The Absence of “Perfect Induction”in the Science

The present paper is finalized to show that the Science, even if considered in its two different Phenomenological Approaches at present known, is unable to assert that: “Thinks are like that”. This is because both the two Scientific Approaches previously mentioned have not the property of “the perfect induction”. Consequently, although they can even reach an experimental confirmation of the theoretical results, and thus a “valid description” of the various phenomena of the surrounding world, such a description has not an “absolute value”. In fact, it always and only has an “operative validity”, that is, it exclusively and solely refers to an “experimental point of view”. This means that such an “operative validity” cannot represent the basis for a logical process characterized by a “perfect induction”. In addition, the Traditional Scientific Approach is also characterized by “Insoluble” Problems, “Intractable Problems”, Problems with “drifts”, which could generally be termed as “side effects”. On the other hand, the same com-possible Scientific Approach based on the Emerging Quality of Self-Organizing Systems, also presents its “Emerging Exits”. Consequently, none of the two mentioned scientific Approaches has the “gift” of “the perfect induction”. However, there are significant differences between the two. Differences that may “suggest” the most appropriate choice among them for an “operative point of view”. This conclusion will be com-proved by considering, with particular reference, both the “side effects”, which are related to the Traditional Approach and, on the other hand, the “Emerging Exits”, which specifically pertain to the new Scientific Approach based on the Emerging Quality of Self-Organizing Systems.

Optical Properties and Structural Perfection of Chicago Sky Blue 6B-doped KDP Crystals

KDP crystals doped with Chicago Sky Blue 6B（CSB-6B） were grown by traditional lowering temperature method.The optical properties and structural perfection of KDP crystals were investigated by transmittance spectra and high-resolution X-ray diffraction,respectively.The results indicate that CSB-6B tends to be incorporated into the pyramidal sector of KDP crystals（PyS-KDP） and lead to inclusions parallel to（101） face.Additionally,the transmittance of as-grown KDP crystals decreases as the amount of CSB-6B increases. Moreover,the rocking curves of PyS-KDP suggest that CSB-6B can deteriorate the structural perfection of PyS-KDP.

Predicting adolescent perfectionism: The role of socio-demographic traits, personal relationships, and media

BACKGROUND The present study investigated perfectionism from the bioecological model perspective as a multidimensional construct manifested in forms of excessively high personal standards,exaggerated worries about personal mistakes,doubt in one’s performance,oversized order and organization emphasis,and the importance of parental valuations and expectations.AIM To investigate the relation between perfectionism;the quality of family,peer,and college relationships;and media usage and content interests.METHODS The research was implemented in 2020 with 203 students(134 female,66%)aged 18-25 years,enrolled at the University of Osijek in Croatia.The questionnaire had five parts:A)sociodemographic data;B)the Multidimensional Perfectionism Scale;C)the“general life satisfaction”and“current situational life satisfaction”scale;D)family,peer,and college relationships quality scale;and E)media usage and content interests scale.All of the implemented instruments showed satisfactory reliability.A hierarchical regression analysis was implemented with the aim of establishing significant perfectionism predictors.RESULTS Age and gender were significant predictors of perfectionism.Participants with lower family relationship quality reported higher parental expectations and complaining as well as significantly higher doubts in personal performance and concern about mistakes.Similarly,a lower peer relationship quality predicted doubts in personal performance and stronger concerns about mistakes.The quality of college relationships positively predicted higher perfectionist personal standards and organization.General life satisfaction predicted higher concerns about mistakes,while current situational life satisfaction predicted higher levels of perfectionist organization.Media usage intensity had no significant effect.Adolescent interest in information-educational media predicted higher personal standards as well as concern about mistakes and organization.Higher interests in entertainment media content predicted more concern about mistakes,while interest in negative media content negatively predicted organization in adolescents.CONCLUSION Sociodemographic traits,relationships with family,peers and colleagues,as well as life satisfaction and media content interests represent significant adolescent perfectionism predictors,explaining 14%-28%of individual perfectionism dimensions.

Cross-layer design of combining AMC with HARQ in cooperative relay system with perfect and imperfect CSI

A cross-layer design which combines adaptive modulation and coding (AMC) at the physical layer with a hybrid automatic repeat request (HARQ) protocol at the data link layer (LL) is presented, in cooperative relay system over Nakagami-m fading channels with perfect and imperfect channel state information (CSI). In order to maximize spectral efficiency (SE) under delay and packet error rate (PER) performance constraints, a state transition model and an optimization framework with perfect CSI are presented. Then the framework is extended to cooperative relay system with imperfect CSI. The numerical results show that the scheme can achieve maximum SE while satisfying transmitting delay requirements. Compared with the imperfect CSI, the average PER with perfect CSI is much lower and the spectral efficiency is much higher.

Application of Perfect Difference Codes in Wireless Infrared Systems

In this paper, we apply the perfect difference codes in wireless infrared systems considering the diffuse indoor optical wireless configuration. The bit error rate performance of the uplink wireless infrared system using Gaussian approximations is analyzed taking into account the effects of multiple-access interference, the ambient light noise, and the dark current. The proposed system also uses the compact encoder and decoder architecture resulting in a low cost system.

The Stages of the Soul Through the Path of Perfection:The Journey of the Servants to the Place of Return(Seyr al-‘Ibād ilāal-Ma‘ād)

The Journey of the Servants to the Place of Return(Seyr al-‘Ibād ilāal-Ma‘ād)is an allegory mathnavi that suggests a man’s spiritual purification through a deeper understanding of creation,the influence of the planets,and the four elements on his thoughts and behaviors.Their effect will change a man’s life after his death if he does not control them.By taming the negative traits,he may enjoy the bliss of paradise if he does not control them,and may enter into the fire of hell.This mystical/literary work offers practical methods that may eliminate negative traits in an individual’s soul if he practices them.The poet emphasizes the necessity of following a master who guides the pupil through a spiritual journey to achieve perfection and become one with the Creator.

Analysis on the Reform Path of the Hierarchical Treatment System for Juvenile Delinquents in China

Although it has stipulated a treatment system for juvenile delinquents in the existing law of China,the related provisions are scattered throughout different legal norms and need to be integrated and perfected.The existing treatment of juvenile delinquents,including administrative treatment and judicial treatment,mainly faces the following problems:(a)The treatment measures are too rough and simple to effectively combine punishment with leniency effectively;(b)The hierarchical treatment measures are not perfect enough procedurally;(c)The non-criminal treatment measures do not produce the desired effect.Based on a good understanding of the basic connotations of the hierarchical treatment system for juvenile delinquents,it is necessary to take the following steps:(a)Treat the juvenile delinquents in appropriate ways according to the subject,specific content,and severity of juvenile delinquencies;(b)Take highly-targeted and flexible treatment measures at different stages of criminal proceedings,namely,take criminal coercive measures against juvenile delinquents in a prudent manner and impose criminal punishments against them in a relatively lenient manner,to better help them return to society.

High-temperature annealing of(201)β-Ga_(2)O_(3) substrates for reducing structural defects after diamond sawing

A commercial epi-ready(201)β-Ga_(2)O_(3) wafer was investigated upon diamond sawing into pieces measuring 2.5×3 mm^(2).The defect structure and crystallinity in the cut samples has been studied by X-ray diffraction and a selective wet etching technique.The density of defects was estimated from the average value of etch pits calculated,including near-edge regions,and was obtained close to 109 cm^(-2).Blocks with lattice orientation deviated by angles of 1-3 arcmin,as well as non-stoichiometric fractions with a relative strain about(1.0-1.5)×10^(-4)in the[201]direction,were found.Crystal perfection was shown to decrease significantly towards the cutting lines of the samples.To reduce the number of structural defects and increase the crystal perfection of the samples via increasing defect motion mobility,the thermal annealing was employed.Polygonization and formation of a mosaic structure coupled with dislocation wall appearance upon 3 h of annealing at 1100℃ was observed.The fractions characterized by non-stoichiometry phases and the block deviation disappeared.The annealing for 11 h improved the homogeneity and perfection in the crystals.The average density of the etch pits dropped down significantly to 8×10^(6) cm^(-2).

Generation of microwave photon perfect W states of three coupled superconducting resonators

We propose an efficient method for the generation of perfect W states on three microwave superconducting resonators,of which the two nearest neighbors are coupled by a symmetric direct current superconducting quantum interference device(dc-SQUID).With suitable external magnetic fluxes applied to the dc-SQUID symmetry loops,on-chip tunable interactions between neighboring resonators can be realized,and different perfect W states can be deterministically created on-demand in one step.Numerical simulations show that high-fidelity target states can be generated and our scheme is robust against imperfect parameter tuning and environment-induced decoherence.The present work may have potential applications for implementing quantum computation and quantum information processing based on microwave photons.

Finite-difference modeling of Maxwell viscoelastic media developed from perfectly matched layer

In numerical simulation of wave propagation,both viscoelastic materials and perfectly matched layers(PMLs)attenuate waves.The wave equations for both the viscoelastic model and the PML contain convolution operators.However,convolution operator is intractable in finite-difference time-domain(FDTD)method.A great deal of progress has been made in using time stepping instead of convolution in FDTD.To incorporate PML into viscoelastic media,more memory variables need to be introduced,which increases the code complexity and computation costs.By modifying the nonsplitting PML formulation,I propose a viscoelastic model,which can be used as a viscoelastic material and/or a PML just by adjusting the parameters.The proposed viscoelastic model is essentially equivalent to a Maxwell model.Compared with existing PML methods,the proposed method requires less memory and its implementation in existing finite-difference codes is much easier.The attenuation and phase velocity of P-and S-waves are frequency independent in the viscoelastic model if the related quality factors(Q)are greater than 10.The numerical examples show that the method is stable for materials with high absorption(Q=1),and for heterogeneous media with large contrast of acoustic impedance and large contrast of viscosity.

Reduced Imaging Time and Improved Image Quality of 3D Isotropic T2-Weighted Magnetic Resonance Imaging with Compressed Sensing for the Female Pelvis

This study is to compare three-dimensional(3D)isotropic T2-weighted magnetic resonance imaging(MRI)with compressed sensing-sampling perfection with application optimized contrast(CS-SPACE)and the conventional image(3D-SPACE)sequence in terms of image quality,estimated signal-to-noise ratio(SNR),relative contrast-to-noise ratio(CNR),and the lesions’conspicuous of the female pelvis.Thirty-six females(age:51,28-73)with cervical carcinoma(n=20),rectal carcinoma(n=7),or uterine fibroid(n=9)were included.Patients underwent magnetic resonance(MR)imaging at a 3T scanner with the sequences of 3D-SPACE,CS-SPACE,and twodimensional(2D)T2-weighted turbo-spin echo(TSE).Quantitative analyses of estimated SNR and relative CNR between tumors and other tissues,image quality,and tissue conspicuity were performed.Two radiologists assessed the difference in diagnostic findings for carcinoma.Quantitative values and qualitative scores were analyzed,respectively.The estimated SNR and the relative CNR of tumor-to-muscle obturator internus,tumor-to-myometrium,and myometrium-to-muscle obturator internus was comparable between 3D-SPACE and CS-SPACE.The overall image quality and the conspicuity of the lesion scores of the CS-SPACE were higher than that of the 3D-SPACE(P<0.01).The CS-SPACE sequence offers shorter scan time,fewer artifacts,and comparable SNR and CNR to conventional 3D-SPACE,and has the potential to improve the performance of T2-weighted images.

Theory of complex-coordinate transformation acoustics for non-Hermitian metamaterials

Transformation acoustics(TA)has emerged as a powerful tool for designing several intriguing conceptual devices,which can manipulate acoustic waves in a flexible manner,yet their applications are limited in Hermitian materials.In this work,we propose the theory of complex-coordinate transformation acoustics(CCTA)and verify the effectiveness in realizing acoustic non-Hermitian metamaterials.Especially,we apply this theory for the first time to the design of acoustic parity-time(PT)and antisymmetric parity-time(APT)metamaterials and demonstrate two distinctive examples.First,we use this method to obtain the exceptional points(EPs)of the PT/APT system and observe the spontaneous phase transition of the scattering matrix in the transformation parameter space.Second,by selecting the Jacobian matrix's constitutive parameters,the PT/APT-symmetric system can also be configured to approach the zero and pole of the scattering matrix,behaving as an acoustic coherent perfect absorber and equivalent laser.We envision our proposed CCTAbased paradigm to open the way for exploring the non-Hermitian physics and finding application in the design of acoustic functional devices such as absorbers and amplifiers whose material parameters are hard to realize by using the conventional transformation method.

Coherent Perfect Absorption in Higher Order Systems

We investigate the phenomenon of coherent perfect absorption in a high-order system with three passive resonators coupled to a super-surface to form this three-state coherent perfect absorber. The effective parity time (PT) symmetry in the passive system has received much attention, and in this open three-state PT symmetric system, the incident wave is used as the effective gain instead of balancing the material gain and loss. We analyze the variation of coherent perfect absorption of this system with the coupling coefficient of the system by simulation.
