description: The regularity of the distribution of chlorophylls content in a series of 30 cultivated plants and 75 steppe grasses was studied. The increased content of chlorophyll and magnesium in vegetables and grains compared with greens and steppe grasses is associated with more complex genetics of metabolism, which has stages of flowering and fruiting. The chlorophyll content increases with the use of LED phytoirradiators with an emission band coinciding with the first absorption band of chlorophyll. Industrial electromagnetic fields can affect the biosynthesis of pigments in deciduous trees, but cultivated herbaceous plants are not sensitive to them.

description: The purpose of this study was first to determine the educational orientation of a sample of Education Services Officers (ESOs), Education Services Specialists (ESSs), and Guidance Counselors (GCs); second, to determine the relationship of the independent variables of age, sex, years in the Army Continuing Education System (ACES), and formal education to the dependent variable, educational orientation, measured by Hadley's (1979) Educational Orientation Questionnaire (EOQ), of each personnel group; and finally, to determine the collective strength of these variables in predicting educational orientation. The final sample consisted of 298 volunteer subjects of 510 personnel surveyed (58 percent)--113 Education Services Officers, 90 Education Services Specialists, and 95 Guidance Counselors randomly selected from personnel rosters maintained by Headquarters, Department of Army, ACES Office. Descriptive statistics and data from a one-way analysis of variance were used to determine the educational orientation of ACES personnel. For ESOs, there were no significant positive correlations between the independent variables and dependent variable. The findings for ESSs suggested a positive but nonsignificant relationship between gender and subdimensions 3, 4, 5 and total EOQ score. The findings for Guidance Counselors suggested a weak positive relationship with level of education and subdimensions 1, 2, 3, 4 and total EOQ score. A relationship also emerged between subdimension 4, and gender (R$\sp2$ =.15). Multiple regression analysis was used to determine the strength of the independent variables in predicting EOQ scores. None of the independent variables proved to be important predictors of EOQ score for ESOs. A positive but nonsignificant relationship was suggested for the variable of sex for ESSs (females were more andragogical than males). A positive but nonsignificant relationship was suggested with both sex and education for GCs. The strong pedagogical orientation of this sample of military educators suggests that they maintain a traditional view of both the learning process and the teacher-student relationship. The institutional climate of the military community may be a factor contributing to their orientation. Caution should be exercised concerning both the gender and education findings in this study. In both cases, the results may be masked by skewed independent variables which lessen the probability that statistically significant relationships will be found.

description: In this communication a new algorithm is proposed to produce surrogates for pseudoperiodic time series. By imposing a few constraints on the noise components of pseudoperiodic data sets, we devise an effective method to generate surrogates. Unlike other algorithms, this method properly copes with pseudoperiodic orbits contaminated with linear colored observational noise. We will demonstrate the ability of this algorithm to distinguish chaotic orbits from pseudoperiodic orbits through simulation data sets from theRössler system. As an example of application of this algorithm, we will also employ it to investigate a human electrocardiogram (ECG) record.

description: We discuss a new class of brane models (extending both p-brane and Dp-brane cases) where the brane tension appears as an additional dynamical degree of freedom instead of being put in by hand as an ad hoc dimensionfull scale. Consistency of dynamics naturally involves the appearence of additional higher-rank antisymmetric tensor gauge fields on the world-volume which can couple to charged lower-dimensional branes living on the original Dp-brane world-volume. The dynamical tension has the physical meaning of electric-type field strength of the additional higher-rank world-volume gauge fields. It obeys Maxwell (or Yang-Mills) equations of motion (in the string case p=1) or their higher-rank gauge theory analogues (in the Dp-brane case). This in particular triggers a simple classical mechanism of ("color") charge confinement.

description: We show that solitonic solutions of the classical string action on the AdS_5 x S^5 background that carry charges (spins) of the Cartan subalgebra of the global symmetry group can be classified in terms of periodic solutions of the Neumann integrable system. We derive equations which determine the energy of these solitons as a function of spins. In the limit of large spins J, the first subleading 1/J coefficient in the expansion of the string energy is expected to be non-renormalised to all orders in the inverse string tension expansion and thus can be directly compared to the 1-loop anomalous dimensions of the corresponding composite operators in N=4 super YM theory. We obtain a closed system of equations that determines this subleading coefficient and, therefore, the 1-loop anomalous dimensions of the dual SYM operators. We expect that an equivalent system of equations should follow from the thermodynamic limit of the algebraic Bethe ansatz for the SO(6) spin chain derived from SYM theory. We also identify a particular string solution whose classical energy exactly reproduces the one-loop anomalous dimension of a certain set of SYM operators with two independent R charges J_1, J_2.

description: The aim of this research is to detect small objects with low resolution and noise. The existing real time object detection algorithm is based on the deep neural network of convolution need to perform multilevel convolution and pooling operations on the entire image to extract a deep semantic characteristic of the image. The detection models perform better for large objects. The features of existing models do not fully represent the essential features of small objects after repeated convolution operations. We have introduced a novel real time detection algorithm which employs upsampling and skip connection to extract multiscale features at different convolution levels in a learning task resulting a remarkable performance in detecting small objects. The detection precision of the model is shown to be higher and faster than that of the state-of-the-art models.

Struggle for predominance: Evolution and consolidation of nuclear forces in the Strategic Air Command, 1945-1955
Creators: name: Borgiasz, William Stephen
Publisher: name: American University
Year: 2023

description: This work analyzes the evolution of the U.S. strategic air forces from 1945 to 1955. In World War II, U.S. air power demonstrated its superior effectiveness as a weapon. Yet no military arm can stop improving and survive. The nuclear age changed the characteristics of war. No longer would general wars become lengthy engagements involving massive armies. The threat of atomic bombing now threatened the vital center of a nation. Under the new horror of a nuclear Pearl Harbor, the country that prepared in advance and mastered the technology of the nuclear bomb might survive. As commander of the Strategic Air Command from 1948 through 1955, Curtis E. LeMay shaped U.S. strategic forces to survive in the new world. He insisted that the Air Force have access to atomic energy information for strategic planning. In the Cold War, the United States had very few bombers capable of delivering an atomic attack against its probable enemy the Soviet Union. LeMay worked to obtain the best planes that industry could produce. He also struggled to find, promote, and retain the most qualified pilots and support personnel in the air force. To keep the planes flying, LeMay relied heavily on his wartime experience. He revitalized maintenance procedures and trained his combat crews endlessly to perfect their bombing skills. To this end LeMay emphasized radar bombing and better intelligence on targets in the Soviet Union. This work has six chapters. The first describes the evolution of Air Force strategic planning from 1945 to 1953. The second chapter explains the New Look emphasis on strategic forces. The third chapter explains the importance of personnel to the SAC mission and how LeMay addressed the problem. The fourth chapter examines the development of specialized maintenance in SAC. The fifth chapter traces the transition from the B-47 to the B-52. The sixth chapter explores the importance of intelligence and targeting.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the moduli space of the boundary conformal field theories describing an unstable D-brane of type II string theory compactified on a circle of critical radius. This moduli space has two branches, -- a three dimensional branch S^3/Z_2 and a two dimensional branch described by a square torus T^2. These two branches are joined along a circle. We compare this with the moduli space of classical solutions of tachyon effective field theory compactified on a circle of critical radius. This moduli space has a very similar structure to that of the boundary conformal field theory with the only difference that the S^3 of the S^3/Z_2 component becomes a deformed S^3. This provides one more indication that the tachyon effective field theory captures qualitatively the dynamics of the tachyon on an unstable D-brane.

description: We recently studied two large but disjoint classes of twisted open WZW strings: the open-string sectors of the WZW orientation orbifolds and the so-called basic class of twisted open WZW strings. In this paper, we discuss {\it all T-dualizations} of the basic class to construct the {\it general} twisted open WZW string -- which includes the disjoint classes above as special cases. For the general case, we give the {\it branes} and {\it twisted non-commutative geometry} at the classical level and the {\it twisted open-string KZ equations} at the operator level. Many examples of the general construction are discussed, including in particular the simple case of twisted free-bosonic open strings. We also revisit the open-string sectors of the general WZW orientation orbifold in further detail. For completeness, we finally review the {\it general twisted boundary state equation} which provides a complementary description of the general twisted open WZW string.

description: In order to improve the intensive cultivation and management technology of Olea europaea in the high density orchard, through an analysis on the 3a growth, yield and orchard construction cost for different varieties and different densities in Gansu Wudu ordinary O.europaea orchard and close O. europaea planting orchard, the appropriate conditions, varieties and density for intensive orchard construction were initially selected. The results showed that the tree height growth in the ordinary orchard was 119% of the tree height growth in the high density orchard, while the ground diameter growth in the ordinary orchard was 112% of the ground diameter growth in the high density orchard, but the yield in the ordinary orchard was only 62% of the yield in the high density orchard; of the 8 new varieties introduced from Spain, "Arbequina", "Arbosana" and "Koroneiki" were the appropriate varieties for the intensive orchard construction; the ratio of the ordinary orchard construction cost to the high density orchard construction cost was 1: 6.24. Under high water and fertilizer conditions, the ratio of the ordinary orchard yield to the high density orchard yield was 1: 4.481. Therefore, in the flat land area, using the appropriate intensive cultivars, and integrating the high-tech achievements and advanced management tools, can increase output per unit area, and greatly save manpower and land costs, to achieve the purpose of high quality, high yield and stable production. In the production practice, it is necessary to vigorously promote the intensive cultivation technology of O. europaea.
Poverty among single parent families: A "Basic Needs Budget" approach
Creators: name: Renwick, Trudi Jane
Publisher: name: American University
Year: 2023

description: In 1989 the official poverty rate (as calculated by the Census Bureau) for single parent families was almost five times greater than the poverty rate for married couple families. Half of all poor families in the United States today are headed by a single parent. As dismal as these statistics appear, they in fact understate the problem because they are derived using an outdated approach to measuring poverty. This paper proposes a new approach to setting the poverty line and estimating poverty rates for single parent families using a "Basic Needs Budget" which calculates on an item-by-item basis how much single parent families need to make ends meet. In 1989, the before-tax income need to support the Basic Needs Budget for a central city family consisting of a single parent employed outside the home and two preschool children was almost $18,000, almost twice the official poverty threshold. Unlike the official thresholds, the Basic Needs Budgets make allowances for the additional resource needs of families in which the single parent is employed outside the home--most importantly the cost of child care services. The budgets are adjusted to reflect the reduced income needs of families who receive in kind benefits--i.e., food stamps, school lunches, public housing, energy assistance, Medicaid, Title XX child care and employer-provided group health insurance. When these thresholds are used to recalculate the major poverty statistics, the poverty rate of single parent families increases by 18 percent from 44 percent to 51 percent. The poverty rate of AFDC recipients declines slightly (due to the importance of noncash benefits for this subgroup) while the poverty rate of full time workers triples. The Basic Needs Budgets show that unless subsidized child care is available, most women cannot earn enough to make going off welfare rational choice.

description: We look at the interior operator reconstruction from the point of view of Petz map and study its complexity. We show that Petz maps can be written as precursors under the condition of perfect recovery. When we have the entire boundary system its complexity is related to the volume / action of the wormhole from the bulk operator to the boundary. When we only have access to part of the system, Python's lunch appears and its restricted complexity depends exponentially on the size of the subsystem one loses access to.

description: Statistical hypothesis testing is a central method for the judgement of empirical findings in the medical, social and natural sciences. In recent years, the ongoing problems with null hypothesis significance testing and p-values have shown that the underlying paradigm for quantifying statistical evidence about a research hypothesis is highly problematic, and the situation has been termed a replication crisis. In this thesis, the evolution of statistical hypothesis testing is reconstructed, and it is shown that various of the recently observed problems with the reproducibility of research can be attributed to the underlying statistical theory of widely used inferential statistical methods. In the first part, the development of an inconsistent hybrid approach to statistical hypothesis testing which emerged out of Fisher’s theory of significance tests, p-values and the Neyman-Pearson theory is analyzed. In part two, the evolution of Bayesian approaches to hypothesis testing is detailed with a focus on the Bayes factor. Part three discusses the development of modern Markov-Chain-Monte-Carlo algorithms and their impact on Bayesian hypothesis testing. Part four then provides an axiomatic analysis of the concept of statistical evidence in the context of statistical hypothesis testing and it is shown that various substantial problems which were observed in the replication crisis can be attributed to purely axiomatic inconsistencies and conflicts with the likelihood principle. Based on the axiomatic analysis, it is shown that robust Bayesian methods, in particular robust Bayesian hypothesis tests provide a solution to some substantial problems with the reproducibility of research. Bayesian statistical solutions to the replication crisis are provided in the fifth part with a focus on widely used Bayesian statistical models in the biomedical sciences. New results demonstrate that the implicit error control of Bayesian hypothesis tests is comparable to frequentist tests based on p-values, and that a variety of Bayesian evidence measures attains reasonable type I error control and power in practice. Also, a shift towards the Hodges-Lehmann paradigm which advocates testing small interval instead of point null hypotheses is explored, and new theoretical results show that such a shift may be an appealing additional step towards increasing the reproducibility of science which has not received enough attention in the discussion about the validity of statistical hypotheses and the reproducibility of scientific research.

description: Fraudulent claim detection is one of the greatest challenges the insurance industry faces. Alibaba's return-freight insurance, providing return-shipping postage compensations over product return on the e-commerce platform, receives thousands of potentially fraudulent claims every day. Such deliberate abuse of the insurance policy could lead to heavy financial losses. In order to detect and prevent fraudulent insurance claims, we developed a novel data-driven procedure to identify groups of organized fraudsters, one of the major contributions to financial losses, by learning network information. In this paper, we introduce a device-sharing network among claimants, followed by developing an automated solution for fraud detection based on graph learning algorithms, to separate fraudsters from regular customers and uncover groups of organized fraudsters. This solution applied at Alibaba achieves more than 80% precision while covering 44% more suspicious accounts compared with a previously deployed rule-based classifier after human expert investigations. Our approach can easily and effectively generalizes to other types of insurance.

We find several new supersymmetric oblique and curved D-branes. The supersymmetries preserved by various configurations of these D-branes including their intersections are also identified. In particular, we show that $D_+$-branes of type (+,-,n,n) for n=1,2,3,4 preserve 4 dynamical supersymmetries by introducing gauge field excitations and newly discovered oblique D5- and D7-branes also preserve four or two dynamical supersymmetries with gauge field condensates. Furthermore we find new curved D-branes preserving four dynamical supersymmetries.

description: To evaluate main traits of sugarcane germplasm resources with high sucrose content and provide theoretical foundation for parental selection of sugarcane breeding, taking ROC22 as the control, the one-year plant and ratoon were planted in the field experiment with the collected 42 samples, and evaluation and survey were carried out on the agronomic traits. The results indicated that the effective stems of 35 strains including GT07-104, GT08-743, and GT04-1029 were higher than that of ROC22, reaching the significant difference and reached extremely significant difference with GT08-1533. The average Brix of new ratoon of GT02-901, GT07-110 and GT09-53 was the highest in October, close to 21.89%, 21.40% and 21.24% respectively, which was 17.3% higher than that of the control R22. The Brix weight of 39 samples including GT04-1001, GT08-898 and GT04-1029 was higher than that of the control group, but the Brix weight of GT02-901, GT08-221, GT07-548 and GT02-237 was lower. In conclusion, in 42 sugarcane germplasm samples with high sucrose, GT07-104, GT04-1029, GT04-1001, GT07-110, GT07-135, GT08-743 and GT07-5A have more effective stems, stronger ratoon ability, and excellent comprehensive early-maturing traits. In view of characteristics of these samples, these germplasm resources can be used as parental crossing and combination ratio, to select target sugarcane varieties.

description: The effect of unitary noise on the performance of Grover's quantum search algorithm is studied. This type of noise may result from tiny fluctuations and drift in the parameters of the (quantum) components performing the computation. The resulting operations are still unitary, but not precisely those assumed in the design of the algorithm. Here we focus on the effect of such noise in the Hadamard gate $W$, which is an essential component in each iteration of the quantum search process. To this end $W$ is replaced by a noisy Hadamard gate $U$. The parameters of $U$ at each iteration are taken from an arbitrary probability distribution (e.g. Gaussian distribution) and are characterized by their statistical moments around the parameters of $W$. For simplicity we assume that the noise is unbiased and isotropic, namely all noise variables in the parametrization we use have zero average and the same standard deviation $ε$. The noise terms at different calls to $U$ are assumed to be uncorrelated. For a search space of size $N=2^n$ (where $n$ is the number of qubits used to span this space) it is found that as long as $ε< O(n^{-{1/2}} N^{-{1/4}})$, the algorithm maintains significant efficiency, while above this noise level its operation is hampered completely. It is also found that below this noise threshold, when the search fails, it is likely to provide a state that differs from the marked state by only a few bits. This feature can be used to search for the marked state by a classical post-processing, even if the quantum search has failed, thus improving the success rate of the search process.
Electrostatic and metal interaction chromatography of sulfonamides
Creators: name: Del Grosso, Alfred Vincent
Publisher: name: American University
Year: 2023

description: A diethylenetriamine functional stationary phase, capable of complexing transition metal ions, was developed and evaluated for use in HPLC separations. Synthesis involved evaporation of a trimethoxysilylpropyl-monomer. Surface coverages of 3.0 $\mu$moles/m$\sp2$ were obtained on 100 angstrom, 550 m$\sp2$/g silica. Analytical columns were loaded with Cu(II), Ni(II) and Zn(II) by the frontal elution process; breakthrough volumes corresponded well with metal uptake determined by atomic absorption spectrophotometry. Buffered aqueous-organic mobile phases were used for separations of sulfonamide antimicrobials that included sulfa-diazine, sulfa-thiazole, sulfa-merazine and sulfa-pyridine. An empirical retention expression was developed that related chromatographic retention to (a) electrostatic interaction of the acidic sulfonamide function with the cationic stationary phase, (b) secondary metal-ligand complexations involving the heterocyclic aromatic substituents of the solutes and (c) solubilization of the relatively hydrophobic solutes in the mobile phase. Analyte retention was inversely proportional to concentrations of organic modifier and buffer. Eluent pH was generally directly proportional to solute retention. An eluent of pH 7.2 phosphate buffer and 50% methanol was effective in minimizing electrostatic interactions while allowing retention based on metal-ligand interactions.

A comparative study of adjustment difficulties of American male and female students in Israeli institutions of higher learning

description: The study addressed four research questions concerning the adjustment difficulties experienced by Americans who were studying in Israeli colleges, universities, and yeshivoth. Furthermore, four hypotheses were tested which dealt with gender differences in the adjustment process. In November and December of 1989, 671 American undergraduates in Israeli institutions were surveyed to determine how difficult it was for them to make fifty-three specific school-related adjustments. Each participant completed the Study Abroad Adjustment Inventory (SAAI), which was created by the writer specifically for this research. The SAAI categorized the adjustment difficulties into four general areas: Hebrew language, academic matters, personal situations, and living arrangements. It utilized four extent-of-difficulty response alternatives: 1.00 = none, 2.00 = not serious, 3.00 = serious, 4.00 = very serious, to assess student difficulty with each adjustment. The four hypotheses were tested by using the t test statistic. Significance was set at the.05 level. Study findings indicated that the sample of students in this research reported the most serious (X = 2.87) and most frequent adjustment difficulties in the "living arrangements" problem area among the four problem areas considered. Overall, the mean student extent-of-difficulty response to each of the set of fifty-three adjustments presented on the SAAI did not exceed 3.00 (serious). A significant disparity in adjustment difficulty was found between males and females for eighteen of the fifty-three adjustments. Males had more difficulty than females adjusting to matters in the "personal situations" problem area. Female students encountered significantly more difficulties than males adjusting to problems in the "academic matters" area. No significant gender difference was found regarding the "living arrangements" or "Hebrew language" problem areas. Although more than one third of study subjects reported that their mastery of the Hebrew language before starting to study in Israel was "none" to "poor," their adjustment difficulty with the "Hebrew language" problem area was less than "not serious" (X = 1.78). One study conclusion is that competency in Hebrew is not essential for a successful adjustment by American students, similar to those in this sample, to study in Israeli colleges, universities, and yeshivoth. The findings are interpreted for their meaning to directors of foreign student programs in Israeli post-secondary institutions and to advisors in the United States of American students planning to study abroad.

description: Atomic absorption spectrophotometry, sulfuric acid and potassium dichromate oxidation method and ultraviolet spectrophotometry, were used to determine mineral elements, fiber, the content of chlorogenic acid and flavones in leaves of 24 Helianthus tuberosus Linn. resources, and the characteristics of the leaf introduced from abroad were evaluated. The results showed that the highest water content of 22 species was F12 (27.58%), and the lowest was F16 (19.02%). The difference in mean water content between the species from Denmark and France was small, but it was lower than that of Qingyu 3 and Qingyu 4. There were 3 orbicular leaves, 1 long oval-shaped leaf and 18 oval leaves. The highest K content in the leaves was F19 (30.62 mg/g), which was 2.5 times than Qingyu 3. The highest Mg content was D8 (14.17 mg/g). The Fe content had little difference, ranging from 0.09 mg•g−1 to 0.19 mg/g. The highest Ca content was D8 (26.87 mg/g). The highest level of chlorogenic acid and flavones was F7, 2.55% and 1.24 g/100 g respectively. The highest fiber content was F9 (16.7%), and the lowest was F19 (7.36%). Through the analysis of the main component and the clustering analysis, when the genetic distance was 0.65, the 24 resources can be divided into three major categories. The first category of leaves were mainly oval and orbicular; the second category of leaves were long oval-shaped; the third category of leaves were oval. There was a difference between the various indexes in the leaf of different kinds of Helianthus tuberosus Linn. resources. Finally, F19, D8, F9, F7, D14 and D11, 6 specific species (F19, D8, F9, F7, D14 and D11) were screened out for further studies in the future.
