Improved Bounds on Fourier Entropy and Min-entropy

Given a Boolean function f:{ -1,1} ^{n}→ { -1,1, define the Fourier distribution to be the distribution on subsets of [n], where each S ⊆ [n] is sampled with probability f ˆ (S) 2 . The Fourier Entropy-influence (FEI) conjecture of Friedgut and Kalai [28] seeks to relate two fundamental measures associated with the Fourier distribution: does there exist a universal constant C > 0 such that H(f ˆ2 ) ≤ C ⋅ Inf (f), where H (fˆ2) is the Shannon entropy of the Fourier distribution of f and Inf(f) is the total influence of f In this article, we present three new contributions toward the FEI conjecture: (1) Our first contribution shows that H(f ˆ2 ) ≤ 2 ⋅ aUC ⊕ (f), where aUC ⊕ (f) is the average unambiguous parity-certificate complexity of f . This improves upon several bounds shown by Chakraborty et al. [20]. We further improve this bound for unambiguous DNFs. We also discuss how our work makes Mansour's conjecture for DNFs a natural next step toward resolution of the FEI conjecture. (2) We next consider the weaker Fourier Min-entropy-influence (FMEI) conjecture posed by O'Donnell and others [50, 53], which asks if H ∞ fˆ2) ≤ C ⋅ Inf(f), where H ∞ fˆ2) is the min-entropy of the Fourier distribution. We show H ∞ (fˆ2) ≤ 2⋅C min ⊕ (f), where C min ⊕ (f) is the minimum parity-certificate complexity of f . We also show that for all ε≥0, we have H ∞ (fˆ2) ≤2 log⁡(∥f ˆ ∥1,ε/(1−ε)), where ∥f ˆ ∥1,ε is the approximate spectral norm of f . As a corollary, we verify the FMEI conjecture for the class of read- k DNFs (for constant k ). (3) Our third contribution is to better understand implications of the FEI conjecture for the structure of polynomials that 1/3-approximate a Boolean function on the Boolean cube. We pose a conjecture: no flat polynomial (whose non-zero Fourier coefficients have the same magnitude) of degree d and sparsity 2 ω(d) can 1/3-approximate a Boolean function. This conjecture is known to be true assuming FEI, and we prove the conjecture unconditionally (i.e., without assuming the FEI conjecture) for a class of polynomials. We discuss an intriguing connection between our conjecture and the constant for the Bohnenblust-Hille inequality, which has been extensively studied in functional analysis.

Belief in a Just World and Moral Personality as Mediating Roles Between Parenting Emotional Warmth and Internet Altruistic Behavior

This study explores the influence of parental emotional warmth (PEW) on college students’ Internet altruistic behavior (IAB), and the mediating roles of personal belief in a just world (PBJW) and positive moral personality traits (PMPT). A total of 893 college students were assessed using questionnaires. Results: (1) PEW, PBJW, PMPT, and IAB are positively correlated with each other; (2) PEW can directly predict the IAB of college students; and (3) PEW can indirectly predict IAB through the mediating effect of PMPT and PBJW-PMPT. PBJW and PMPT account for 22.79% of the total influence of PEW on IAB.

Analisis Pengaruh Dana Pihak Ketiga, Pembiayaan, Bancassurance Terhadap Laba Dan Dampaknya Pada Kesejahteraan Masyarakat (Studi Kasus Bank Syariah Di Indonesia)

<p>This study aims to determine how the direct influence of deposits, financing and bancassurance on the profits of Islamic banks and the welfare of society and indirect influence or through the intervening variables of profits on the welfare of society and total influence. This type of research is quantitative research. Data collection methods used are documentation methods based on data in the form of monthly financial statements for the period 2014-2018 and per capita income data that has been published. The method of data analysis in this study is by using the path analysis method. The results of the study show that financing significantly affects earnings while third party funds and bancassurance do not directly affect earnings. Deposits and profits of Islamic banks significantly influence directly on public welfare and bancassurance negatively influences people's welfare while financing does not. Financing indirectly significantly influences welfare through profit variables, whereas DPK and bancassurance do not. Business activities of Islamic banks have a role in addition to achieving company profits, also have a positive impact on the welfare of the Indonesian people. Funding and third party funds that generate profits are a determining factor for improving community welfare rather than bancassurance sales.</p>

Top-down identification of keystone species in the microbiome

Keystone species in ecological communities are native species that play an especially important role in the stability of their ecosystem and can also be potentially used as its main drivers. However, we still lack an effective framework for identifying these species from the available metagenomic data without the notoriously difficult step of reconstructing the detailed network of inter-specific interactions. Here we propose a top-down identification framework, which detects keystones by their total influence on the rest of the species. Our method does not assume pairwise interactions or any specific underlying dynamics and is appropriate to both perturbation experiments and metagenomic cross-sectional surveys. When applied to real metagenomic data of the human gastrointestinal microbiome, we detect a set of candidate keystones and find that they are often part of a keystone module -- multiple candidate keystones species with correlated occurrence. The keystones analysis of single-time-point cross-sectional data is also later verified by evaluation of two-time-points longitudinal sampling. Our framework represents a necessary advancement towards the reliable identification of these key players of complex, real-world microbial communities.

ESTIMATION OF ACCURACY OF COORDINATED SMALL DIAMETER HOLES WITH CUTTING TOOL DIRECTION

The dimensional analysis of the initial parameters of the coordinated dimensions of the holes is presented. Issues related to the assessment of the accuracy of the location of the surfaces of deep holes are considered. The influence of various technological factors on the magnitude of scattering of coordinated dimensions is studied. Experimental studies using experimental design methodology, which was used for sample preparations 45 steel, cast iron SCH15, aluminum alloys. Factors such as the cutting angle, the hardness of the workpiece, the cutting force and their effect on the diameter of the impression and its depth were studied. As a result of the experiments, a slight effect of the drilling force on the diameter and depth of the impression was found. However, it was found that the angle of the core leads to a directly proportional increase in the diameter of the imprint and inversely affects its depth. The hardness of the material has a more significant effect on the diameter of the imprint than on its depth. The total influence of controlled factors significantly affects the diameter of the imprint. Minimum core drilling angles are proposed for some materials. A mathematical model of the accuracy of machining coordinated holes is proposed on the basis of estimating the coefficients of the regression equation and finding the required mathematical models of the scattering fields of dimensions and deviations. As factors that vary during the drilling of coordinated holes, were taken: the length of the conductor sleeve, the departure of the tool, the hardness of the workpiece, the diameter of the tool. It is found that with increasing tool diameter and guide sleeve length decreases the amount of dimensional scattering from the base and positional deviations, and increasing tool departure and improving the physical and mechanical properties of the workpiece increase the size of the size scattering field from the base and positional deviation. An additional factor was introduced: the gap in the combination between the cutting tool and the conductor sleeve and obtained mathematical dependences of the influence of factors on dimensional accuracy when machining deep holes with the direction of the cutting tool. It is shown that the introduction of an additional factor - the gap, did not change the essence of the process of errors on small aggregate machines, and the change in diameters does not lead to a significant increase in scattering fields.

Comparative Analysis of Meat Bone Meal and Meat Bone Combustion Using the Life Cycle Assessment Method

LCA analysis with 16 impact categories was used for the comparison of two developed combustion technologies: Scenario I—the combustion of meat bone meal produced from all types of meat waste; Scenario II—the combustion of meat bones from the production of meat products. The key hotspots determined were electricity and natural gas consumption, covering as much as 98.2% of the total influence on the environment in Scenario I and 99.3% in Scenario II. Without taking into account the environmental burdens avoided, the LCA analysis showed that Scenario I was assessed to have 71.2% less environmental impact. The avoided burdens approach changed the relationship between the two scenarios. The absolute value score for the overall environmental impact shows that Scenario II can be more environmentally beneficial than Scenario I; however, Scenario I allowed the elimination of all types of Polish meat waste, and Scenario II could only be carried out in meat production units for the elimination of meat bone waste and by-products from meat processing (i.e., 23% of the total meat waste produced in Poland).
