Abstract:

A few approaches have studied image fusion using color-plus-mono dual cameras to improve the image quality in low-light shooting. Among them, the color transfer approach, which transfers the color information of a color image to a mono image, is considered to be promising for obtaining improved images with less noise and more detail. However, the color transfer algorithms rely heavily on appropriate color hints from a given color image. Unreliable color hints caused by errors in stereo matching of a color-plus-mono image pair can generate various visual artifacts in the final fused image. This study proposes a novel color transfer method that seeks reliable color hints from a color image and colorizes a corresponding mono image with reliable color hints that are based on a deep learning model. Specifically, a color-hint-based mask generation algorithm is developed to obtain reliable color hints. It removes unreliable color pixels using a reliability map computed by the binocular just-noticeable-difference model. In addition, a deep colorization network that utilizes structural information is proposed for solving the color bleeding artifact problem. The experimental results demonstrate that the proposed method provides better results than the existing image fusion algorithms for dual cameras.

Abstract:

In SMT production line, different types of components may have the same shape but providing different functions. The only difference between these components is the text on surface of a component indicating its type. Therefore, not only geometry defect inspection but also text detection is needed in component inspection to avoid wrong use of components. Traditional algorithms based on pixel comparison of text image are time consuming and sensitive to tiny change of the text as well. A concise text detection algorithm based on color projection is proposed. The algorithm transfers two-dimensional color image to one-dimensional curve for comparison by projection of the text image, which greatly reduces the computing amount, increases speed and makes the algorithm less sensitive to displacement or rotation of the text. Experiments show that the algorithm can ensure effective real-time text detection.

Abstract:

We propose a practical cartoon image retrieval scheme to retrieve cartoon images efficiently. The proposed scheme transfers each cartoon image to a color sequence using straightforward 8 rules. Subsequently, using the color sequences to compare the cartoon images, namely color sequences comparison. We succeed in transferring the cartoon image retrieval problem to sequences comparison. Thus the computational complexity is decreased obviously. Our system keeps both advantages of the content based cartoon image retrieval system (similarity-based retrieval) and a text based cartoon image retrieval system (very rapid and mature).

Abstract:

A complete theory is the guide and explanation of the experiment. According to the first principle, the stable structure of Ge vacancy color center (GeV) is the double vacancy center structure by using the constructed GeV color center supercell. The covalent radius and bond angle of GeV are explored by analyzing the microstructures. The electronic structure of GeV color center is calculated, and the charge transfers of GeV color center are explained, thereby demonstrating the existence of stable bonds. The principle of the energy-level transition of the GeV color center in terms of light emission is described. The effect of each element and energy level orbital is illustrated by the density-of-states diagram.

Abstract:

Instead of gametes, ovaries could be used as alternative resources for cryopreservation. In this study, we attempted to produce pups by transplantation of fresh ovaries to foster mothers as a first step to establish a preservation method of hamster strains on the basis of the cryopreservation of ovaries in combination with ovarian transfers. We also checked the possibility of inter-strain transfers of ovaries, since immunological tolerance among hamster strains is suggested by the fact that most Syrian hamsters were derived from only a small number of animals. Fresh ovaries collected from 3-weekold females of HAW (white coat) and APA (albino) strains were transferred into ovarian bursae of 3-week-old recipient females with agouti-coat (Slc:Syrian) under anesthesia with xylazine and ketamine. Halves of ovaries of recipients were removed immediately before the transfers, i.e., both donor and recipient ovaries were present in each ovarian bursa. Successful transplantation of ovaries was checked by the coat color (non-agouti color) of offspring produced by test matings of recipients with Slc:Syrian males after the recipients became mature. Five and six recipients received HAW and APA ovaries, respectively. All 11 recipients tested became pregnant and delivered pups. According to the coat color of the pups, three of five recipients which received HAW ovaries and one of six recipients which received APA ovaries delivered pups derived from transplanted ovaries (two out of eight pups, one out of seven pups, and three out of 11 pups for HAW; one out of five pups for APA). Our results indicate that transplantation of fresh ovaries to foster mothers could be used for production of pups from grafted ovaries in the Syrian hamster. In particular, immunological tolerance for ovarian transfers among at least three strains suggests that recipient strains might not need to be the same as donor strains for practical ovarian transfers in the Syrian hamster. Our results would facilitate the development of a strain preservation system for the Syrian hamster based on ovarian cryopreservation. This work was supported by a grant from the Ministry of Health, Labor, and Welfare of Japan.

Abstract:

In the current research, we posited the stigma-by-prejudice-transfer effect, which proposes that stigmatized group members (e.g., White women) are threatened by prejudice that is directed at other stigmatized group members (e.g., African Americans) because they believe that prejudice has monolithic qualities. While most stigma researchers assume that there is a direct correspondence between the attitude of prejudiced individuals and the targets (i.e., sexism affects women, racism affects racial minorities), the five studies reported here demonstrate that White women can be threatened by racism (Study 1, 3, 4, and 5) and men of color by sexism (Study 2). Robust to perceptions of liking and the order in which measures were administered, results showed that prejudice transfers between racism and sexism were driven by the presumed social dominance orientation of the prejudiced individual. In addition, important downstream consequences, such as the increased likelihood of anticipated stigma, expectations of unfair treatment, and the attribution of negative feedback to sexism, appeared for stigmatized individuals.

Abstract:

Compositionally similar organic red colorants in the anthraquinone family, whose photodegradation can cause irreversible color and stability changes, have long been used in works of art. Different organic reds, and their multiple chromophores, suffer degradation disparately. Understanding the details of these molecules’ degradation therefore provides a window into their behavior in works of art and may assist the development of improved conservation methods. According to one proposed model of photodegradation dynamics, intramolecular proton transfer provides a kinetically favored decay pathway in some photoexcited chromophores, preventing degradation-promoting electron transfer (ET). To further test this model, we measured excited state lifetimes of substituted gas-phase anthraquinones using high-level theory to explain the experimental results. The data show a general structural trend: Anthraquinones with 1,4-OH substitution are long-lived and prone to damaging ET, while excited state intramolecular proton transfers promote efficient quenching for hydroxyanthraquinones that lack this motif.

Abstract:

We establish a nonlinear version of the SU(N)-symmetric theory, which describes self-consistently the interaction between the gravitational, gauge, vector and pseudoscalar (axion) fields. In the context of this theory the SU(N)-symmetric multiplet of vector fields is associated with the color aether, the decay of which in the early Universe produced the canonic dynamic aether and the axionic dark matter. The SU(N)-symmetric Yang–Mills field, associated with the color aether, forms the source, which transfers the energy of the decaying color aether to the axion field. The nonlinear modification of the model uses explicitly the requirement of discrete symmetry, prescribed by the axion field, and is based on the analogy with a nonlinear physical pendulum. We show that in the framework of this nonlinear regular model, the axion field can grow to an arbitrarily large value, thus explaining the abundance of the axionic dark matter in the Universe.

Abstract:

This article highlights the next generation of can decorating machines by packagers and the manufacturers of packaging machinery. To build their new next-generation decorator, Alcoa Packaging Machinery’s (APM) engineers were given the rare opportunity to develop the machine from a “white sheet.” The four-color decorator is a continuous-motion, rotary machine, which holds each can body upright on a mandrel. Each can rolls against a blanket cylinder, which transfers an inked pattern from a plate cylinder. APM’s engineers were especially interested in finding out how the mandrel shafts would deflect under load. Deflection is an important consideration for any rotary printer because it determines how well an image will transfer between rolls. APM is planning to unveil its new can decorator at a metal packaging trade show in Germany. The machine has yet to be proven in production, but the design has progressed.

Abstract:

Student enrollment and transfer patterns between the traditional public and charter school sectors help shape the role of charter schools in the broader educational ecosystem, especially as related to the enrollment and segregation of low-income students, English learners, students of color, and students in special education. We examine patterns of student transfer between traditional public schools and charter schools among four of Texas’s largest charter networks, which cumulatively make up over one-third of Texas charter students. We find that these schools serve fewer special education students than traditional public schools, but a greater share of low-income and English learners. Transfers between sectors contribute to enrollment gaps in special education and other classifications, but the findings do not apply uniformly across charter districts, student enrollment classifications, or grade levels. These findings highlight nuanced enrollment patterns between the charter sector and traditional public schools, suggesting that differences in student characteristics between sectors likely stem from a range of sources. Policymakers should acknowledge this nuance, consider alternatives to blanket enrollment regulation policies, and conduct similar analyses of enrollment patterns among charter districts.

Abstract:

We study heavy-flavor hadron production in high-energy pp collisions, assuming the formation of a small, deconfined and expanding fireball where charm quarks can undergo rescattering and hadronization. We adopt the same in-medium hadronization mechanism developed for heavy-ion collisions, which involves Local Color-Neutralization (LCN) through recombination of charm quarks with nearby opposite color charges from the background fireball. Diquark excitations in the hot medium favor the formation of charmed baryons. The recombination process, involving closely aligned partons from the same fluid cell, effectively transfers the collective flow of the system to the final charmed hadrons. This framework can qualitatively reproduce the observed experimental findings in heavy-flavor particle-yield ratios, pT -spectra and ellipticflow coefficients. Our results provide new, complementary support to the idea that the collective phenomena observed in small systems have the same origin as those observed in heavy-ion collisions.

Abstract:

The Y2O2S:Er3+@Y2O2S:Yb3+,Ho3+ core-shell up-conversion (UC) nanoparticles were successfully synthesized by the homogeneous co-precipitation method. The Y2O2S:Er3+@Y2O2S:Yb3+,Ho3+ core-shell nanoparticles exhibit bright green emissions under 980 nm excitation, while the triple-ion doped Y2O2S:Er3+,Yb3+,Ho3+ sample presents mainly red emissions. The intensity ratio of green-to-red emission of the core-shell and conventional triple-ion doped samples are 2.8 and 0.3, respectively. Investigations on the UC mechanisms show that emissions from Er3+ and Ho3+ ions are achieved simultaneously in the core-shell nanoparticles. This is due to the efficient energy transfers of Yb3+→Ho3+ within the shell layer and Yb3+→Er3+ between the shell and the core. While the triple-ion doped Y2O2S: Er3+,Yb3+,Ho3+ sample exhibits mainly the emissions of Er3+ along with weak luminescence of Ho3+ ion. Since the cross relaxation between Er3+ and Ho3+ ions in the Y2O2S:Er3+,Yb3+,Ho3+ nanoparticles can effectively suppress the emissions of Ho3+ ions. Yet, in the core-shell structure, this cross relaxation can be successfully restrained in the core-shell structure where Er3+ is in the core and Ho3+ is in the shell. Therefore, the construction of core-shell structure can improve the luminescence efficiency and provide a route for adjustment of emission color.

Abstract:

There is a growing trend among developed countries to increase the participation of youth in societal and institutional decision-making. The challenge is to move away from an illusion of participation (tokenism) to genuine youth influence. This article transfers knowledge of a relatively new theory to the fields of youth engagement and community development. We pose deliberative democracy as a model to build bridges between youth and decision-makers. This concrete approach offers a platform for youth and adults to engage in a learning process as equal citizens and proactive leaders. Deliberative democracy can be understood as an umbrella term for different models of public deliberation. These models attempt to create carefully detailed conditions for increasing the legitimacy of decisions made through deliberation. Deliberative models that feature youth participation include youth juries, dialogue days between young people and decision-makers, and adult-youth participatory forums where the youth voice is usually a minority. We explore the role of relationships, collaboration, and leadership in generating democratic spaces for the inclusion of youth in policy formation and reform. The challenges associated with engaging youth are discussed along with examples of models from Australia, Finland, Canada, and the United States that promote effective youth engagement.

Abstract:

The dynamical question is raised of the possible existence of long-range, residual attractive forces between hadrons due to the overall color-neutral exchange of two, massless transverse gluons between their constituents. Such a force between fermionic constituents would behave as 1/R6. We discuss the experiments which measure the real part of the nuclear amplitude, through its interference with the Coulomb amplitude in high energy [Formula: see text] elastic scattering at very small momentum transfers. We show that on-going [Formula: see text] experiments at [Formula: see text] and at 1800 GeV are sensitive to the scattering amplitude from a residual long-range force.

Abstract:

Swine production requires a stable health status that can be compromised by introduction of live animals for genetic change. Our objective was to use embryo transfer to avoid disease transmission during genetic relocation. Forty genotype-specific (GS) donor females were scheduled for 3 sessions of embryo recovery at 6-week intervals using Altrenogest (Matrix®, Intervet, Millsboro, DE), 1250 IU of equine chorionic gonadotropin (eCG/PMSG; Sigma, St. Louis, MO) and 750 IU of human chorionic gonadotropin (hCG; Chorulon®, Intervet). Single-sire GS matings were made 34 h after Chorulon® injection. To accomplish single-sire transfers, color specific (CS) supplemental embryos were used to assist in maintenance of recipient pregnancy. The CS embryo donors and GS embryo recipients were synchronized with Matrix®, P.G. 600® (200 IU hCG, 400 IU PMSG, Intervet) and Chorulon®. Embryos from GS donors were surgically recovered on Day 5 post-insemination, washed per IETS recommendations using a zwitterion-buffered culture medium (PorcPro E-Blast, Minitube of America, Verona, WI) and transported in a portable incubator (Minitube of America) 2.5 h to the recipient herd. Embryos were surgically transferred into –24-h asynchronous recipients within 6 to 14 h after recovery. A total of 620 embryos were recovered from 65.2% (60/92) of GS matings, and 587 (59.4%) GS and 402 (40.6%) CS embryos were transferred into 63 recipients. On average, 9.3 GS and 6.4 CS embryos were transferred per recipient (15.7). A total of 33 GS embryos were discarded before transfer. To achieve a target of 17 embryos per transfer, 59 embryo transfers required CS embryos and 4 embryo transfers were only GS embryos. Fifty-three (84.1%) recipients were confirmed pregnant by ultrasound at 35 days of gestation. Of the 40 GS donors, one was culled for genetic reasons, 6 did not give transferable embryos, and 1 gave transferable embryos but the corresponding recipient returned to estrus for a total genetic transfer rate of 80% (32/40). After 3 sessions of embryo transfer, 32/33 (97%) GS donors that produced embryos for transfer were represented by a minimum of 1 pregnant recipient at 35 days of gestation; 17/32 GS donors were represented by a single pregnancy and 15/32 by multiple pregnancies. Sera from GS donors were evaluated for porcine reproductive and respiratory syndrome (PRRSV) and porcine circovirus type 2 (PCV2) before each embryo recovery session. Serology results were negative for PRRS (0/98)) and positive for PCV2 in 27.5% (27/98) of GS donors. Embryo wash media from the last 2 washes from PCV2 positive GS donors producing embryos for transfer were pooled and evaluated for PCV2 after transfer; all samples (0/18) were negative for PCV2. In summary, zona pellucida-intact embryos were successfully used to relocate swine genetics from a donor herd into a recipient herd with no apparent health status change in the recipient herd.

Abstract:

Summary: The lumbosacral plexus is the network of nerves responsible for the motor and sensory function of the pelvis and lower limb. Our observation is that the anatomy of this plexus is less familiar to surgeons than that of the brachial plexus. Damage to the lumbosacral plexus and its terminal branches may have a significant impact on locomotion, posture, and stability. We have designed a visual representation of the lumbosacral plexus to aid clinicians treating peripheral nerve disorders. The utility is illustrated with a case report in which a patient underwent nerve transfers in the lower limb to restore function. A visual representation of the lumbosacral plexus is a valuable adjunct to a clinical examination and helps make sense of clinical signs. The color-coding of each root level and the arrangement of muscles from proximal to distal helps with visual recall. A clear assessment of complex lumbosacral plexus patients is essential for diagnosis and planning. As with the case described, a sound knowledge of the “plexogram” can identify solutions for complex patients and result in significant functional improvements. We hope it helps advance the field of nerve surgery and, particularly, nerve transfers.

Abstract:

100 Background: Colorectal cancer disparities loom large for underserved communities of color in the US where barriers to screening uptake can contribute to late-stage diagnosis and poor outcomes. Despite active outreach by skilled patient navigators (PN) at a NYC cancer center serving an ethnically minoritized and disadvantaged population, 59% (1,925/3,276) of patients either cancelled or did not show for their colonoscopy appointments in 2022. While PN re-engagement efforts led to 410 (21%) completing colonoscopy, 1,500 patients did not undergo potentially life-saving colon cancer screening that year. With the advent of conversational Artificial Intelligence (AI)-driven applications within health care offering a potential extension to a stretched workforce, our cancer center examined the use of an AI-based virtual patient navigator, MyEleanor, as part of a colorectal cancer screening quality improvement (QI) project. Methods: This QI project employed MyEleanor between Apr-Dec 2023 to target re-engagement of 2,400 patients nonadherent with colonoscopy appointments in 2022-2023. In place of human PNs, MyEleanor (a) called patients to discuss rescheduling, (b) assessed barriers to uptake, c) offered live transfers to clinical staff to reschedule, and d) provided procedure prep reminder calls. Evaluable outcomes included: (a) engagement with MyEleanor via identity confirmation, (b) live transfers accepted (actionable), (c) colonoscopy completion rate, and (d) patient volume, with (d) barriers to care, and (e) predictors of actionable engagement examined. Results: Over 8 months, 57% (1,368/2,400) of patients engaged with MyEleanor, with 58% (789) of this group, or 33% overall, accepting the live transfer. The completion rate for patients who did not show for initial appointment nearly doubled from 10% to 19% from 2022 to 2023 (pre to post-MyEleanor). Overall patient volume increased by 36%. Patients who engaged were a Mean age of 56.66 (41-79 yrs), female (66%), Hispanic (41%), Black (33%), English (73%) or Spanish (25%) speaking, and partnered (37%). Nearly one third reported at least two barriers to screening; top barriers included lack of perceived need (19%), time (18%), and MD encouragement (16%), medical mistrust (14%), and concerns about findings (13%) and cost (12%). Greater number of barriers predicted actionable engagement, (F(1366) = 354, p < 0.001), with Spanish-dominant patients and those declining to identify their race reporting nearly twice the number of barriers, F(1366) = 138.98 and F(1366) = 5.17, p < 0.001, respectively). Conclusions: This project demonstrates high potential of an AI patient navigator in helping to overcome patient attrition that can lead to colon cancer disparities while improving patient volume. Next phase of the project will examine impact on patient prep adherence, staff burden, and revenue.

Abstract:

Abstract The Temporary Assistance for Needy Families (TANF) program is a federal block grant to the states, with a required state contribution. Although often viewed as a cash assistance program with work requirements and services targeted at extremely low-income families with children, only about one-quarter of all state and federal TANF funds are now used for traditional cash aid. Uses of funds vary widely by state, and alternatives range from refundable tax credits to support of state child welfare systems. In this article, the author examines the relationship between state categorical TANF spending and key social, political, and economic characteristics using data from 2015 to 2017 and multilevel linear models. Racial and ethnic demographics of the cash assistance caseload are associated with differences in spending, with states with larger proportions of the caseload composed of people of color devoting a lower percentage of effort to traditional benefits and more to alternative cash transfers. Changes in unemployment rate within states are associated with greater spending on basic assistance and reduced spending on alternative transfers. These findings indicate that, although TANF cash benefits spending may be economically responsive within the program’s overall flexible structure, spending patterns raise issues of equity for disadvantaged families.

Abstract:

Aims. We study the surface of Ceres at visible wavelengths, as observed by the Visible and InfraRed mapping spectrometer (VIR) onboard the Dawn spacecraft, and analyze the variations of various spectral parameters across the whole surface. We also focus on several noteworthy areas of the surface of this dwarf planet. Methods. We made use of the newly corrected VIR visible data to build global maps of a calibrated radiance factor at 550 nm, with two color composites and three spectral slopes between 400 and 950 nm. We have made these maps available for the community via the Aladin Desktop software. Results. Ceres’ surface shows diverse spectral behaviors in the visible range. The color composite and the spectral slope between 480 and 800 nm highlight fresh impact craters and young geologic formations of endogenous origin, which appear bluer than the rest of the surface. The steep slope before 465 nm displays very distinct variations and may be a proxy for the absorptions caused by the O2− → Fe3+ or the 2Fe3+ → Fe2+ + Fe4+ charge transfers, if the latter are found to be responsible for the drop in this spectral range. We notice several similarities between the spectral slopes and the abundance of phyllosilicates detected in the infrared by the VIR, whereas no correlation can be clearly established with carbonate species. The region of the Dantu impact crater presents a peculiar spectral behavior – especially through the color and the spectral slope before 465 nm – suggesting a change in composition or in the surface physical properties that is not observed elsewhere on Ceres.

Abstract:

Observation of the onset of color transparency in baryons would provide a new means of studying the nuclear strong force and would be the first clear evidence of baryons transforming into a color-neutral point-like size in the nucleus as predicted by quantum chromodynamics. Recent C(e,e′p) results from electron-scattering did not observe the onset of color transparency (CT) in protons up to spacelike four-momentum transfers squared, Q2=14.2 GeV2. The traditional methods of searching for CT in (e,e′p) scattering use heavy targets favoring kinematics with already initially reduced final state interactions (FSIs) such that any CT effect that further reduces FSIs will be small. The reasoning behind this choice is the difficulty in accounting for all FSIs. D(e,e′p)n, on the other hand, has well-understood FSI contributions from double scattering with a known dependence on the kinematics and can show an increased sensitivity to hadrons in point-like configurations. Double scattering is the square of the re-scattering amplitude in which the knocked-out nucleon interacts with the spectator nucleon, a process that is suppressed in the presence of point-like configurations and is particularly well-studied for the deuteron. This suppression yields a quadratic sensitivity to CT effects and is strongly dependent on the choice of kinematics. Here, we describe a possible Jefferson National Accelerator Facility (JLab) electron-scattering experiment that utilizes these kinematics and explores the potential signal for the onset of CT with enhanced sensitivity as compared to recent experiments.

Abstract:

The topics of logo design perceptions have been examined among academic scholars recently. However, elements of logo as one aspect of logo designs were rarely studied and required to be investigated. This research aimed to measure the effects of logo elements comprising type font, graphic form, and color toward brand personality perceptions, as well as to explore the relationship between business stakeholders and brand personality. In addition, logo design meaning and brand personality traits including sincerity, excitement, security, and up to date were evaluated toward logo elements. Two hundred and sixty-five samples were selected using convenience sampling from employees and residents of Thai property developers. The mix method approach was employed for the data collecting through interviewing and questionnaire survey and analyzed by Chi-square tests. The findings reveal that logo design transfers all-inclusive meaning to viewers, encompassing name, graphic, and color interpretation. Besides, there is a connection between logo elements and perception of brand personality, but in order to obtain one salient dimension of brand personality, exhibiting the whole logo was suggested rather than individual element of logo. Furthermore, brand personality was considered vital among market sharing property industry which personality of sincerity was chiefly perceived when stakeholders appreciate a logo of their real estate brands.

Abstract:

Gerbera in vitro shoots were irradiated using three types of ion beams with different line energy transfers (LETs) to investigate the effective LET and absorbed doses for mutagenesis. Furthermore, genomic mutation analyses were conducted on the obtained mutants. Survival rate analysis showed a lower lethal dose 50% (LD50) with ion beams with higher LETs. Trait/morphological mutations exhibited changes in the color and shape of petals and male sterility. Irradiation conditions with the highest growth change and trait/morphological mutation rates in each ion were C irradiation at 10 Gy, Ar irradiation at 5 Gy, and Fe irradiation at 5 Gy, with a range of absorbed dose of around LD50 to about 10 Gy lower. The highest trait/morphological mutation rate was 14.1% with Ar irradiation at 5 Gy, which was one of the criteria for ion beam irradiation of gerbera in vitro shoots. Furthermore, the genomic mutation in the flower color, petal shape, and male sterile mutants were confirmed by genotype analysis using Genotyping by Random Amplicon Sequencing-Direct technology. This is the first study to report the efficient production of gerbera mutants that could be analyzed. Our findings may lead to more efficient gerbera mutant production and analysis technology.

Abstract:

In the United States, charter school proliferation remains a top priority for neoliberal education reformers and their private sector allies. Such schools are owned and run by private operators yet receive public funding, resulting in large transfers of public assets into private hands. Co-location facilitates this process by providing charters rent-free space within existing public school buildings. The author argues that New York’s 2014 co-location reform, which guarantees co-location or rental assistance for the city’s charter schools, produces school space in ways that create new circuits for the accumulation of capital by the private sector, while at the same time putting into circulation hegemonic imaginations of the relationship of race to school space. Co-location reform enlists school space within neoliberalism’s color-blind and meritocratic racial ideology: reformers like New York Governor Andrew Cuomo “don’t care who you are” because achievement is seen as the result of hard work and good choices made in free markets, and co-location will extend educational markets to families of color who have heretofore been excluded. Using the co-location of Success Academy Charter Schools as a case, the author argues that co-location reform, animated by a “white spatial imaginary,” both obscures and exploits the racialized process of organized abandonment that underwrites neoliberal capitalism.

Abstract:

Summary: Scalp reconstruction provides a unique challenge to the reconstructive surgeon, especially in terms of matching skin color and contour. We present a case of a 67-year-old man with a chronic scalp wound requiring soft tissue coverage after major debridement and coverage of a skull defect. We chose to use a super thin deep inferior epigastric perforator (DIEP) flap to provide good skin coverage along with good contour to the scalp. The use of a super thin DIEP flap, dissected above the superficial fascial plane, is a newer technique in the realm of free tissue transfers that has shown improved outcomes in wound contour. Although the DIEP flap has been popularized for breast reconstruction, the authors believe that it has the ability to provide good soft tissue and skin coverage to other areas of the body, including in head and neck reconstruction.

Abstract:

The article studies the description of linguistic and semiotic peculiarities of sensory reflection and the interaction of precedence forms in polymodal units (Internet memes). The paper analyzes two types of synesthetic transfers: vision → smell (olfactory) and vision → hearing (auditory). On the basis of a representative sample of Russian Internet memes with olfactory and auditory semantics (450 jpeg images), the paper specifies the features of reference to precedent phenomena providing a synesthetic transfer (sensation → sensation), as well as its subtypes – a synaesthetic transfer (sensation → emotion). The description of polymodal units is based on semiotic, structural, semantic and discursive methods of analysis, and includes a comprehensive interpretation of the communicative act, taking into account situational and cultural reflection. The linguistic and semiotic peculiarities of organizing two types of synesthetic polymodal units are characterized. Internet memes with olfactory meanings feature the use of lexemes with common perceptual and olfactory semantics, interjections and the conjunction “when” to contextualize the message. The thematic categorization of auditory memes determines the use of conversational style, lexemes with perceptual semantics and graphic means of conveying sensations (the font, the color). The most frequent types of precedent forms that provide synesthesia of perceptions are analyzed. The examples demonstrate the variability of the functional meanings of precedent images. It has been established that olfactory semantics is realized through a verbal code with the description of the odor producer or the reference to an olfactory precedent phenomenon; visual precedent images actualize synesthetic transfer in olfactory memes – sensation → emotion. In terms of auditory sensation synesthesia, it was revealed that the verbal code initiates a focus on the corresponding sensation, the non-verbal one is represented by an image of a typical situation or a precedent visual image. The use of verbal and visual forms of precedence in polymodal units with synesthetic / synesthetic transfer significantly increases the role of presupposition.

Abstract:

Basalt-related sapphire had been found in Pleistocene diluvial-diluvial deposits at Hong Liem, Ham Thuan Bac district, Binh Thuan province, Vietnam. The main color of the sapphire ranged from light to extremely dark bluish green to blue, and some are blue-yellow-green, yellow-green, and seldom yellow. Their original habits were barrel-shaped crystal and hexagonal tabula; transparency to opaque; from 2 to 10 mm in diameter, sometimes up to some cm. Some sapphire samples showed a typical trapiche sapphire. Their physical and optical properties belonged to the common sapphire range, inert under the UV lamp. Their common mineral inclusions included zircon, columbite, plagioclase, hercynite, and wüstite typical of mineral inclusions found in alkaline basalt-related sapphires.Their chemical characteristic is high Fe (0.5085–1.1364 wt%), Ti (0.0109 – 0.1042 wt%), with low contents of Cr (0.0037 – 0.0085 % wt). Their color was due to the presence of single Fe3+ at 376, 378 nm, Fe3+/Fe3+ pair at 450 nm and Fe2+/Ti4+ intervalence charge transfers (IVCT) with the maximum at 571, 579 nm, raising the absorption of Fe2+/Fe3+ IVCT towards the near-infrared (maximum approximately 870 to 890 nm). Magmatic sapphire’s source was recognized not only by the Cr2O3/Ga2O3 ratio lower than 1 but also by the structural O-H group at 3309 cm-1. This sapphire was in good quality, suitable for the jewelry of relatively high economic value.

Abstract:

Al-Mg alloy strips were cast by an unequal-diameter twin-roll caster. It was found that cracks formed on the surface at grain boundaries. The grains near the surface were small in size, which likely contributed to crack formation. The use of a molten metal pouring method to increase the grain size near the surface is proposed to reduce cracks. In the previous method, molten metal is poured into a pool, which is on the lower roll surrounded by side-dam plates, a back-dam plate, and the upper roll. In this study, molten metal was directly poured onto the roll surface at a shallow angle using a launder. When the angle was smaller than 20°, cracks did not form. With the proposed method, the heat transfers between the molten metal and the roll surface decreased, as determined from the grain size and strip thickness. The cracks on the strip surface were color-checked and visually inspected.

Abstract:

Ce3+-doped and Ce3+/Mn2+ co-doped calcium carbodiimide (CaCN2) phosphors were synthesized from doped calcium carbonate and carbon nitride by a solid-state reaction at 700 °C under flowing NH3 using a very short reaction time (1 h). The samples were characterized by powder X-ray diffraction, scanning electron microscopy and their diffuse reflectance and luminescence properties were investigated. Single-doped CaCN2:Ce3+ exhibits a blue emission under near-ultraviolet activation (386 nm) corresponding to the 5d1 → 2F5/2 and 5d1 → 2F7/2 transitions of Ce3+. Maximum emission is obtained at temperatures lower than 150 K and then progressively decreases up to 387 K, with an 80% drop in the emission at room temperature. Efficient energy transfers from Ce3+ to Mn2+ via a non-radiative dipole–dipole mechanism are evidenced for the co-doped samples, leading to various colored phosphors under near-ultraviolet activation (386 nm). The emission color of the obtained phosphors can be modulated from blue to red through a shade of white depending on the sensitizer/activator ratio.

Abstract:

The preservation of Balinese carving data is a challenge in recognition of Balinese carving. Balinese carvings are a cultural heritage found in traditional buildings in Bali. The collection of Balinese carving images from public images can be a solution for preserving cultural heritage. However, the lousy quality of taking photographs, e.g., skewed shots, can affect the recognition results. Research on the Balinese carving recognition has existed but only recognizes a predetermined image. We proposed a Neural Style Geometric Transformation (NSGT) as a data augmentation technique for Balinese carvings recognition. NSGT is combining Neural Style Transfers and Geometric Transformations for a small dataset solution. This method provides variations in color, lighting, rotation, rescale, zoom, and the size of the training dataset, to improve recognition performance. We use MobileNet as a feature extractor because it has a small number of parameters, which makes it suitable to be applied on mobile devices. Eight scenarios were tested based on image styles and geometric transformations to get the best results. Based on the results, the proposed method can improve accuracy by up to 16.2%.

Abstract:

The reproductive structures of Austromegabalanus psittacus in two periods of sexual maturation were described. This organism is a simultaneous hermaphrodite, which transfers his sperm through an intromittent organ or penis. The male reproductive system consists of testes arranged in acini distributed in a tree-like structure, two vasa deferentia that come together to form the ejaculatory duct at the base of the penis. The female reproductive system consists mainly of a saccular ovary that surrounds the main body, which is internally organized into elongated acini bags containing oogonia and previtellogenic oocytes attached to the internal wall and free vitellogenic and mature oocyte within the lumen. Remarkable differences were observed in the ovaries between organisms collected in September and October. In September, they showed a yellowish ovary with two compact structures inside, called ovigerous lamellae with fertilized oocytes, embryos in different development stages and free nauplius in the body cavity, whereas in October the ovaries have a whitish in color and present a thick wall with a milky fluid inside.

Abstract:

ABSTRACT Roasting is one of the most complex coffee processing steps due to simultaneous transfers of heat and mass. During this process, beans lose mass because of fast physical and chemical changes that will set color and flavor of the commercial coffee beverage. Therefore, we aimed at assessing the kinetics of mass loss in commercially roasted coffee beans according to heating throughout the processing. For that, we used samples of 350-g Arabica coffee processed grains with water content of 0.1217 kga kg-1, in addition to a continuous roaster with firing gas. The roaster had initial temperatures of 285, 325, 345 and 380 °C, decreasing during the process up to 255, 285, 305 and 335 °C respectively. Mass loss was calculated by the difference between grain weight before and after roasting. We observed a linear variation directly dependent on roaster temperature. For each temperature during the process was obtained a constant mass loss rate, which was reported by the Arrhenius model with r2 above 0.98. In a roaster in non-isothermal conditions, the required activation energy to start the mass loss in a commercial coffee roasting index was 52.27 kJ mol -1.

Abstract:

Three species (Demotina sapensis sp. nov., Parascela filimonovi sp. nov., Colaspoides pseudofemoralis sp. nov.) are described as new to science. A key to the species of Parascela and partial key to the species of Demotina are given. Color photographs of the habitus and of both male and female genitalia are presented. New synonymies and generic transfers are proposed: Leprotes rufonotatus Pic, 1924 is resurrected as a distinct species and transferred to the genus Demotina as Demotina rufonotata (comb. and stat. nov); Parascela tuberosa (Jacoby, 1887) (comb. nov) and Parascela rugipennis (Tan, 1988) (comb. nov) are transferred from the genus Basilepta; Parascela tuberosa Tan & Wang, 1983 is a new synonym of Parascela rugipennis (Tan, 1988) because of homonymy with Parascela tuberosa (Jacoby, 1887). Clisiterella Chen, 1940 is resurrected from synonyms of Iphimoides Jacoby, 1883 and considered as its subgenus. Iphimoides (Clisitherella) suturalis (Pic, 1928) (stat.nov.) is resurrected from synonyms of I. pallidulus (Jacoby, 1889) and transferred to subgenus Clisitherella, and the following names are considered as its synonyms: Clisitherella fukienensis Tan, 1983 (syn. nov), Clisitherella suturalis Chen, 1940 (syn. nov.), Iphimoides cheni L. Medvedev, 2001 (syn. nov.).

Abstract:

Abstract A new simulator for the spread of forest root diseases, and the testing of it, is presented. It differs from earlier models in that it represents a first step to incorporate the basic processes of spread by individual root contact. It therefore has a generality that allows its use in different host–pathogen and geographic situations. It stochastically grows individual roots longitudinally outward from the stem. They are tapered, turn, and contact other roots as they grow. The simulator transfers fungus stochastically at points of contact between healthy roots and infected stump or tree roots and moves the fungus along infected tree roots stochastically. The fungus can girdle the rootcollar, move out into other roots, and eventually kill the tree. Growth of roots and fungus movement along infected roots is on an annual basis for up to 200 years. Root growth, fungus growth along roots, disease spread, and stand openings are displayed dynamically in color on the computer screen as the simulation proceeds. Estimates for numbers of infected trees and mortality are provided in tabular and graphical form. Results from the simulator were close to the field data it was tested against. FOR.

Abstract:

Different imaging conditions often result in different color reproductions. Hence, color reproductions must be calibrated when images are captured under different imaging conditions. Herein, a new color calibration method based on iterative distributed transfer (IDT) is proposed. IDT is used to preliminarily calibrate color reproductions, and the results are known as preliminary results. Because IDT may result in unnatural colors, namely false colors, the projected color components of the input image are used to suppress the false colors, and the results are the final results. To obtain the final results, a series of projection coefficients must be calculated. By minimizing the objective function, in which the preliminary results are used as the target for the final results, the projection coefficients are calculated. Simultaneously, the weight associated with the false color is incorporated into the objective function such that the final results do not depend significantly on the preliminary results when the IDT yields false colors. Meanwhile, to quantitatively evaluate the false color, a false color index is proposed herein. The proposed method can suppress false colors and offers high color-adjustment capabilities. The effectiveness of the method is verified based on evaluation indexes and the observation of experimental results.
