Authors: Nyeleker Kerkulah P. , Fridayani Helen Dian , Chiang Li-Chun
Published: November 2024

This article explores the impact of the SmartASN, which aims to foster technologically smart employees as digital talent and leaders, who will lead Indonesia to a world-class bureaucracy amidst the global competition sparked by the Industrial Era 4.0 demanding a smart society. The research applied a qualitative method with a case study approach, relying on secondary data collected from newspapers, journals, the SmartASN platform, etc. Using the crosstab feature, the data were interactively analysed with the NVivo 12 plus software. The theory used in this research is the Harvard Model for HRM developed by Michael Beeer. The findings indicate that the transformational impact of the SmartASN on Indonesia’s bureaucracy 4.0 can be seen mainly from HR policies, primarily, employee influence and work systems ensuring that the bureaucratic reform is compliant with relevant laws and a clear picture of the resources and capabilities required to achieve its goals. Further, these policies have resulted in HR outcomes, mainly improved employee competence and cost-effectiveness, contributing to the success of the government’s bureaucratic reform agenda. Lastly, the long-term consequences are expected to strengthen the government and employees’ effectiveness, and societal well-being creating a high-performing bureaucracy equipped to meet the challenges of the digital era.

Published: November 2024

Issues regarding mental disorders have recently arisen, which has motivated this investigation. Some members of the newer generation, known as Gen-Z, are confronted with this issue. The majority of individuals who are affected do not exhibit any sensitivity to the disorder they are experiencing. Consequently, it is the responsibility of educators, including parents and instructors, to assist in the identification or raising awareness of the symptoms of mental disorders in their children. Furthermore, psychotherapy is one of the potential solutions to this issue. Psychotherapy is more than just a cure; it is also a means of preventing and constructing personality. The method of this study is a literature method through searching for various related references. The theoretical framework used by Abu Zayd Al-Balkhi’s psychotherapy theory. Some mental disorders that need to be watched out for are if the following symptoms appear a) emotions in the form of frequent and uncontrollable anger and sadness, b) obsessions of compulsions, and c) unwarranted and excessive panic. Therefore, psychotherapy in Islamic education is important because these symptoms can interfere with their lives. Psychotherapy in Islamic education can be applied in two ways, namely external and internal. External techniques include talking therapy with Qur’ani communication techniques. Internal techniques can be carried out in three stages, namely: a) takhalli, in the form of Muhasabah, dhikr, prayer, fasting; b) tahalli, in the form of Internalization of God’s best names (asmaul husna) and the nature of prophet (shifatunnabi), c) tajalli, character development of gratitude, patience, surrender to God, self-acceptance.

Published: November 2024

Smoking is a behavior that is physically and psychologically harmful to humans. Smoking and the environment are two things that cannot be separated. Smoking behavior starts from adolescence and is more influenced by the environment. One environment that has special characteristics is the environment around the cigarette industry. One of the efforts of the world and the Indonesian government is to reduce smoking behavior through the school environment. The aim of this research is to analyze the smoking ban policy in schools located around the cigarette industry. Researchers used a questionnaire method to reveal demographic data and the number of smokers in schools for 446 students in 6 schools and interviews with educators, school foundations, officers who understand smoking regulations at the Health Service and Education Service, community leaders, religious leaders and teenagers. Data analysis uses thematic analysis. The result is that several themes emerge, namely the form of regulations prohibiting smoking in schools; the role of the cigarette industry in schools and society; teachers’ smoking attitudes and behavior; and kretek city culture education for students. City K apart from having many cigarette industries, there are also cultures related to cigarettes. This directly influences how schools enforce their no-smoking rules in schools.

The transition from a conventional system to an information system-based one entails a greater investment of time from users to adapt. However, this process ultimately results in a better understanding and acceptance of information technology. In this study, the aim is to evaluate the degree of acceptance of information systems within the Department of Research and Community Service at XYZ University. The research utilizes two variables within the TAM framework: PU and PEU. The analysis revealed a significant correlation (Sig. 2-tailed) worth 0.000 < 0.05 between PU (X1) and PEU (X2). This finding indicates a strong correlation between the PU variable (X1) and the acceptance variable. Furthermore, the calculated rvalue for the relationship between PU (X1) and acceptance (Y) is 0.989, which exceeds the value in the rtable 0.254. Therefore, It can be inferred that a correlation exists between the PU variable (X1) also acceptance variable. Similarly, the calculated rvalue for PEU (X2) & Y : 0.991, It also exceeds the rtable value : 0.254, suggesting a correlation PEU variable (X2) and the acceptance variable (Y). It should be noted that the positive calculated r or Pearson correlations indicate a positive correlation between the variables. Therefore, it can be inferred that higher ease of use leads to greater acceptance.

Published: November 2024

Enterprise Architecture (EA) is now indispensable for organizations to manage their business operations, data, infrastructure, and ICT systems. Sugarcane agriculture, using EA, is crucial for augmenting production efficiency for both sugarcane cultivators and researchers. Nevertheless, the sector faces considerable challenges in adopting EA, such as incomplete implementation, insufficient knowledge of technological advancements, suboptimal usability of architectural frameworks, lack of proper documentation, and slow service delivery. Additionally, there is no clear standardization for operating procedures. Some research has tried to tackle these challenges but often fails to systematically outline the steps and requirements for designing an enterprise architecture for SSA. This study aims to utilize EA for the Smart Sugarcane-Agriculture system, emphasizing the unique characteristics of agricultural fields. This research has developed a comprehensive EA model by employing the Zachman Framework (ZF) as an Enterprise Architecture Planning (EAP) methodology. The outputs include mapping the EA model, a list and classification of critical success factors, an EA service and information, a solution concept diagram, and an EA business process modelling to develop SSA. This research helps identify and select the appropriate EA framework for Smart Sugarcane Agriculture, assisting local governments and stakeholders in prioritizing critical factors in developing SSA EA.

Authors: Hamsin Muhammad Khaeruddin , Halim Abdul , Anggriawan Rizaldy
Published: November 2024

The digitalization era has revolutionized Indonesia’s financial landscape through rapid advancements in Financial Technology (fintech), guided by regulatory frameworks such as the Financial Services Authority Regulation No. 10 of 2022 and Law No. 27 of 2022 on Personal Data Protection. This research employs a doctrinal legal approach to analyze these regulations’ impact on digital lending and examines debt collection mechanisms under POJK No. 10 of 2022 and Islamic law. Emphasizing compliance with regulatory standards, the study underscores the importance of ethical debt collection practices in mitigating risks associated with illicit fintech activities. Furthermore, it explores how these practices contribute to building a smart society by fostering consumer awareness of privacy rights and promoting sustainable digital governance. In Islamic law, debt collection is permissible within defined ethical boundaries derived from the Quran, Hadith, and scholarly interpretations. Actions that deviate from these principles contravene Sharia norms and societal values. This research contributes to understanding the intersection of digitalization, consumer privacy, and ethical standards, crucial for advancing smart society initiatives in Indonesia’s evolving fintech sector.

Published: November 2024

This research aims to provide a comprehensive overview of the key considerations for formulating Artificial Intelligence (AI) regulations in Asia, Europe, and America. The study employs normative research, which in this context focuses on analyzing legal frameworks, principles, and regulations governing AI. Data collection techniques include the study of legal documents such as laws and regulations, along with a qualitative analysis using comparative methods. The result of research shown that technological advances are impacting human life at an unprecedented rate. AI has become integral to various sectors, transforming industries, fuelling innovation, and reshaping the way people live and work. However, the rapid rise of AI also raises significant moral, legal, and social concerns. In response, countries like China, Indonesia, the European Union, and the United States have enacted regulations to address these issues. The primary considerations in formulating these regulations include ethical principles, data privacy, algorithmic bias, transparency, explainability, and international collaboration. While the regulatory approaches differ across these regions, they share a common goal: ensuring that AI benefits society while minimizing negative impacts.

Published: November 2024

Merkel cell carcinomas are rare cutaneous malignancies with neuroendocrine features that affect elderly individuals with a history of chronic sun exposure and immunosuppression. More recently, a human viral pathogen, the Merkel cell polyomavirus, has been implicated in the carcinogenesis of this disease. Its particularly aggressive biological behavior, the delay in diagnosis related to the lack of awareness, as well as the paucity of effective therapeutic modalities have historically contributed to the high lethality and dismal prognosis. Although surgery and radiation therapy remain the therapeutic pillars for patients with localized disease, the recognition of its immunogenic potential, with the consequent development and successful implementation of immune checkpoint blockade for those with advanced disease has significantly changed the treatment landscape for these patients. In this review, etiopathogenic, diagnostic and therapeutic aspects related to Merkel cell carcinomas are thoroughly addressed.

Authors: Kozinets V. V. , Khotkevich V. I. , Filips A. Kh.
Published: November 2024

Data from measurements of the electrical resistance were used to study the accumulation of crystal lattice defects during plastic deformation at 4.2 °K and their recovery during annealing in the case of polycrystalline copper. It is shown that the rate of strain in the range 2.5 × 10 −5 − 2.5 × 10−2 sec−1 has no effect on the resistivity increment. A disproportionate increase was observed in the concentration of point defects and the dislocation density as the rate of strain increases. It is established that the ratio of the dislocation portion of the electrical resistance to the dislocation density is independent of the latter. Observations revealed the complex nature of the recovery of the electrical resistance during isochronous annealing of copper strongly strained at 4.2 °K.

Published: November 2024

A modification of the Monte-Carlo method is developed for the statistical modeling of lattice systems with dipole-dipole interaction. A representation of the dipole Hamiltonian in reciprocal space is used in the computations. The phase transition in the antiferromagnetic Ising model with pure dipole interaction is investigated at negative absolute temperatures on the basis of the method proposed. Thermodynamic properties of the model are calculated and the critical point is determined. The results of the machine experiment differ significantly from the predictions obtained by the molecular field method.

Authors: Ivanov B. A. , Krasnov V. P. , Sukstanskii A. L.
Published: November 2024

The phase diagram of a uniaxial ferromagnetic plate is constructed taking account of the possibility of spin reorientation. The possibility of the existence of a phase with an inhomogeneous magnetization distribution, a domain phase, was taken into account. The properties of the domain phase are investigated on the basis of a complete system of micromagnetic equations. The phase transition from the homogeneous phase to the domain phase is investigated. A distribution of the magnetization in the domain phase is obtained near the transition line from the domain to the homogeneous phase.
Fluctuation breakdown of metastable states of magnets in phase transitions
Authors: Borovik A. E. , Nechiporenko I. N.
Published: November 2024

The problem of inhomogeneous states of magnets in the neighborhood of a first order phase transition is examined. The structure and energy of the critical fluctuations are investigated for any degree of metastability for paramagnetic-antiferromagnetic, paramagnetic-ferromagnetic, and antiferromagnetic-ferrimagnetic transitions. The limiting case of critical nuclei is studied for a weak metastability. It is shown that because of magnetostriction there is a definite temperature (or external field) range in which metastable states can exist for an arbitrarily long time in the neighborhood of a first order phase transition point. These ranges are found and a comparison is made with available experimental results for certain magnets on the minimal magnitude of the hysteresis originating at the phase transition. The influence of the specimen surface on nucleus formation in magnets is investigated. It is shown that the near-surface nuclei can diminish the range in which the metastable states are not broken down. The energetic barriers for the formation of near-surface nuclei are determined. The influence of point defects of a crystal on the nucleus formation in a magnet is investigated, and it is shown that their presence can shift the whole phase transition picture to either side in the temperature or the external field depending on the kind of defects and on their concentration in the crystal. Kinetics of the metastable-state breakdown process are investigated. Reduced dynamical equations describing the evolution of fluctuations in magnets are obtained, from which it follows that the subcritical fluctuations will collapse while the post-critical fluctuations will grow; solutions of the fluctuation evolution equations are found without and with magnetostriction taken into account. The times of metastable state breakdown of magnets are estimated.

Authors: Demikhovskii V. Ya. , Shmatkova N. I.
Published: November 2024

The dependence of the velocity of sound on the sound wave amplitude under strong conditions of nonlinearity is found, when the inequality ω0τr≫ 1 is satisfied (ω0 is the characteristic vibration frequency of the particles participating in the wave motion and τr is the relaxation time). A calculation is carried out for both the deformation and the piezoelectric electron–phonon interaction. It is shown that the relative change of velocity of sound in a metal at a power of 102 W/cm2, fed into samples, does not exceed 10−6.

Response of ferromagnetic conductors to an electric field and their electrical fluctuation instability
Authors: Drakin A. E. , Nagaev É. L.
Published: November 2024

The static dielectric permittivity ϵ(q) and the magnetoelectric response λ(q) of a highly degenerate ferromagnetic conductor material (metal or very highly doped semiconductor) are calculated. Owing to the dependence of the electron energies on the magnetic ordering, the response function depends on the temperature. As the temperature rises, under conditions where the Ruderman–Kittel theory of indirect exchange is applicable, the dielectric permittivity changes slightly, but above a certain temperature T1 below the Curie point it decreases in an almost jumplike fashion ceasing to be positive-definite. The screening radius and the amplitude of the screening potential both become infinite. This means that the uniform ferromagnetic state of the conductor has become unstable. This could possibly explain the observed changes from ferromagnetic ordering to helicoidal ordering in rare-earth metals.
Low-temperature exchange narrowing of the ESR line
Authors: Sabirov R. Kh.
Published: November 2024

The relaxation function method (Kubo–Tomita theory) is generalized to arbitrary temperatures on the basis of the admissibility of a semiinvariant representation for the correlation functions. The given generalization is used to investigate the exchange-narrowing effect at low temperatures, for which the odd-order moments of the magnetic resonance line are nonvanishing. On the assumption of a Gaussian distribution function for the local field, expressions are derived for calculating the shift and width of the resonance line. It is shown that the shift is nonzero even when the first moment of the line is zero. It is suggested that the isotropic exchange-coupling parameter between identical spins can be determined from measurements of the shift of the resonance line.
Viscoelastic properties and acoustic relaxation in liquid methane-argon mixtures
Authors: Mikhailenko S. A. , Dudar’ B. G. , Derkach V. N.
Published: November 2024

The shear viscosity ηs and sound attenuation α were measured in liquid methane-argon mixtures in equilibrium with saturated vapors at temperatures of 90 to 180°K and frequencies of 15 to 126 MHz. It is established that the shear viscosity ηs and the “high-frequency” volume viscosity ηVhf are nonmonotonic functions of the composition and substantially different. The rotational degrees of freedom of the CH4 are shown to affect the values of ηs and ηVhf, primarily because of the angular momentum contributions. Dilution of the system with argon has almost no effect on the configurational relaxation times but it does substantially retard the relaxation in momentum space. Acoustic relaxation associated with the excitation and deactivation of intramolecular vibrations occurs at lower temperatures in solutions than in pure CH4 and the relaxation frequency decreases as the argon concentration increases. It is shown that these effects are due to the dependence of the probability of the respective energy transitions on the spectral intensity of the mean force autocorrelator.
Tensor structure of the electrostatic interaction Hamiltonian in the Hubbard representation, and its application to magnetically ordered crystals
Authors: Loginov A. A. , Popov V. A.
Published: November 2024

A representation of the electrostatic interaction Hamiltonian is obtained which is analogous to the Hubbard representation, but is explicitly invariant with respect to the spin rotations. Using this representation, we investigate the equivalent Hamiltonian for spin excitations, and obtain the temperature dependences of the site spin moment and effective exciton Hamiltonian.
Energy band splitting phenomenon in intercalated dielectrics
Authors: Katrunov K. A. , Koshkin V. M. , Mil’ner A. P. , Shevchenko S. I.
Published: November 2024

It is shown experimentally that during intercalation the donor organic molecules are aligned along the dielectric and semiconductor crystal layers, whereupon the lattice period formed from the organic molecules is greater than or a multiple of the initial lattice period a0 of the hexagonal crystal PbI2. The lattice period a for quinoline and aniline is 4a0, for nonylamine is 5a0, for decylamine is 6a0, and for dimethylcetylamine is 7a0. The appearance of a long-period modulating potential results in splitting of the conduction and valence bands of the initial crystal, where the multiplicity of the splitting equals the multiplicity of the increase in the lattice period. Splitting of the energy bands is established experimentally by means of diffuse reflection optical spectra of PbI2 intercalated by organic molecules. Charge transfer from the organic molecules to the crystal-matrix results in complete filling of the lower subband in the conduction band.
Experimental study of the equation of state of helium isotopes (4He and 3He) over the temperature range from 3.3°K to 14°K
Authors: Bogoyavlenskii I. V. , Karnatsevich L. V. , Konareva V. G.
Published: November 2024

The P-V-T relations for the helium isotopes 3He and 4He are studied experimentally by the method of determining the dielectric constant of the substances in a UHF cavity resonator. The measurements are conducted in the temperature ranges from the critical points of the isotopes up to ∼ 14°K, which have not previously been investigated practically. For 3He and 4He, measurements of the molar volumes are made along 11 isotherms and 6 isobars. The data obtained about the equations of state of the helium isotopes are found to be in good agreement with the results available in the literature for adjoining temperature regions. Our results for 4He are found to be in satisfactory agreement with the only known measurements of Hill and Lounasmaa in the temperature range investigated.

It is shown that the internal structure of the soliton should undergo pronounced changes with the temperature in this region.
Effect of impurities and temperature on singularities of the magnetic susceptibility of metals
Authors: Vorontsov S. A. , Dolgopolov D. G.
Published: November 2024

Impurity- and temperature-induced broadening of the magnetic susceptibility singularities at extreme points of the energy spectrum is considered. Assuming that the electron damping Γ in the vicinity of the extreme points is independent of the electron momentum, an equation is obtained expressing the thermodynamic potential Ω of a system with impurities in terms of Ω0, the thermodynamic potential of the pure metal. This equation makes it possible to derive expressions describing the impurity broadening of singularities of any electronic properties of the system. The example of the two-band model is used to show that the expansion of the susceptibility in powers of T and Γ at critical points starts with terms proportional to T1/2 and T1/2, respectively. A numerical calculation of the impurity broadening of the orbital susceptibility anomalies at critical points in the given model also indicates that for small Γ(Γ ≪ Δ, where 2Δ is the energy gap) this broadening can be described by introducing an effective temperature.
Temperature and magnetic field dependence of electrical resistivity in indium-doped CdCr2Se4 single crystals. Temperature-driven metal–semiconductor transition
Authors: Koroleva L. I. , Tovmasyan L. N.
Published: November 2024

The electrical resistivity ρ of single crystals of Cd1−xInxCr2Se4 (0.012 ≤ x ≤ 0.051) and Cd0.957Ga0.043Cr2Se4 is studied over the temperature range T = 2−200°K in magnetic fields of up to 50 kOe. Three characteristic types of ρ(T) curves were observed, all of which have a peak near 150°K, the position and size of which are strongly affected by the magnetic field. For weakly doped specimens, a minimum was found near 50°K which is followed by a sharp increase in ρ with decrease in temperature. For specimens with x = 0.051 and for Cd0.957Ga0.043Cr2Se4 no such minimum was observed: in these cases below 12°K there was a sharp drop in ρ, while in the first composition a metal–semiconductor transition took place. The transition may be explained by formation of collective ferron states above the transition point.
Low-temperature quantized susceptibility oscillations and magnetization instability in the electron gas in a metal
Authors: Bagaev V. N. , Okulov V. I. , Pamyatnykh E. A.
Published: November 2024

Quantum oscillations in the magnetic susceptibility due to the electrons in an isotropic metal are considered under conditions such that the amplitude of the oscillatory part of the state density is of the order of the classical value. It is shown that the Fermi-liquid interaction of the electrons makes a substantial contribution to the shape of the oscillations under these conditions, and this can result in instabilities of a new type. The oscillatory part of the susceptibility is calculated without restricting the Fermi-liquid parameters, and instabilities with respect to homogeneous and inhomogeneous perturbations are discussed (the perturbations may be inhomogeneous in a plane perpendicular to the quantizing field).

Anomalies in the electrical properties of bismuth-antimony alloy thin films. I. Changes in the properties with varying composition
Authors: Bukhshtab E. I. , Komnik Yu. F. , Nikitin Yu. V.
Published: November 2024

Changes in the electrical resistivity, in the magnetoresistivity coefficient, and in the Hall coefficient with varying composition of Bi1−x Sbx alloys were studied at 4.2°K on specimens in the form of epitaxial thin films. The antimony content x was varied from 0.01 to 0.20 and the thickness of specimens was varied from 3000 to 20,000 Å. A departure from expected changes in the properties of films was found within the semimetal range and an absence of transition to the semiconducting state at x ≈ 0.065, unlike in the case of certain properties characterizing bulk crystals of Bil−xSbx alloys. These anomalies are explained by curving of the film potential near the surface and, consequently, are attributable to the boundedness in one dimension of these alloy thin-films.

Investigation of peculiarities in the temperature dependence of the thermal conductivity of Pbl2 and ln4Se3 layer crystals at low temperatures
Authors: Anders É. E. , Volchok I. V. , Sukharevskii B. Ya.
Published: November 2024

Results are presented of the experimental investigation of the thermal conductivity of Pbl2 and In4Se3 single crystals parallel to the plane of the layers in the temperature range 2–30°K. The ranges of influence of Umklapp and boundary scattering processes on the phonon thermal conductivity have been determined. It is shown that in the first range (above 10°K) a peculiarity in the phonon spectrum of the quasi-two-dimensional structures, namely, the presence of a bending branch, is manifest; in the second range (below 4°K) phonon scattering on block boundaries proceeds in the same way as in three-dimensional crystals.

Microcontact phonon spectroscopy in the dirty limit
Authors: Kulik I. O. , Yanson I. K.
Published: November 2024

Second voltage derivatives of the current through metallic microcontacts with short (or medium) electron mean free path li as compared with the hole diameter d are investigated. Despite the considerable background present (the smooth dependence of d2I/dV2 on V), the position of the main features of the microcontact spectra on the energy axis remains the same as in pure contacts. This facilitates the use of microcontact spectroscopy as a tool for the study of disordered systems, such as alloys, amorphous films, and heavily deformed materials. Calculations show that the electron–phonon scattering structure factor K(p, p′) depends on the ratio li/d and does not lead to the formation of a background. The latter is due to the nonequilibrium in the phonon system for large contact radii, i.e., high injection currents.
Low-energy localized states in a ferromagnetic semiconductor with magnetic impurities
Authors: Petrova T. G.
Published: November 2024

The low-energy localized states appearing in the spectrum of a ferromagnetic semiconductor doped with magnetic impurities are investigated. Both ferro- and antiferromagnetic type s-d exchange of an electron with lattice atoms are considered. In the investigation of impurity states both direct and s-d exchange interactions are taken into account. The energies of localized states lying below the continuous spectrum and corresponding to the ground state of the system are calculated. It is shown that allowance for the direct exchange has considerable influence on the depth and spectral position of these levels, leading to qualitatively new results.
Penetration of longitudinal electric fields into superconductors containing paramagnetic impurities
Authors: Galaiko V. P. , Glushchuk N. I.
Published: November 2024

We have studied the spatial structure of the nonequilibrium current in the neighborhood of a junction between a normal metal and a superconductor containing a small concentration of paramagnetic impurities Δ τ ≫ 1, Δ τs ≫ 1. Branch mixing leads to penetration of a longitudinal electric field into the superconductor to a depth δ ≫ ξ (T). Due to the energy dependence of the branch mixing frequencies, the energy distribution of the electrons in the normal metal near the junction differs from the usual one. We estimate the influence of this kinetic effect on the thermoelectric energy flux in the normal metal near the junction.
Study of the composition of the barrier layer and various mechanisms of adsorption of molecules in tunnel contacts on aluminum base
Authors: Shklyarevskii O. I. , Lysykh A. A. , Yanson I. K.
Published: November 2024

A study has been made of tunnel contacts with an aluminum base electrode. Plasma oxidation of aluminum films at temperatures up to 250° C has been shown to result in the formation of an aluminum hydroxide barrier layer. The nature of the adsorption centers on the surface of the thin oxide films on aluminum has been determined. Qualitative analysis of the intensity of bands in the tunnel spectrum of symmetric molecules indicates a change in the symmetry of the molecules, apparently occurring under the effect of the internal field of the junction.

The brain is thought to execute cognitive control by actively maintaining and flexibly updating patterns of neural activity that represent goals and rules. However, while actively maintaining patterns of activity requires robustness against noise and distractors, updating the activity requires sensitivity to task-relevant inputs. How these conflicting demands can be reconciled in a single neural system remains unclear. Here, we study the prefrontal cortex of monkeys maintaining a covert rule and integrating sensory inputs toward a choice. Following the onset of neural responses, sensory integration evolves with a 70 ms delay. Using a stability analysis and a recurrent neural network model trained to perform the task, we show that this delay enables a transient, system-level destabilization, opening a temporal window to selectively incorporate new information. This mechanism allows robustness and sensitivity to coexist in a neural system and hierarchically updates patterns of neural activity, providing a general framework for cognitive control. Furthermore, it reveals a learned, explicit rule representation, suggesting a reconciliation between the symbolic and connectionist approaches for building intelligent machines.

Actin cytoskeleton drives the targeted transport of cell wall components to sustain the tip growth of pollen tubes for double fertilization; however, the underlying mechanism remains largely unknown.
Arabidopsis
formin 5 (AtFH5), an actin-nucleating protein, localizes at secretory vesicles and mediates actin polymerization-based vesicle trafficking in pollen. Here, we demonstrate that AtFH5 determines the recruitment and transport of cell wall components in AtFH5-labeled vesicles during the tip growth of pollen tubes. Through a screen of interacting proteins of AtFH5, we identify many cell wall–related proteins, with arabinogalactan protein 23 (AGP23) occupying the highest frequency. AtFH5 interacts with AGP23 via its N-terminal extracellular domain (ECD) and jointly regulate the pollen germination and tube growth process. Further observations reveal that AGP23 co-localizes with AtFH5 at moving vesicles, germination sites, and pollen tube tips, suggesting that AGP23 is delivered by AtFH5-labeled vesicles. Deletion of the ECD of AtFH5 interrupts the dynamic localization and cell-wall connection of AGP23 in pollen grains and tubes. Cytological and genetic evidence shows that AGP23 and AtFH5 work in the same pathway to modulate cell wall composition. Together, our data uncover a role of formin in directing the sorting and deposition of cell wall components via secretory vesicle trafficking during pollen germination and tube growth.
Global hinge sites of proteins as target sites for drug binding
Authors: Zhang Haotian , Gur Mert , Bahar Ivet
Published: November 2024

Hinge sites of proteins play a key role in mediating conformational mechanics. Among them, those involved in the most collective modes of motion, also called global hinges, are of particular interest, as they support cooperative rearrangements that are often functional. Yet, the utility of targeting global hinges for modulating function remains to be established. We present here a systematic study of a series of proteins resolved in drug-bound forms to examine the probabilistic occurrence of spatial overlaps between hinge sites and drug-binding pockets. Our analysis reveals a high propensity of drug binding to hinge sites compared to random. Notably, one-third of currently approved drugs are colocalized with hinge sites. These mechanosensitive sites are predictable by simple models such as the Gaussian Network Model. Their targeting thus emerges as a viable strategy for developing a new class of drugs that would exploit and modulate the target proteins’ intrinsic dynamics, and potentially alleviate drug-resistance when used in combination with orthosteric or allosteric drugs.
Introduction

Published: November 2024

Chapter 1 defines Experiential Therapy and how it differs from traditional talk therapy. It also discusses the philosophy of “Challenge by Choice” which guides Experiential Therapy. Through the Challenge by Choice philosophy, the client is always empowered to make a choice about whether they participate, their duration of participation, and the quality of their participation. The clinician always follows the lead of the client. Chapter 1 discusses how Challenge by Choice fits well with a trauma-sensitive approach. Clinical segues are introduced as a clinical intervention that connects the Experiential Therapy activity to the clients’ real life. Clinical segues transfer the learning from what just happened in the Experiential Therapy activity to what can be taken with the client today, tomorrow, and always. The relationship between mindfulness and Experiential Therapy is initially discussed. Additionally, two Experiential Therapy activities are shared.
Integrating Mindfulness With Experiential Therapy
Authors: Laser Julie Anne , Nicotera Nicole
Published: November 2024

This chapter shares how mindfulness honors the traditions, cultures, and systems of medicine from which it arises. Research evidence is presented of how mindfulness practices support healing and recovery for clients. The benefits of integrating mindfulness practices into Experiential Therapy are explored. Mindfulness approaches take the stance that “problems are viewed as opportunities for growth” and encourage clients to understand problems as part of life, that life will always bring challenges, and the goal is to learn how to navigate them (Lee et al., 2009, p. 312). This stance pairs well with Experiential Therapy, which has the goal of learning through experience and applying that learning to the next challenges one will face. Particular importance is placed on how mindfulness practices and Experiential Therapy are a good fit for working with survivors of trauma.
Fine-Tuning for the Clinician

In Chapter 5, “Fine-Tuning for the Clinician: Capacities for Well-Being and Working Across Identities,” the authors discuss the process of fine-tuning oneself to practice habits of wellness and to work across the multiple identities that clients possess. There are two aspects of being a mental health clinician that are always present and always challenging. One of these is therapist well-being and active strategies for self-care. The other aspect is the clinician’s fine-tuning to build the capacity for working across client identities, especially clients with minoritized identities. This chapter addresses both of these aspects with a view to the necessity of lifelong learning and growth in both areas.
Experiential Therapy Activities With Specific Populations
Authors: Laser Julie Anne , Nicotera Nicole
Published: November 2024

Chapter 10 discusses Experiential Therapy activities with specific populations: children, youth, couples, and families. The authors discuss particular considerations and specific strategies for working with children, youth, couples, and families when doing Experiential Therapy. They share three examples of scaled Experiential Therapy activities for children. The authors point out that Experiential Therapy a great assessment tool with children because they show up as themselves and not as try to present as a version of themselves. They also provide three examples of scaled Experiential Therapy activities for youth. The authors describe three examples of scaled Experiential Therapy activities for couples, and they discuss doing Experiential Therapy in nature with couples. They also point out that experiential therapy is useful for illuminating three components that are integral for healthy couples: passion, intimacy, and commitment. The chapter concludes with three examples of scaled Experiential Therapy activities for families, as well.
Evaluating Experiential Therapy in Your Practice and Conclusions
Authors: Laser Julie Anne , Nicotera Nicole
Published: November 2024

Chapter 12 concludes with how to evaluate Experiential Therapy’s effectiveness in the reader’s organization or practice. The authors share the survey instruments they have created, which have been vetted by the Institutional Review Board (IRB) at their university, so that the reader can know not just anecdotally, but scientifically, that Experiential Therapy works in their practice. They have separated the survey instruments into three different categories: (1) ongoing Experiential Therapy, (2) an eight-hour Challenge Course day with an Experiential Therapist, and (3) Logos Experiential Therapy trips with human trafficking survivors (discussed in Chapter 11). Each type of Experiential Therapy activity necessitated a different research survey instrument. Additionally, in the conclusion the authors discuss their enjoyment of the modality of Experiential Therapy and their willingness to communicate and share this knowledge with others.
Introduction
Authors: Glauthier Patrick
Published: November 2024

The sublime is an experience of transcendence, often described as wonder, awe, stupefaction, ecstasy, or even terror. The scientific sublime is the experience of sublimity through or in connection with the investigation of the natural world. Most studies of the sublime in Greek and/or Latin literature read individual passages through the lens of one or more theorists of the sublime, especially Longinus, Burke, and Kant. For scholars of Latin literature, Lucretius now functions as a de facto theorist, and De rerum natura has become an important touchstone for the field. This book, however, decenters all such theorists. While De rerum natura is an essential model and intertext for Manilius, Seneca, Lucan, and the Aetna poet, this study demonstrates that the histories of the sublime and the investigation of nature at Rome include dimensions and narratives that are unrelated to or not primarily dependent on Lucretius’s poem.
Aetna and the Wonders of the Earth
Authors: Glauthier Patrick
Published: November 2024

The Aetna poet urges readers to study the earth, rather than the heavens or atmosphere, and to celebrate its wonders. Aetna’s volcanism provides scope for both pursuits, which powerfully induce the experience of sublimity: to read the poem is to undertake a harrowing journey through a volatile landscape, to be dazzled by stupendously engineered machines at an imperial spectacle, to catch sight of a mysterious goddess, nature the demiurge. Ultimately, the poet subordinates the study of nature’s causes to the awed contemplation of her marvels, exemplified by the story of the pious brothers of Catania. After the depravations of Nero’s regime, the imperviousness of some natural phenomena to causal analysis thrills and ennobles. This is the perspective of paradoxography, and the enthusiastic combination of philosophical theory with paradoxographical wonder constitutes the poem’s volcanic aesthetics. Significantly, the commitment to paradoxography fits the times, connecting the Aetna poet with Longinus and the Elder Pliny.
