INNOVATIVE SYSTEM OF EDUCATION AND CARE FOR EARLY AND PRESCHOOL AGE CHILDREN

The human’s personality takes shape in preschool age. Later in school and adolescence age, a human’s personality continues to develop. However, the preschool age is the most sensitive period for forming emotional and value attitudes to cognition, interaction with the social environment, and self-development. The educational system “Education & Care” is the first complex system in preschool education; it uses modern educational technologies to develop a child’s harmonious personality and leadership potential. The system includes the Programme for early childhood and preschool education: “Education & Care”, “Monitoring the level of child’s educational development”, “Approximate daily planning”, recommendations for parents on children’s education, nutrition, and other methodical and didactic materials. The principal value of the educational system “Education & Care” is that it can be used not only by a teacher but by an adult who takes care of a child of early and preschool age and is engaged in his or her education; it is also possible to organize an effective educational process for a child even at home.

Efektifitas Validasi Bea Perolehan Hak atas Tanah dan Bangunan terhadap Ketidaksesuaian Nilai Objek Pajak dalam Akta Jual Beli dengan Harga Sebenarnya

This study aims to determine the effectiveness of the validation of Land and Building Rights Acquisition Duty (BPHTB) against tax object value discrepancies, the BPHTB validation process carried out by the Medan City Regional Revenue Service (BPPRD) and how to determine the Tax Object Principal Value (NPOP) in accordance with the actual value of the tax object. This type of research is a descriptive normative research. The effectiveness of BPHTB validation against the discrepancy in the value of tax objects is seen based on the BPHTB revenue data mentioned above, it is known that the number of targets and realization of BPHTB taxes seen from 2017 to 2019 is quite effective. The BPHTB validation process carried out by the Medan City BPPRD in general is quite satisfactory, plus currently the BPHTB SSPD validation process is carried out with an online system, so that the BPHTB SSPD validation process becomes easier and faster. How to determine the Principal Value of the Tax Object (NPOP) by determining the transaction value in the sale and purchase transaction. The use of the transaction value used as the basis for calculating BPHTB often creates problems. The difference in the transaction value agreed by the parties and stated in the deed with the transaction value used as the basis for calculating BPHTB according to BPPRD research, in this case there is uncertainty about which value is correct, so determining the NPOP in accordance with the actual value of the tax object becomes difficult. except by conducting field verification on the said BPHTB object.

Determination of perturbative QCD coupling from ALEPH $$\tau $$ decay data using pinched Borel–Laplace and Finite Energy Sum Rules

We present a determination of the perturbative QCD (pQCD) coupling using the V+A channel ALEPH $$\tau $$ τ -decay data. The determination involves the double-pinched Borel–Laplace Sum Rules and Finite Energy Sum Rules. The theoretical basis is the Operator Product Expansion (OPE) of the V+A channel Adler function in which the higher order terms of the leading-twist part originate from a model based on the known structure of the leading renormalons of this quantity. The applied evaluation methods are contour-improved perturbation theory (CIPT), fixed-order perturbation theory (FOPT), and Principal Value of the Borel resummation (PV). All the methods involve truncations in the order of the coupling. In contrast to the truncated CIPT method, the truncated FOPT and PV methods account correctly for the suppression of various renormalon contributions of the Adler function in the mentioned sum rules. The extracted value of the $${\overline{\mathrm{MS}}}$$ MS ¯ coupling is $$\alpha _s(m_{\tau }^2) = 0.3116 \pm 0.0073$$ α s ( m τ 2 ) = 0.3116 ± 0.0073 [$$\alpha _s(M_Z^2)=0.1176 \pm 0.0010$$ α s ( M Z 2 ) = 0.1176 ± 0.0010 ] for the average of the FOPT and PV methods, which we regard as our main result. On the other hand, if we include in the average also the CIPT method, the resulting values are significantly higher, $$\alpha _s(m_{\tau }^2) = 0.3194 \pm 0.0167$$ α s ( m τ 2 ) = 0.3194 ± 0.0167 [$$\alpha _s(M_Z^2)=0.1186 \pm 0.0021$$ α s ( M Z 2 ) = 0.1186 ± 0.0021 ].

Toward massless and massive event shapes in the large-β0 limit

We present results for SCET and bHQET matching coefficients and jet functions in the large-β0 limit. Our computations exactly predict all terms of the form $$ {\alpha}_s^{n+1}{n}_f^n $$ α s n + 1 n f n for any n ≥ 0, and we find full agreement with the coefficients computed in the full theory up to $$ \mathcal{O}\left({\alpha}_s^4\right) $$ O α s 4 . We obtain all-order closed expressions for the cusp and non-cusp anomalous dimensions (which turn out to be unambiguous) as well as matrix elements (with ambiguities) in this limit, which can be easily expanded to arbitrarily high powers of αs using recursive algorithms to obtain the corresponding fixed-order coefficients. Examining the poles laying on the positive real axis of the Borel-transform variable u we quantify the perturbative convergence of a series and estimate the size of non-perturbative corrections. We find a so far unknown u = 1/2 renormalon in the bHQET hard factor Hm that affects the normalization of the peak differential cross section for boosted top quark pair production. For ambiguous series the so-called Borel sum is defined with the principal value prescription. Furthermore, one can assign an ambiguity based on the arbitrariness of avoiding the poles by contour deformation into the positive or negative imaginary half-plane. Finally, we compute the relation between the pole mass and four low-scale short distance masses in the large-β0 approximation (MSR, RS and two versions of the jet mass), work out their μ- and R-evolution in this limit, and study how their implementation improves the convergence of the position-space bHQET jet function, whose three-loop coefficient in full QCD is numerically estimated.

Study on Stress-Dependent Permeability of Fracture Networks in Fractured Porous Media

In order to investigate the stress-sensitive characteristics of fracture networks under reservoir actual stress condition and its influence on the seepage in fractured porous media, we carried out permeability tests on experimental models with fracture networks under constant-volume boundary condition. In addition, a novel analytical stress-dependent permeability model of fracture networks in different directions was derived. Based on the test results and the proposed analytical model, the effects of various parameters (e.g., initial fracture aperture, fluid pressure, rock elastic modulus, effective-stress coefficient, and fracture dip) on deformation characteristics of fracture networks and the corresponding permeability tensor of fracture networks were studied. The research results show that, for a fractured porous media with a single group of fractures, the principal value of permeability is always parallel to the fracture-development direction. With increasing effective stress, the principal value of permeability decreases; however, the principal value direction remains unchanged. Moreover, for the fractured porous media with multiple sets of fractures, the principal direction of equivalent permeability will be inclined to the fractures with larger fracture aperture. Specifically, for the fractured porous media with two sets of intersecting fractures, the principal direction of equivalent permeability is parallel to the angular bisector of these two sets of intersecting fractures. Furthermore, the greater the difference of the fracture aperture change rate under effective stress, the more obvious the deviation of the permeability principal direction. The derived analytical model is of great theoretical and scientific significance to deepen the understanding of the stress-sensitive permeability of fractured reservoirs.

On A. D. Sakharov’s Hypothesis of Cosmological Transitions with Changes in the Signature of the Metric

The paper discusses possible consequences of A. D. Sakharov’s hypothesis of cosmological transitions with changes in the signature of the metric, based on the path integral approach. This hypothesis raises a number of mathematical and philosophical questions. Mathematical questions concern the definition of the path integral to include integration over spacetime regions with different signatures of the metric. One possible way to describe the changes in the signature is to admit time and space coordinates to be purely imaginary. It may look like a generalization of what we have in the case of pseudo-Riemannian manifolds with a non-trivial topology. The signature in these regions can be fixed by special gauge conditions on components of the metric tensor. The problem is what boundary conditions should be imposed on the boundaries of these regions and how they should be taken into account in the definition of the path integral. The philosophical question is what distinguishes the time coordinate among other coordinates but the sign of the corresponding principal value of the metric tensor. In particular, there is an attempt in speculating how the existence of the regions with different signature can affect the evolution of the Universe.

Moringa oleifera (horse radish tree).

M. oleifera is a small, fast-growing and short-lived tropical tree, well-known for its multi-purpose attributes, wide site adaptability and ease of establishment. Its principal value lies in its nutritional value and the use of the leaves, pods and flowers for human consumption as well as for livestock feed. The green pods are a sought-after vegetable, for example, as an essential ingredient in the making of 'sambhar', a south Indian curry and the seed oil known as 'ben-oil' is used for cooking, as a lighting fuel and for making cosmetics and soaps. The tree has attracted considerable attention in recent years with research confirming the effectiveness of using its powdered seeds as a coagulant and water purifier. The wood is of limited use. M. oleifera is grown in home gardens, as a hedging plant in and around fields and as a shade tree. It is also used for supports for vine crops such as pepper (Piper spp.).

Extended Error Expansion of Classical Midpoint Rectangle Rule for Cauchy Principal Value Integrals on an Interval

The classical composite midpoint rectangle rule for computing Cauchy principal value integrals on an interval is studied. By using a piecewise constant interpolant to approximate the density function, an extended error expansion and its corresponding superconvergence results are obtained. The superconvergence phenomenon shows that the convergence rate of the midpoint rectangle rule is higher than that of the general Riemann integral when the singular point coincides with some priori known points. Finally, several numerical examples are presented to demonstrate the accuracy and effectiveness of the theoretical analysis. This research is meaningful to improve the accuracy of the collocation method for singular integrals.

Rapid reviews: definitions and uses

This article is the first in a collaborative methodological series of narrative reviews on biostatistics and clinical epidemiology. This review aims to present rapid reviews, compare them with systematic reviews, and mention how they can be used. Rapid reviews use a methodology like systematic reviews, but through shortcuts applied, they can attain answers in less than six months and with fewer resources. Decision-makers use them in both America and Europe. There is no consensus on which shortcuts have the least impact on the reliability of conclusions, so rapid reviews are heterogeneous. Users of rapid reviews should identify these shortcuts in the methodology and be cautious when interpreting the conclusions, although they generally reach answers concordant with those obtained through a formal systematic review. The principal value of rapid reviews is to respond to health decision-makers’ needs when the context demands answers in limited time frames.
