraponid industry in Australia, however, shows very little resemblance to the catfish industry, either in production style or market philosophy. A well established budget framework from the literature on U.S. channel catfish farming has been adapted for cost and climate conditions of the Burdekin region, Queensland, Australia. Breakeven prices for the hypothetical teraponid farms were found to be up to 50% higher than those published for catfish farms however were much lower than those reported for silver perch production in Australia using current, endemic styles of production. The breakeven prices for the hypothetical teraponid farms were most sensitive (in order of significance) to feed prices, production rates, interest rates, fingerling prices and electricity prices. At equivalent feed costs the costs of production between the hypothetical catfish farms in the Mississippi, U.S. and the hypothetical teraponid farms in the Burdekin, Australia were remarkably similar. The cost of feeds suitable for teraponid production in Australia are currently around double that of catfish feeds in the U.S. Issues currently hindering the development of a large scale teraponid industry in Australia are discussed.

description: Observational evidence indicating that the expansion of the universe is accelerating has surprised cosmologists in recent years. Cosmological models have sought to explain this acceleration by incorporating `dark energy', of which the traditional cosmological constant is just one possible candidate. Several cosmological models involving an evolving equation of state of the dark energy have been proposed, as well as possible energy exchange to other components, such as dark matter. This paper summarises the forms of the most prominent models and discusses their implications for cosmology and astrophysics. Finally, this paper examines the current and future observational constraints on the nature of dark energy.

description: Among 12672 Feynman diagrams contributing to the electron anomalous magnetic moment at the tenth order, 6354 are the diagrams having no lepton loops, i.e., those of quenched type. Because the renormalization structure of these diagrams is very complicated, some automation scheme is inevitable to calculate them. We developed an algorithm to write down FORTRAN programs for numerical evaluation of these diagrams, where the necessary counterterms to subtract out ultraviolet subdivergence are generated according to Zimmermann's forest formula. Thus far we have evaluated crudely integrals of 2232 tenth-order vertex diagrams which require vertex renormalization only. Remaining 4122 diagrams, which have ultraviolet-divergent self-energy subdiagrams and infrared-divergent subdiagrams, are being evaluated by giving small mass lambda to photons to control the infrared problem.

description: This paper uses a modified policy analysis matrix (PAM) approach to assess the efficiency of cotton production in five major producing states in India. The results indicate that cotton is not efficiently produced in the second largest cotton producing state in the country. Without government interventions, it is likely that acreage will move away from cotton to more profitable crops such as sugarcane and groundnut in this state. In addition, it is also concluded that cotton is not the most efficiently produced crop in the other four states; however, there is at least one crop in each state which is less efficiently produced than cotton. These findings suggest that Indian policies directed at maintaining the availability of cheap cotton for the handloom and textile sectors have induced major inefficiencies in the cotton sector.

description: Knowledge of the ground state of a homogeneous quantum many-body system can be used to find the exact ground state of a dual inhomogeneous system with a confining potential. For the complete family of parent Hamiltonians with a ground state of Bijl-Jastrow form in free space, the dual system is shown to include a one-body harmonic potential and two-body long-range interactions. The extension to anharmonic potentials and quantum solids with Nosanov-Jastrow wavefunctions is also presented. We apply this exact mapping to construct eigenstates of trapped systems from free-space solutions with a variety of pair correlation functions and interparticle interactions.

description: John Couch Adams predicted the location of Neptune in the sky, calculated the expectation of the change in the mean motion of the Moon due to the Earth's pull, and determined the origin and the orbit of the Leonids meteor shower which had puzzled astronomers for almost a thousand years. With his achievements Adams can be compared with his good friend George Stokes. Not only were they born in the same year, but were also both senior wranglers, received the Smith's Prizes and Copley medals, lived, thought and researched at Pembroke College, and shared an appreciation of Newton. On the other hand, Adams' prediction of Neptune's location had absolutely no influence on its discovery in Berlin. His lunar theory did not offer a physical explanation for the Moon's motion. The origin of the Leonids was explained by others before him. Adams refused a knighthood and an appointment as Astronomer Royal. He was reluctant and slow to publish, but loved to derive the values of logarithms to 263 decimal places. The maths and calculations at which he so excelled mark one of the high points of celestial mechanics, but are rarely taught nowadays in undergraduate courses. The differences and similarities between Adams and Stokes could not be more striking. This volume attests to the lasting legacy of Stokes' scientific work. What is then Adams' legacy? In this contribution I will outline Adams' life, instances when Stokes' and Adams' lives touched the most, his scientific achievements and a usually overlooked legacy: female higher education and support of a woman astronomer.

description: Entanglement plays a crucial role in the security of quantum key distribution. A secret key can only be obtained by two parties if there exists a corresponding entanglement-based description of the protocol in which entanglement is witnessed, as shown by Curty et al (2004). Here we investigate the role of entanglement for the generalization of quantum key distribution to the multipartite scenario, namely conference key agreement. In particular, we ask whether the strongest form of multipartite entanglement, namely genuine multipartite entanglement, is necessary to establish a conference key. We show that, surprisingly, a non-zero conference key can be obtained even if the parties share biseparable states in each round of the protocol. Moreover we relate conference key agreement with entanglement witnesses and show that a non-zero conference key can be interpreted as a non-linear entanglement witness that detects a class of states which cannot be detected by usual linear entanglement witnesses.

description: Intermediate mass black holes have been alternatively predicted to be quite common in the centers of globular clusters or nearly impossible to form and retain in the centers of globular clusters. As it has been recently shown that radio observations are currently the most sensitive observational technique for detecting such objects, we have obtained new deep radio observations of Omega Cen, and have re-analyzed older observations of M~15 in hope of constraining the masses of possible black holes in their centers. In both cases, upper limits of about 100 $μ$Jy are found at GHz frequencies. We find that if the Bondi-Hoyle accretion rate truly represents the spherical accretion rate onto a black hole, then the masses of the black holes in the centers of these two galaxies are severely constrained - with mass limits of less than about 100 solar masses in both cases. If more realistic assumptions are made based on recent work showing the Bondi rate to be a severe overestimate, then the data for Omega Cen are marginally consistent with a black hole of about 1/1000 the cluster's mass (i.e. about 1000 $M_\odot$). The data for M~15 then are only marginally consistent with previous reports of a $\sim2000$ solar mass black hole, and we note that there is considerable hope for either detecting the black hole or improving this upper limit with current instrumentation. Finally, we discuss the possibility that the radio source near the core of the Ursa Minor dwarf spheroidal galaxy is a $\sim10^4$ $M_\odot$ black hole.

description: Social media has become a crucial open-access platform for individuals to express opinions and share experiences. However, leveraging low-resource language data from Twitter is challenging due to scarce, poor-quality content and the major variations in language use, such as slang and code-switching. Identifying tweets in these languages can be difficult as Twitter primarily supports high-resource languages. We analyze Kenyan code-switched data and evaluate four state-of-the-art (SOTA) transformer-based pretrained models for sentiment and emotion classification, using supervised and semi-supervised methods. We detail the methodology behind data collection and annotation, and the challenges encountered during the data curation phase. Our results show that XLM-R outperforms other models; for sentiment analysis, XLM-R supervised model achieves the highest accuracy (69.2\%) and F1 score (66.1\%), XLM-R semi-supervised (67.2\% accuracy, 64.1\% F1 score). In emotion analysis, DistilBERT supervised leads in accuracy (59.8\%) and F1 score (31\%), mBERT semi-supervised (accuracy (59\% and F1 score 26.5\%). AfriBERTa models show the lowest accuracy and F1 scores. All models tend to predict neutral sentiment, with Afri-BERT showing the highest bias and unique sensitivity to empathy emotion. https://github.com/NEtori21/Ride_hailing

description: Domestic subsidies for cotton and other commodities have been a major topic of interest, especially during the Doha Round of the World Trade Organization trade negotiations. Many developing countries have insisted that domestic subsidies in countries like the United States represent significant trade barriers because they lower world price below their cost of production. India, Brazil, and other developing countries intimate that unless these domestic subsidies are lowered, they are unwilling to provide any more market access concessions in trade negotiations.

description: A classical local cellular automaton can describe an interacting quantum field theory for fermions. We construct a simple classical automaton for a particular version of the Thirring model with imaginary coupling. This interacting fermionic quantum field theory obeys a unitary time evolution and shows all properties of quantum mechanics. Classical cellular automata with probabilistic initial conditions admit a description in the formalism of quantum mechanics. Our model exhibits interesting features as spontaneous symmetry breaking or solitons. The same model can be formulated as a generalized Ising model. This euclidean lattice model can be investigated by standard techniques of statistical physics as Monte Carlo simulations. Our model is an example how quantum mechanics emerges from classical statistics.

description: In this paper, we calculate the drag force of a charged particle in systems with hyperscaling violation using the AdS/CFT correspondence. We obtain energy loss, friction coefficient, diffusion and quasi normal modes of a heavy point particle. Here, we consider two cases. In the first, we assume the heavy point particle moves with constant velocity v. In the second case, we assume the heavy point particle rotates along a circle of radius L with angular velocity ω. Also, we add some electromagnetic field and obtain the energy loss. Finally, we draw some figures for the drag force with respect to the velocity and the temperature. As well, we show how the drag force and energy loss change with the hyperscaling violation parameter θ, dynamical parameter z, mass m and charge Q.

description: In most galaxies like the Milky Way, stars form in clouds of molecular gas. Unlike the CO emission that traces the bulk of molecular gas, the rotational transitions of HCN and CS molecules mainly probe the dense phase of molecular gas, which has a tight and almost linear relation with the far-infrared luminosity and star formation rate. However, it is unclear if dense molecular gas exists at very low metallicity, and if exists, how it is related to star formation. In this work, we report ALMA observations of the CS $J$=5$\rightarrow$4 emission line of DDO~70, a nearby gas-rich dwarf galaxy with $\sim7\%$ solar metallicity. We did not detect CS emission from all regions with strong CO emission. After stacking all CS spectra from CO-bright clumps, we find no more than a marginal detection of CS $J$=5$\rightarrow$4 transition, at a signal-to-noise ratio of $\sim 3.3$. This 3-$σ$ upper limit deviates from the $L^\prime_{\rm CS}$-$L_{\rm IR}$ and $L^\prime_{\rm CS}$-SFR relationships found in local star forming galaxies and dense clumps in the Milky Way, implying weaker CS emission at given IR luminosity and SFR. We discuss the possible mechanisms that suppress CS emission at low metallicity.

description: The Food, Conservation, and Energy Act of 2008 was passed into law on May 22, 2008 with veto override votes in the House of Representatives and the Senate (House 2008). A difference between the 2002 and the 2008 bills is the newly instituted revenue-based counter-cyclical program called the Average Crop Revenue Election (ACRE) program available beginning crop year 2009. The ACRE program is offered as an alternative to the counter-cyclical payment (CCP) program that was in place during the 2002-2008 period. Beginning with the 2009 crop year, producers will have the option to enroll their farm in either the CCP program or the ACRE program. If ACRE is elected, producers cannot change program participation for the duration of the 2008 farm bill (ERS 2008). This is a very complex decision due to the number of variables that must be considered and depends on the individual farm situation. It requires that farms, rather than crops or commodities, enter the program, so that the decision relies on the impacts of program choice on farm income. That aside, understanding commodity situations is a first step toward understanding and making decisions on individual farm situations. The purpose of this briefing paper is to provide assistance in understanding the differences between the ACRE and CCP programs for one crop, cotton, in one state, Texas. The briefing paper will also show the results of a comparison between CCP and ACRE payments using a sample of actual farm data.

description: We investigate the possibility of measuring the primordial gravitational wave (GW) signal across 21 decades in frequencies, using the cosmic microwave background (CMB), pulsar timing arrays (PTA), and laser and atomic interferometers. For the CMB and PTA experiments we consider the LiteBIRD mission and the Square Kilometer Array (SKA), respectively. For the interferometers we consider space mission proposals including the Laser Interferometer Space Antenna (LISA), the Big Bang Observer (BBO), the Deci-hertz Interferometer Gravitational wave Observatory (DECIGO), the $μ$Ares experiment, the Decihertz Observatory (DO), and the Atomic Experiment for Dark Matter and Gravity Exploration in Space (AEDGE), as well as the ground-based Einstein Telescope (ET) proposal. We implement the mathematics needed to compute sensitivities for both CMB and interferometers, and derive the response functions for the latter from the first principles. We also evaluate the effect of the astrophysical foreground contamination in each experiment. We present binned sensitivity curves and error bars on the energy density parameter, $Ω_{GW}h^2$, as a function of frequency for two representative classes of models for the stochastic background of primordial GW: the quantum vacuum fluctuation in the metric from single-field slow-roll inflation, and the source-induced tensor perturbation from the spectator axion-SU(2) inflation models. We find excellent prospects for joint measurements of the GW spectrum by CMB and space-borne interferometers mission proposals.

description: Early season high winds and late season cool temperatures have worked together to limit the size of the High Plains cotton crop. Over the past 5 years, the High Plains2 has averaged 4.44 million bales produced each year. However, Plains Cotton Growers recently estimated the 2008 crop to be around 3.2 million bales (Wade). If these production numbers materialize, the 28% drop in production will have significant impacts on the regional economy. The purposes of this briefing paper are to: (1) estimate the impact of the cotton crop on the High Plains economy, and (2) estimate the impact of a smaller than average crop.
Dental phobia-Designing of training programs for patient care improvement in dentistry
Creators: name: Saada, Athar
Publisher: name: Zenodo

description: Title of Project Report: "How can Comprehensive Training Programs be Designed to Revitalize Dentistry, Alleviate Dental Phobia, and Improve Patient Care?" 

 Dental anxiety and phobia result in avoidance of dental care. It is a frequently encountered problem in dental offices. Formulating acceptable evidence-based therapies for such patients is essential, or else they can be a considerable source of stress for the dentist. These patients need to be identified at the earliest opportunity and their concerns addressed. The initial interaction between the dentist and the patient can reveal the presence of anxiety, fear, and phobia. In such situations, subjective evaluation by interviews and self-reporting on fear and anxiety scales and objective assessment of blood pressure, pulse rate, pulse oximetry, finger temperature, and galvanic skin response can greatly enhance the diagnosis and enable categorization of these individuals as mildly, moderately, or highly anxious or dental phobics. Broadly, dental anxiety can be managed by psychotherapeutic interventions, pharmacological interventions, or a combination of both, depending on the level of dental anxiety, patient characteristics, and clinical situations. Psychotherapeutic interventions are either behaviorally or cognitively oriented. Pharmacologically, these patients can be managed using either sedation or general anesthesia. Behavior-modification therapies aim to change unacceptable behaviors through learning, and involve muscle relaxation and relaxation breathing, along with guided imagery and physiological monitoring using biofeedback, hypnosis, acupuncture, distraction, positive reinforcement, stop-signaling, and exposure-based treatments, such as systematic desensitization, “tell-show-do”, and modeling. Cognitive strategies aim to alter and restructure the content of negative cognitions and enhance control over the negative thoughts. Cognitive behavior therapy is a combination of behavior therapy and cognitive therapy, and is currently the most accepted and successful psychological treatment for anxiety and phobia. In certain situations, where the patient is not able to respond to and cooperate well with psychotherapeutic interventions, is not willing to undergo these types of treatment, or is considered dental-phobic, pharmacological therapies such as sedation or general anesthesia should be sought.

description: The proposed 2007 farm bill contains fundamental shifts in policy option mainly dictated by a desire to render the U.S. agriculture “more market oriented’ and the programs less costly to the U.S. treasury. The proposal adopts a revenue-based counter cyclical payment while maintaining the current price-based counter cyclical payment scheme. Under the revenue-based system, payment would be triggered when the actual national revenue per acre falls below the national target revenue per acre. The choice is left to producers who will be allowed a one time option to select one of these two schemes.

description: New long Chandra grating observations of the O supergiant $ζ$ Pup show not only a brightening of the x-ray emission line flux of 13 per cent in the 18 years since Chandra's first observing cycle, but also clear evidence - at more than four sigma significance - of increased wind absorption signatures in its Doppler-broadened x-ray emission line profiles. We demonstrate this with non-parametric analysis of the profiles as well as Gaussian fitting and then use the line-profile model fitting to derive a mass-loss rate of $2.47 \pm 0.09 \times 10^{-6}$ Msun/yr, which is a 40 per cent increase over the value obtained from the cycle 1 data. The increase in the individual emission line fluxes is greater for short-wavelength lines than long-wavelength lines, as would be expected if a uniform increase in line emission is accompanied by an increase in the wavelength-dependent absorption by the cold wind in which the shock-heated plasma is embedded.
description: Accepted by MNRAS. No longer a letter, but rather a nine page paper with several multi-panel figures showing all the line profiles. We have now included an analysis of the entire cycle 19 data set and present two model-independent confirmations of the line profile changes

description: Lyotropic chromonic liquid crystals (LCLCs) represent aqueous dispersions of organic disk-like molecules that form cylindrical aggregates. Despite the growing interest in these materials, their flow behavior is poorly understood. Here, we explore the effect of shear on dynamic structures of the nematic LCLC, formed by 14wt ${\%}$ water dispersion of disodium cromoglycate (DSCG). We employ in-situ polarizing optical microscopy (POM) and small-angle and wide-angle X-ray scattering (SAXS/WAXS) to obtain independent and complementary information on the director structures over a wide range of shear rates. The DSCG nematic shows a shear-thinning behavior with two shear-thinning regions (Region I at $\dotγ<1\,s^{-1}$ and Region III at $\dotγ>10 s^{-1}$) separated by a pseudo-Newtonian Region II ($1 s^{-1}100 s^{-1}$, the texture evolves into periodic stripes in which the director is predominantly along the flow with left and right tilts. The period of stripes decreases with an increase of $\dotγ$. The shear-induced transformations are explained by the balance of the elastic and viscous energies. In particular, nucleation of disclinations is associated with an increase of the elastic energy at the walls separating nonsingular domains with different director tilts.
Bulk electron spin polarization generated by the spin Hall current

description: It is shown that the spin Hall current generates a non-equilibrium spin polarization in the interior of crystals with reduced symmetry in a way that is drastically different from the previously well-known equilibrium polarization during the spin relaxation process. The steady state spin polarization value does not depend on the strength of spin-orbit interaction offering possibility to generate relatively high spin polarization even in the case of weak spin-orbit coupling.

description: The United States has issued a proposal to the world trading community outlining several steps to jumpstart the stalled World Trade Organization (WTO) negotiations on agriculture. The proposal is intended as a challenge to members of the WTO to improve market access through “ambitious tariff reduction” and to “move aggressively” to cut trade-distorting domestic support (Portman, 2005). Although the major parameters of the proposal are yet to be defined, these steps seem consistent with commitments made by WTO participating countries to move agricultural trade negotiations forward in the framework agreement of July 2004.

description: Brazil made a formal complaint to the World Trade Organization (WTO) Dispute Settlement Panel against U.S. cotton programs in 2003, alleging that these subsidies depressed world cotton price and were injurious to Brazilian farmers. The petition was supported by Australia and West and Central African cotton producing countries. After long deliberations, the WTO appellate body came out with their final ruling in March 2005 that upheld most of the initial decisions of the WTO Dispute Settlement Panel. In addition to the finding of serious price suppressing effects of U.S. cotton programs during the period 1999/00-2002/03, the ruling also included a June 30, 2005 deadline to withdraw Step 2 and export credit guarantee programs. In an attempt to comply with the WTO findings, the United States Department of Agriculture (USDA) recently proposed legislative changes to modify credit guarantee fee structures for the GSM-102 and Supplier Credit Guarantee programs (SCGP) to a risk-based method and eliminate the Step 2 program.

description: Cotton is India’s main cash crop. It contributes to the livelihood of 60 million people and accounts for 30 percent of the country’s agricultural domestic product (Barwale et al., 2004). Total cotton acreage in India is estimated at 9 million hectares, the largest in the world (Gandhi, 2006). About 65 percent of cotton production activities are rainfed and subject to the vagaries of weather. Cotton is grown in nine states, spread over three agroclimatic zones with different planting schedules. Planting usually ends by the first week of June in northern regions (Punjab, Haryana, and Rajasthan), by mid-August in the central region (Gujarat, Maharashtra, and Madhya Pradesh), and by the first week of September in parts of the south (Andhra Pradesh, Karnataka, and Tamil Nadu). A small summer cotton crop in the south (Tamil Nadu) is planted in January and February (FAS, 2006).
Detection of point sources on two-dimensional images based on peaks

description: This article considers the detection of point sources in two dimensional astronomical images. The detection scheme we propose is based on peak statistics. We discuss the example of the detection of far galaxies in Cosmic Microwave Background experiments throughout the paper, although the method we present is totally general and can be used in many other fields of data analysis. We assume sources with a Gaussian profile --that is a fair approximation of the profile of a point source convolved with the detector beam in microwave experiments-- on a background modeled by a homogeneous and isotropic Gaussian random field characterized by a scale-free power spectrum. Point sources are enhanced with respect to the background by means of linear filters. After filtering, we identify local maxima and apply our detection scheme, a Neyman-Pearson detector that defines our region of acceptance based on the a priori pdf of the sources and the ratio of number densities. We study the different performances of some linear filters that have been used in this context in the literature: the Mexican Hat wavelet, the matched filter and the scale-adaptive filter. We consider as well an extension to two dimensions of the biparametric scale adaptive filter (BSAF). The BSAF depends on two parameters which are determined by maximizing the number density of real detections while fixing the number density of spurious detections. For our detection criterion the BSAF outperforms the other filters in the interesting case of white noise.

description: The Gaia optical observations are not the most suitable spectral domain for studying the low-mass, faintest and reddest part of the main sequence. Nevertheless, the large number of objects observed with an unprecedented precision, including trigonometric parallax, makes it an unrivaled dataset for studying the stellar-substellar boundary. In this paper, I review the contribution of the successive catalogues offered by the Gaia mission to study the low-mass, ultra-cool objetcs. I also present further characterisations and scientific exploitations of the Gaia sample.

Pretreatment and fermentation of Douglas-fir whitewood and bark feedstocks for ethanol production
Creators: name: Robinson, Jamie
Publisher: name: University of British Columbia
Year: 2009

description: As part of ongoing research to evaluate the bioconversion of softwood feedstocks to ethanol, the feasibility of using Douglas-fir residues was investigated. Whitewood feedstocks were pretreated using SC₂-catalyzed steam explosion under three pretreatment severity conditions (low, medium and high) with a goal of demonstrating efficient fermentation of the hemicellulose-rich water-soluble (WS) fraction. The chosen severity had a pronounced effect on the recovery of the hemicellulose sugars from the feedstock, as well as the proportion of monomeric sugars. Low-severity pretreatment resulted in the greatest recovery of hemicellulose sugars, with yields decreasing significantly for an increase in severity. Reduced-severity pretreatments also resulted in the recovery of fewer sugar decomposition products in the WS fraction, which translated into improved fermentation using an SSL-adapted strain of Saccharomyces cerevisiae. In contrast, the WS fraction obtained under high-severity conditions could not be fermented. Douglas-fir feedstocks containing bark (10, 20, 30 and 100% w/w) were pretreated under medium-severity to evaluate bark's impact on bioconversion. Bark had only a minor impact on the yield of hemicellulose sugars, with no negative effect on the monomeric sugar recovery. However, bark caused a significant decrease in the soluble sugar concentration. Process-derived fermentation inhibitors (e.g., furfural, HMF) also decreased, while naturally occurring inhibitors (e.g., lipophilic compounds) increased with greater bark loading. Despite this increase, bark had no detrimental impact on the rate of fermentation, and all hydrolysates were fermentable to high ethanol yield. Efforts to increase the low sugar concentration in the WS fractions were evaluated, in an attempt to increase the ethanol concentration recovered following fermentation. Increasing the sugar concentration in the WS fraction by physical means resulted in decreased rates of fermentation and reduced ethanol yields, even at low concentration factors (2- to 3-fold). As an alternative strategy, the sugar concentration in the WS fraction was augmented with carbohydrate derived from the water-insoluble cellulose component. Enzymatic hydrolysis of the cellulose component directly in the WS fraction proved unsatisfactory, due to inhibition by both carbohydrate and non-carbohydrate components. However, supplementation (1:1) of the WS fraction with the cellulose hydrolysate obtained separately in buffer provided improved sugar concentration, and significantly faster fermentation due to the effective dilution of inhibitors in the WS fraction. Using this approach, the initial hexose sugar concentration in the whitewood WS fraction was increased by 56%, and a final ethanol concentration of 23.4 g L⁻¹ was obtained.
