In other cases, neuropsychiatric symptoms present before surgery may be alleviated. Because application of diagnostic criteria for primary psychiatric disorders may not be valid in assessing behavior in epilepsy populations, we sought to determine the feasibility of measuring behaviors associated with frontalsubcortical dysfunction using the Frontal Systems Behavior Scale (FrSBe) in patients who had received surgical intervention for medically refractory epilepsy. Materials and methods: Twenty-three patients who had previously undergone epilepsy surgery and their family member informants completed the FrSBe. The FrSBe includes separate forms for patients and informants to rate symptoms associated with three frontal lobe syndromes – executive dysfunction, disinhibition, and apathy – prior to and following a neurological condition. Patients and informants were asked to rate frontal lobe behaviors before and after epilepsy surgery using the FrSBe. Results: Informants rated patients as showing a significantly greater reduction in apathy on the FrSBe compared to either disinhibition or executive dysfunction subscales. A trend in reduction of apathy following right hemisphere resection was found. Conclusions: Patients who have undergone epilepsy surgery show a reduction in apathy but it is unclear whether this behavioral change is directly related to the surgical intervention. We suggest that these preliminary findings support the utility of implementing dimensional scales such as the FrSBe to study behavioral changes following epilepsy surgery.

Automatic Entity Mapping for Scalable Data Exchange

Data Exchange creates an instance of a target schema from an instance of a source such that source data is reflected in the target instance. The approach for data transformation is based on mapping techniques and using schema mapping expressions representing high level relations between source and target. Data exchange is the process of taking data structured under a source schema, and generating an instance that adheres to the structure of a target schema. The prevailing approach for this process is based on schema mappings – high level specifications describing relationships between Source and Target areas. The mapping techniques unable to resolve ambiguous exchange scenarios and entity fragmentation . To address this problem, the proposed method based on mappings and privacy preserving data exchange that employs the best relations that can host source instances. The mapping method out forms other methods in terms of quality and scalability of data exchange and it improves the privacy during data exchange scenarios.
Simplified method for simulation of incompressible viscous flows inspired by the lattice Boltzmann method.

The lattice Boltzmann method (LBM) has gained increasing popularity in incompressible viscous flow simulations, but it uses many distribution functions (far more than the flow variables) and is often memory demanding. This disadvantage was overcome by a recent approach that solves the more actual macroscopic equations obtained through Taylor series expansion analysis of the lattice Boltzmann equations [Lu et al., J. Comput. Phys. 415, 109546 (2020)JCTPAH0021-999110.1016/j.jcp. 2020.109546]. The key is to keep some small additional terms (SATs) to stabilize the numerical solution of the weakly compressible Navier-Stokes equations. However, there are many SATs that complicate the implementation of their method. Based on some analyses and numerous tests, we ultimately pinpoint two essential ingredients for stable simulations: (1) suitable density (pressure) diffusion added to the continuity equation and (2) proper numerical dissipation related to the velocity divergence added to the momentum equations. Then we propose a simplified method that is not only easier to implement but noticeably faster than the original method and the LBM. It contains much simpler SATs that only involve the density (pressure) derivatives, and it requires no intermediate steps or variables. As well, it is extended for thermal flows with small temperature variations and for two-phase flows with uniform density and viscosity. Several test cases, including some two-phase problems under two-dimensional, axisymmetric, and three-dimensional geometries, are presented to demonstrate its capability. This work may help pave the way for the simplest simulation of incompressible viscous flows on collocated grids based on the artificial compressibility methodology.
Specific Solvent Produces Specific Phase Ni Nanoparticles: A Pulsed Laser Ablation in Solvents

In this paper, we present a simple and controllable preparation of face centered cubic (fcc) and hexagonal close-packed (hcp) Ni nanoparticles by a pulsed Nd:YAG laser ablation method in the following four solvents: deionized water, methanol, hexane, and acetonitrile. We generated Ni/NiO, fcc, and/or hcp Ni nanoparticles by primary ablation to a Ni plate submerged in various solvents, followed by secondary ablation to the colloidal solutions. Interestingly, the phases of Ni nanoparticles prepared via a pulsed laser ablation in liquid (PLAL) show a strong dependence on the solvents used in the ablation processes. Ni/NiO, pure fcc, and a mixture of fcc and hcp Ni nanoparticles were generated in DI water, methanol, and hexane or acetonitrile, respectively. After secondary ablation, however, pure fcc Ni nanoparticles were generated in methanol and hexane, while pure hcp Ni was formed in acetonitrile. We think that the solvent dependence on the phase of Ni nanocrystals is related to the specific heat of solven.

Background The aims of this study were to assess whether deprivation inequality at small area level in England is associated with coronary heart disease (CHD) mortality rates and to assess whether this provides evidence of an association between area-level and individual-level risk. Methods Mortality rates for all wards in England were calculated using all CHD deaths between 2001 and 2006. Ward-level deprivation was measured using the Carstairs Index. Deprivation inequality within local authorities (LAs) was measured by the IQR of deprivation for wards within the LA. Relative deprivation for wards was measured as the modulus of the difference between deprivation for the ward and average deprivation for all
Monte Carlo estimators for differential light transport

Physically based differentiable rendering algorithms propagate derivatives through realistic light transport simulations and have applications in diverse areas including inverse reconstruction and machine learning. Recent progress has led to unbiased methods that can simultaneously compute derivatives with respect to millions of parameters. At the same time, elementary properties of these methods remain poorly understood. Current algorithms for differentiable rendering are constructed by mechanically differentiating a given primal algorithm. While convenient, such an approach is simplistic because it leaves no room for improvement. Differentiation produces major changes in the integrals that occur throughout the rendering process, which indicates that the primal and differential algorithms should be decoupled so that the latter can suitably adapt. This leads to a large space of possibilities: consider that even the most basic Monte Carlo path tracer already involves several design choices concerning the techniques for sampling materials and emitters, and their combination, e.g. via multiple importance sampling (MIS). Differentiation causes a veritable explosion of this decision tree: should we differentiate only the estimator, or also the sampling technique? Should MIS be applied before or after differentiation? Are specialized derivative sampling strategies of any use? How should visibility-related discontinuities be handled when millions of parameters are differentiated simultaneously? In this paper, we provide a taxonomy and analysis of different estimators for differential light transport to provide intuition about these and related questions.
POINTS OF QUANTUM SLn COMING FROM QUANTUM SNAKES

We show that the quantized Fock-Goncharov monodromy matrices satisfy the relations of the quantum special linear group SLn. The proof employs a quantum version of the technology invented by Fock-Goncharov called snakes. This relationship between higher Teichmüller theory and quantum group theory is integral to the construction of a SLn-quantum trace map for knots in thickened surfaces, developed in [Dou21]. For a finitely generated group Γ and a suitable Lie group G, a primary object of study in low-dimensional geometry and topology is the G-character variety RG(Γ) = {ρ : Γ −! G} / G consisting of group homomorphisms ρ from Γ to G, considered up to conjugation. Here, the quotient is taken in the algebraic geometric sense of Geometric Invariant Theory [MFK94]. Character varieties can be explored using a wide variety of mathematical skill sets. Some examples include the Higgs bundle approach of Hitchin [Hit92], the dynamics approach of Labourie [Lab06], and the representation theory approach of Fock-Goncharov [FG06b]. In the case where the group Γ = π1(S) is the fundamental group of a punctured surface S of finite topological type, and where the Lie group G = SLn(C) is the special linear group, we are interested in studying a relationship between two competing deformation quantizations of the character variety RSLn(C)(S) := RSLn(C)(π1(S)). Here, a deformation quantization {R}q of a Poisson space R is a family of non-commutative algebras R parametrized by a nonzero complex parameter q = e2πi~, such that the lack of commutativity in R is infinitesimally measured in the semi-classical limit ~ ! 0 by the Poisson bracket of the space R. In the case where R = RSLn(C)(S) is the character variety, the bracket is provided by the Goldman Poisson structure on RSLn(C)(S) [Gol84, Gol86]. The first quantization of the character variety is the SLn(C)-skein algebra Sn(S) of the surface S; see [Tur89, Wit89, Prz91, BFKB99, Kup96, Sik05]. The skein algebra is motivated by the classical algebraic geometric approach to studying the character variety RSLn(C)(S) via its commutative algebra of regular functions C[RSLn(C)(S)]. An example of a regular function is the trace function Trγ : RSLn(C)(S) ! C associated to a closed curve γ ∈ π1(S) sending a representation ρ : π1(S) ! SLn(C) to the trace Tr(ρ(γ)) ∈ C of the matrix ρ(γ) ∈ SLn(C). A theorem of Classical Invariant Theory, due to Procesi [Pro76], says that the trace functions Trγ generate the algebra of functions C[RSLn(C)(S)] as an algebra. According to the philosophy of Turaev and Witten, quantizations of the character variety should be of a 3-dimensional nature. Indeed, elements of the skein algebra Sn(S) are represented by knots (or links) K in the thickened surface S × (0, 1). The skein algebra Sn(S) has the advantage of being natural, but is difficult to work with in practice. Date: June 18, 2021.

Hypothesis: Sam68 and Pygo2 mediate cell type-specific effects of the modulation of CBP-Wnt and p300-Wnt activities in Colorectal Cancer Cells

The preventive activity of dietary fiber against colorectal cancer (CRC) may be in part mediated by the fermentation product of fiber, butyrate, a histone deacetylase inhibitor (HDACi) that induces CRC cell growth arrest and apoptosis. This action of butyrate, and other HDACis, is in part due to the hyperactivation of the deregulated Wnt activity found in the relevant CRC cell lines. The histone acetylases CBP and p300 interact with beta-catenin; and the relative levels of CBP-Wnt vs. p300-Wnt activity influences CRC cell physiology. It has previously been observed that there are cell type-specific differences in how cotreatment with butyrate and ICG-001, an agent that blocks CBP-Wnt activity allowing for p300-Wnt activity, affects CRC cell physiology. These differences may have clinical significance in dealing with treatment of CRC patients with ICG-001-like agents. Sam68 is a factor differentially expressed in cancer cells, with higher expression in cancer cell lines that have cancer stem cell (CSC)-like properties. Sam68 expression sensitizes cancer cells to ICG-001 treatment, as ICG-001 enhances nuclear localization of Sam68, where binding between Sam68 and CBP diminishes CBP-beta-catenin binding and thus CBP-Wnt activity. Pygo2 is a chromatin effector involved with Wnt signaling that is differentially acetylated by CBP and p300; thus CBP-mediated acetylation localized Pygo2 to the nucleus where it functions in transcriptional activation, while p300-mediated acetylation localizes Pygo2 to the cytoplasm. This paper proposes the hypothesis that Sam68 and Pygo2 are responsible for cell type-specific response of CRC cell lines cotreated with ICG-001 and butyrate as well as other HDACis. Further, experiments are proposed to evaluate this hypothesis and consider possible expected results that could be obtained from such studies.
XXI SIMPÓSIO NACIONAL DE BIOPROCESSOS XII SIMPÓSIO DE HIDRÓLISE ENZIMÁTICA DE BIOMASSA

Microalgae are gaining attention as a potential source of fermentable sugars, since some species can accumulate high contents of intracellular starch. Therefore, the aim of this work was to study the enzymatic hydrolysis of the starch-rich green microalga Chlorella sorokiniana. Enzymatic and physical methods were evaluated for the disruption of the microalga's cell wall, and it was found that cellulases were not effective in disrupting this structure. After milling, the intracellular starch was easily hydrolyzed by fungal amylases without a gelatinization step, with a final glucose yield of 99 % after only 5 hours of hydrolysis. It was possible to increase the solids loading up to 25 % (m/m), promoting an increase of 350 % in the final glucose concentration with a yield loss of only 24 %.
Children’s reading on screens: how do children make meaning from digital books and

In alignment with contemporary theoretical models of reading on screen, this review suggests avenues for future multi-method research by drawing on psychological as well as socio-cultural aspects of reading. Experimental and meta-analytical studies can help develop a more refined understanding of the added value of specific new features in digital books. The key contribution of qualitative studies is the theoretical extension they provide to cognitive models of reading, including the focus on socio-emotional outcomes and corporal responses to texts. Interdisciplinary approaches can provide complementary perspectives and convergent recommendations issued to children’s publishing industry and adults mediating their use.
AN ABSTRACT OF THE THESIS OF

approved: , | . Michael H. Penner The movements of digestion markers in the gut of the rat were investigated and the results of the investigation are reported in two manuscripts. The objective of the first study was to determine the influence of particle size of dietary wheat bran, chosen as a representative insoluble fiber, on the mean retention time (MRT) of digesta in the rat. The study design included a control group to detect the influence of particle size of digestion marker on the observed retention times. Additionally, a comparison was made between bran and the soluble fiber pectin. Both the soluble cobalt EDTA (Co EDTA) and insoluble chromium mordanted bran (CrMB), of two size ranges were administered to 4 groups of rats fed a semi-purified diet supplemented with wheat bran or pectin (10% dilution). Bran size and paniculate marker size were large/large, large/small, small/small and pectin/small for the 4 groups. Mean retention times for CrMB were significantly longer in the pectin than the bran supplemented groups. Differences were not significantly different within the bran supplemented group. No significant differences were found between the rate of passage of CrMB and Co EDTA in any group. The second study was designed to identify pooling of markers in the rat gut. A mathematical model was developed as a system of equations which predicted the marker distribution along the gut following dosing. The model assumed that two pools, the stomach and cecum, were kinetically recognizable in the rat. The predicted distribution of CrMB and Co EDTA was compared to in vivo distribution at 4 h intervals by sequential termination and dissection of the animals. The smaller particle bran had a longer MRT in the cecum and a shorter MRT in the proximal colon. Total MRT to the mid-colon was similar in all bran supplemented groups. Pectin fed animals had significantly enlarged gut organs which explained the slower movement of marker in these animals. The cecum was found to delay the transit of marker from the small intestine to the proximal colon as much as 2.1 h. This delay resulted in the gut appearing as a single pool overall and therefore led the model to overpredict the initial rate of appearance of marker distal to the cecum. A streamlined system was developed to digest the fecal samples in preparation for atomic absorption spectroscopy, the method used to quantify digestion marker recovery. The development of the method is discussed and supporting data are presented on the reproducibility and limits of the method. Digesta Passage Rates in the Rat
Evaluation of the Effect of Surgical Extraction of an Impacted Mandibular Third Molar on the Periodontal Status of the Second Molar—Prospective Study

Dental injury to the second molar (SM) caused by the surgical extraction of the impacted third molar tends to be underestimated. The necessity of assessment of the impact of the removal of the wisdom tooth in the mandible on the second molar arose. The study group (n = 60) was the one with the second molar on the surgical side, and the control group (n = 60) was the one with the tooth on the opposite side of the alveolar arch. Before the surgery, the difficulty level was assessed according to the Pederson scale. The periodontal status of the SM was assessed by probing depth (PD), gingival index (GI), tooth mobility (TM) examination by the percussion method and resonance frequency. Measurements were taken before and after the surgery, 7 days and 8 weeks after the surgery. The study demonstrated the significant impact of the surgical removal of the wisdom tooth on the PD, GI and TM of the SM. The predicted degree of difficulty of the very difficult surgery had an influence on the increase in PD on the distal buccal and lingual surface of the SM, and on the GI in the proximity of the examined tooth. The results of the presented research confirm the necessity of the clinical assessment of the lower SM before and after the surgical removal of the impacted wisdom tooth in the mandible.
Job Demands-Control model and employees’ mental health: The mediate role of work-family conflict

This paper has two goals: examine the effect of job characteristics proposed in the Job DemandsControl (JDC) model on work-family conflict (WFC) and the effect of this variable on employees’ mental health; examine the mediate role of WFC between these job characteristics and employees’ mental health. The hypotheses, using structural equation modeling, were tested with cross-lagged analyses based on two waves over a 6-months period in a sample of 958 employees with different functions in a Portuguese organization from service sector. The findings show that job demands are significant in determining WFC, which in turn mediates the relationship between these job characteristics and employees’ mental health six months later. No relationship is found between job control and WFC. The paper highlights the relevance to intervene on job demands and WFC to control employees ́ mental health.
Investigating mechanical properties of biopolymers

Cellular movements depend on the rearrangement of the interconnected networks of biopolymers. To understand cellular movements like e.g. cell division we need to describe the mechanical properties of the biopolymers involved in these processes. The aim of this thesis was to describe the mechanics of two polymeric structures: i) a single DNA molecule and ii) a higher order assembly of microtubules crosslinked by kinesin-14, HSET, molecular motors. We used a combination of direct manipulation and force measurement by the optical tweezers with imaging of single molecules by fluorescence microscopy. We confirmed that the elastic behaviour of a single λ-DNA molecule follows the wormlike chain model and that the molecule over-stretches at ~65 pN. We found that HSET crosslinks and slides microtubules and that this sliding stalls when the microtubules start to separate. We show that the stopping is due to an entropic force generated by HSET molecules confined in the overlap between the microtubules. We quantified the entropic force to be in the pN range, reaching up to ~20pN. Our results represent a novel insight into the functioning of molecular motors in context of biopolymer assemblies and will be used to further describe the biopolymer structures of higher complexities.
