description:
Background In recent years, more than 5 million Venezuelans have left their once prosperous country, with several hundred thousand settling in the United States (US). At present, our understanding of the health risk behavior profiles of Venezuelan émigré youth, and their links with cultural stress, remains limited. Objectives Drawing from a sample of recently-immigrated Venezuelan youth in the US, we aim to identify subtypes of youth according to their involvement in health risk behaviors (i.e., substance use, sexual risk behavior, violence) and assess the associations between class membership and key constructs related to cultural stress theory (i.e., negative context of reception, family communication/support). Method Latent profile analysis and multinomial regression were performed using data from a community-based convenience sample of 402 recently-arrived Venezuelan immigrant youth (ages 10–17; 56% male).ResultsWe identified five subtype classes: (1) “Abstainer” (36%), (2) “Alcohol Only” (24%), (3) “Alcohol/Tobacco” (24%), (4) “Aggression” (8%), and (5) “Multidimensional Risk” (8%). Compared to Class #1, youth in Classes #3 and #5 reported significantly higher levels of negative context of reception and lower levels of family functioning while controlling for demographic factors. Youth in Class #5 reported the lowest levels of family economic hardship and the longest duration in the US. Conclusion It is vital that we support both Venezuelan youth who abstain from risk behavior and, at the same time, develop and implement programs that target the needs of those who are at elevated risk for serious consequences related to substance use, sexual risk behavior, and violence.

description: The stability of a cantilevered elastic sheet in a uniform flow has been studied extensively due to its importance in engineering and its prevalence in natural structures. Varying the flow speed can give rise to a range of dynamics including limit cycle behaviour and chaotic motion of the cantilevered sheet. Recently, the "inverted flag" configuration - a cantilevered elastic sheet aligned with the flow impinging on its free edge - has been observed to produce large-amplitude flapping over a finite band of flow speeds. This flapping phenomenon has been found to be a vortex-induced vibration, and only occurs at sufficiently large Reynolds numbers. In all cases studied, the inverted flag has been formed from a cantilevered sheet of rectangular morphology, i.e. the planform of its elastic sheet is a rectangle. Here, we investigate the effect of the inverted flag's morphology on its resulting stability and dynamics. We choose a trapezoidal planform which is explored using experiment and an analytical theory for the divergence instability of an inverted flag of arbitrary morphology. Strikingly, for this planform we observe that the flow speed range over which flapping occurs scales approximately with the flow speed at which the divergence instability occurs. This provides a means by which to predict and control flapping. In a biological setting, leaves in a wind can also align themselves in an inverted flag configuration. Motivated by this natural occurrence we also study the effect of adding an artificial "petiole" (a thin elastic stalk that connects the sheet to the clamp) on the inverted flag's dynamics. We find that the petiole serves to partially decouple fluid forces from elastic forces and increases the freedom by which the flapping dynamics can be tuned. These results highlight the intricacies of the flapping instability and account for some of the varied dynamics of leaves in nature.

description: We perform the renormalization group analysis on the dynamical symmetry breaking under strong external magnetic field, studied recently by Gusynin, Miransky and Shovkovy. We find that any attractive four-Fermi interaction becomes strong in the low energy, thus leading to dynamical symmetry breaking. When the four-Fermi interaction is absent, the $β$-function for the electromagnetic coupling vanishes in the leading order in $1/N$. By solving the Schwinger-Dyson equation for the fermion propagator, we show that in $1/N$ expansion, for any electromagnetic coupling, dynamical symmetry breaking occurs due to the presence of Landau energy gap by the external magnetic field.

description:
We identify subtypes of Venezuelan youth based on patterns of technology-based communication with friends in their receiving (US) and sending (Venezuela) countries and, in turn, examine the behavioral health characteristics among different “subtypes” of youth. Using data from 402 recently-arrived Venezuelan immigrant youth (ages 10–17), latent profile analysis and multinomial regression are employed to examine the relationships between technology-based communication and key outcomes. We identified a four-class solution: [#1] “Daily Contact in US, In Touch with Venezuela” (32%), [#2] “Daily Communication in Both Countries” (19%), [#3] “Weekly Contact: More Voice/Text Than Social Media” (35%), and [#4] “Infrequent Communication with US and Venezuela” (14%). Compared to Class #1, youth in Classes #2 and #3 report elevated depressive symptomatology and more permissive substance use views. Findings suggest that how youth navigate and maintain transnational connections varies substantially, and that technology-based communication is related to key post-migration outcomes.

description: Using a single N-body simulation ($N=0.14\times 10^9$) we explore the formation, evolution and spatial variation of the phase-space spirals similar to those recently discovered by Antoja et al. in the Milky Way disk, with Gaia DR2. For the first time in the literature, we use a self-consistent N-body simulation of an isolated Milky Way-type galaxy to show that the phase-space spirals develop naturally from vertical oscillations driven by the buckling of the stellar bar. We claim that the physical mechanism standing behind the observed incomplete phase-space mixing process can be internal and not necessarily due to the perturbation induced by a massive satellite. In our model, the bending oscillations propagate outwards and produce axisymmetric variations of the mean vertical coordinate and of the vertical velocity component. As a consequence, the phase-space wrapping results in the formation of patterns with various morphology across the disk, depending on the bar orientation, distance to the galactic center and time elapsed since the bar buckling. Once bending waves appear, they are supported for a long time via disk self-gravity. The underlying physical mechanism implies the link between in-plane and vertical motion that leads directly to phase-space structures whose amplitude and shape are in remarkable agreement with those of the phase-space spirals observed in the Milky Way disk. In our isolated galaxy simulation, phase-space spirals are still distinguishable, at the solar neighbourhood, 3 Gyr after the buckling phase. The long-lived character of the phase-space spirals generated by the bar buckling instability cast doubts on the timing argument used so far to get back at the time of the onset of the perturbation: phase-space spirals may have been caused by perturbations originated several Gyrs ago, and not as recent as suggested so far.

description: Swimming at the microscale has recently garnered substantial attention due to the fundamental biological significance of swimming microorganisms and the wide range of biomedical applications for artificial microswimmers. These microswimmers invariably find themselves surrounded by different confining boundaries, which can impact their locomotion in significant and diverse ways. In this work, we employ a widely used three-sphere swimmer model to investigate the effect of confinement on swimming at low Reynolds numbers. We conduct theoretical analysis via the point-particle approximation and numerical simulations based on the finite element method to examine the motion of the swimmer along the centerline in a capillary tube. The axisymmetric configuration reduces the motion to one-dimensional movement, which allows us to quantify how the degree of confinement affects the propulsion speed in a simple manner. Our results show that the confinement does not significantly affect the propulsion speed until the ratio of the radius of the tube to the radius of the sphere is in the range of $\mathcal{O}(1)-\mathcal{O}(10)$, where the swimmer undergoes substantial reduction in its propulsion speed as the radius of the tube decreases. We provide some physical insights into how reduced hydrodynamic interactions between moving spheres under confinement may hinder the propulsion of the three-sphere swimmer. We also remark that the reduced propulsion performance stands in stark contrast to the enhanced helical propulsion observed in a capillary tube, highlighting how the manifestation of confinement effects can vary qualitatively depending on the propulsion mechanisms employed by the swimmers.

description:
Purpose Previous studies have examined externalizing behaviors among African American youth using variable-centered approaches that study aggression and delinquency separately. However, aggression and delinquency often operate together in shaping adolescent behavior. For this reason, person-centered approaches are essential for identifying subgroups of African American youth using multiple indicators of aggression and delinquency to model the behavioral heterogeneity within this population. We examined the relationship between interpersonal, school, and parenting factors and externalizing behaviors among African American youth. Method Drawing from the National Survey on Drug Use and Health 2015–2018, we conducted latent class analysis based on 5 externalizing behavior indicator variables (i.e., serious fight, attack to harm, stealing, drug selling, handgun carrying) using a sample of 7,236 African American adolescents, aged 12–17. Results We identified a three class solution: Class #1—No Involvement (74.4%), characterized by very low levels of involvement in all of the externalizing behaviors examined; Class #2—Serious fight (23.3%), which is characterized by near-universal involvement in a serious fight, far lower levels of attack to harm, and negligible levels of stealing, drug selling, and handgun caring; and Class #3—Multidimensional externalizing (2.3%), characterized by very high levels of involvement in all of the externalizing variables examined. Conclusion Most African American youth are not involved in externalizing behaviors. It is vital to support both the large majority of African-American youth who are abstaining from externalizing behaviors and to develop/implement programs to address the contextual and interpersonal needs of youth at elevated risk for consequences related to externalizing.

description: With eye tracking being increasingly integrated into virtual and augmented reality (VR/AR) head-mounted displays, preserving users' privacy is an ever more important, yet under-explored, topic in the eye tracking community. We report a large-scale online survey (N=124) on privacy aspects of eye tracking that provides the first comprehensive account of with whom, for which services, and to what extent users are willing to share their gaze data. Using these insights, we design a privacy-aware VR interface that uses differential privacy, which we evaluate on a new 20-participant dataset for two privacy sensitive tasks: We show that our method can prevent user re-identification and protect gender information while maintaining high performance for gaze-based document type classification. Our results highlight the privacy challenges particular to gaze data and demonstrate that differential privacy is a potential means to address them. Thus, this paper lays important foundations for future research on privacy-aware gaze interfaces.

description: We study the structural and thermodynamic properties of a model of point particles interacting by means of a Gaussian pair potential first introduced by Stillinger [Stillinger F H 1976 J. Chem. Phys. 65, 3968]. By employing integral equation theories for the fluid state and comparing with Monte Carlo simulation results, we establish the limits of applicability of various common closures and examine the dependence of the correlation functions of the liquid on the density and temperature. We employ a simple, mean-field theory for the high density domain of the liquid and demonstrate that at infinite density the mean-field theory is exact and that the system reduces to an `infinite density ideal gas', where all correlations vanish and where the hypernetted chain (HNC) closure becomes exact. By employing an Einstein model for the solid phases, we subsequently calculate quantitatively the phase diagram of the model and find that the system possesses two solid phases, face centered cubic and body centered cubic, and also displays reentrant melting into a liquid at high densities. Moreover, the system remains fluid at all densities when the temperature exceeds 1% of the strength of the interactions.

description: Subharmonic response is a well known phenomena in, e.g., deterministic nonlinear dynamical systems. We investigate the conditions under which such subharmonic oscillations can persist for a long time in open systems with stochastic dynamics due to thermal fluctuations. In contrast to stochastic autonomous systems in a stationary state, for which the number of coherent oscillations is fundamentally bounded by the number of states in the underlying network, we demonstrate that in periodically driven systems, subharmonic oscillations can, in principle, remain coherent forever, even in networks with a small number of states. We also show that, {\sl inter alia}, the thermodynamic cost rises only logarithmically with the number of coherent oscillations in a model calculation and that the possible periods of the persistent subharmonic response grow linearly with the number of states. We argue that our results can be relevant for biochemical oscillations and for stochastic models of time-crystals.

description: We consider the creation of kink-antikink pairs of a scalar field $ϕ$ by the scattering of classical wavepackets of a second scalar field, $ψ$, when there are no direct interactions between $ϕ$ and $ψ$. The creation becomes possible only due to a quantum field that interacts with both $ϕ$ and $ψ$. We scan parameter space and find it favorable for kink production when the initial wavepackets have large total energy and wide spatial extent but scatter at low velocities.

description: The generic changes of the electronic compressibility in systems which show magnetic instabilities is studied. It is shown that, when going into the ordered phase, the compressibility is reduced by an amount comparable to the its original value, making charge instabilities also possible. We discuss, within this framework, the tendency towards phase separation of the double exchange systems, the pyrochlores, and other magnetic materials.

description: The Bin Packing Problem is a classic problem with wide industrial applicability. In fact, the efficient packing of items into bins is one of the toughest challenges in many logistic corporations and is a critical issue for reducing storage costs or improving vehicle space allocation. In this work, we resort to our previously published quantum-classical framework known as Q4RealBPP, and elaborate on the solving of real-world oriented instances of the Bin Packing Problem. With this purpose, this paper gravitates on the following characteristics: i) the existence of heterogeneous bins, ii) the extension of the framework to solve not only three-dimensional, but also one- and two-dimensional instances of the problem, iii) requirements for item-bin associations, and iv) delivery priorities. All these features have been tested in this paper, as well as the ability of Q4RealBPP to solve real-world oriented instances.

description: This article discusses the effectiveness of the application of such a method of impact on the bottom-hole zone of the formation as polymer acid treatment. Field data on wells from 21 fields in the west of Bashkortostan, in which polymer acid treatments were carried out, were analyzed. Regression equations for dependent variables are obtained. Comparative forecast data with real data are presented and the degree of error of the obtained equations is determined. The effectiveness of the considered treatment method is compared with the effectiveness of another method of influencing the bottom-hole zone of the formation. The accuracy of the prediction of regression equations is estimated based on the degrees of error obtained.

We calculate the survival probability of reactors antineutrinos at the leading order in the SMEFT expansion, that is including linear effects of dimension-6 operators. It is shown that, at this order, reactor experiments alone cannot probe charged-current contact interactions between leptons and quarks that are of the (pseudo)vector (V$\pm$A) or pseudo-scalar type. We also note that flavor-diagonal (pseudo)vector coefficients do not have observable effects in oscillation experiments. In this we reach novel or different conclusions than prior analyses of non-standard neutrino interactions. On the other hand, reactor experiments offer a unique opportunity to probe tensor and scalar SMEFT operators that are off-diagonal in the lepton-flavor space. We derive constraints on the corresponding SMEFT parameters using the most recent data from the Daya Bay and RENO experiments.

description:
Background Relatively little research has accrued examining risk propensity across racial and ethnic groups, especially across time and at the population level. Aims Using a margin for error framework to conceptualize risk variation among major racial and ethnic groups, we hypothesize that African American and Hispanic adolescents will be less likely to report engaging in dangerous risk taking acts compared to White adolescents. Methods This study examines public-use data collected on risk propensity and risky behaviors among adolescents 12–17 between 2002 and 2018 as part of the National Survey on Drug Use and Health (NSDUH). Results While we observed decreased trends in risk propensity, controlling for demographic factors, we see significantly greater odds of reporting “never” engaging in risk for fun among NH Black (AOR 2.01, 95% CI 1.85–2.18) and Hispanic youth (AOR 1.47, 95% CI 1.37–1.58) as compared to NH White youth. NH Black (AOR 0.74, 95% CI 0.61–0.89) and Hispanic (AOR 0.83, 95% CI 0.71–0.98) youth are also less likely than NH White youth to report “always” taking risks for fun. Moreover, the risk propensity-risky behaviors link was weaker among African American and Hispanic adolescents. Conclusions We find compelling evidence that African American and Hispanic adolescents are less likely to endorse deriving positive reinforcement from potentially dangerous risk taking acts compared to White adolescents. These findings suggest that African American and Hispanic youth may perceive less “margin for error” when navigating their environments.

description: The propagator and corresponding path integral for a system of identical particles obeying parastatistics are derived. It is found that the statistical weights of topological sectors of the path integral for parafermions and parabosons are simply related through multiplication by the parity of the permutation of the final positions of the particles. Appropriate generalizations of statistics are proposed obeying unitarity and factorizability (strong cluster decomposition). The realization of simple maximal occupancy (Gentile) statistics is shown to require ghost states.

Hidden tensor structures

description: Any single system whose space of states is given by a separable Hilbert space is automatically equipped with infinitely many hidden tensor-like structures. This includes all quantum mechanical systems as well as classical field theories and classical signal analysis. Accordingly, systems as simple as a single one-dimensional harmonic oscillator, an infinite potential well, or a classical finite-amplitude signal of finite duration, can be decomposed into an arbitrary number of subsystems. The resulting structure is rich enough to enable quantum computation, violation of Bell's inequalities, and formulation of universal quantum gates. Less standard quantum applications involve a distinction between position and hidden position. The hidden position can be accompanied by a hidden spin, even if the particle is spinless. Hidden degrees of freedom are in many respects analogous to modular variables. Moreover, it is shown that these hidden structures are at the roots of some well known theoretical constructions, such as the Brandt-Greenberg multi-boson representation of creation-annihilation operators, intensively investigated in the context of higher-order or fractional-order squeezing. In the context of classical signal analysis, the discussed structures explain why it is possible to emulate a quantum computer by classical analog circuit devices.

description:
B cells have long been an underutilized target in immune cell engineering, despite a number of unique attributes that could address longstanding challenges in medicine. Notably, B cells evolved to secrete large quantities of antibodies for prolonged periods, making them suitable platforms for long-term protein delivery. Recent advances in gene editing technologies, such as CRISPR-Cas, have improved the precision and efficiency of engineering and expanded potential applications of engineered B cells. While most work on B cell editing has focused on ex vivo modification, a body of recent work has also advanced the possibility of in vivo editing applications. In this review, we will discuss both past and current approaches to B cell engineering, and its promising applications in immunology research and therapeutic gene editing.

description: Recent photoabsorption measurements have revealed a rich fine structure in the collective charge-density excitation spectrum of few-electron quantum dots in the presence of magnetic fields. We have performed systematic computational studies of the far-infrared density response of quantum dots, using time-dependent density-functional theory in the linear regime and treating the dots as two-dimensional disks. It turns out that the main characteristics observed in the experiment can be understood in terms of the electronic shell structure of the quantum dots. However, new features arise if a breaking of the circular symmetry of the dots is allowed, leading to an improved description of the experimental results.

description:
This systematic review and meta-analysis aims to synthesize the efficacy of culturally sensitive prevention programs for substance use outcomes among U.S. adolescents of color (aged 11 to 18 years old) and explore whether the intervention effects vary by participant and intervention characteristics. Eight electronic databases and grey literature were searched for eligible randomized controlled trials through September 2022. Robust variance estimation in meta-regression was used to synthesize treatment effect size estimates and to conduct moderator analysis. After screening, 30 unique studies were included. The average treatment effect size across all substance use outcomes (including 221 effect sizes) was Hedges's g = -0.20, 95% CI = [-0.24, -0.16]. The synthesized effect sizes were statistically significant across types of substances (alcohol, cigarette, marijuana, illicit and other drugs, and unspecified substance use), racial/ethnic groups (Hispanic, Black, and Native American), and different follow-ups (0-12 months, >12 months). Very few studies reported substance use consequences as outcomes and the synthesized effect size was non-significant. Meta-regression findings suggest that the intervention effects may vary based on the type of substance. This meta-analysis found supportive evidence of culturally sensitive prevention programs' efficacy in preventing or reducing substance use among Black, Hispanic, and Native American adolescents. More substance use prevention efforts and evidence is needed for Asian American, Pacific Islander, and multiracial adolescents.

description:
Purpose Most research on driving under the influence (DUI) has relied upon variable-centered methods that examine predictors/correlates of DUI. In the present study, we utilize a person-level approach—latent class analysis (LCA)—to model a typology of individuals reporting DUI. This allows us to understand the degree to which individuals drive under the influence of a particular substance or do so across multiple substance types. Methods We use public-use data collected between 2016 and 2019 from the National Survey on Drug Use and Health. The analytic sample was 189,472 participants with a focus on those reporting DUI of psychoactive substances in the past-year (n = 24,619). LCA was conducted using self-reported DUI of past-year alcohol, cannabis, cocaine, heroin, hallucinogens, and methamphetamine as indicator variables. Results More than 1 in 10 Americans reported a DUI within the past-year. One in five people who reported DUI of one substance also reported DUI of at least one additional substance. Using LCA to model heterogeneity among individuals reporting DUI, four classes emerged: “Alcohol Only” (55%), “Cannabis and Alcohol” (36%), “Polydrug” (5%), and “Methamphetamine” (3%). Rates of risk propensity, drug involvement, illicit drug use disorders, and criminal justice system involvement were highest among members of the “Polydrug” and “Methamphetamine” classes. Conclusion Drug treatment centers should take care to include discussions of the dangers and decision-making processes related to DUI of the full spectrum of illicit substances. Greater investment in drug treatment across the service continuum, including the justice system, could prevent/reduce future DUI episodes.

description:
The present study examined the types of drugs likely to be used by bullies, victims, and bully/victims. Participants comprise African American adolescents from three high schools, one youth church group, two community youth programs, and four public venues in low-income communities in Chicago's Southside. A series of logistic regression analyses and latent class analyses were employed. Victims are likely to use alcohol, marijuana, and lean/krokodil. Bullies were likely to use alcohol and marijuana. Bully/victims were not at risk of any of the substances. Our LCA findings revealed a lower occurrence of substance use among victims although 30% used alcohol and marijuana; more than half of bullies showed high levels of alcohol, marijuana, and lean/krokodil use; a diverse pattern of drug use was shown among bully/victims although their lean/krokodil and crack/cocaine use was higher than other subgroups of bullying. The drugs of choice for African American bullies, victims, or bully/victims are variable.

description: The growth of monolayer hexagonal boron nitride (h-BN) on Ir(110) through low-pressure chemical vapor deposition is investigated using low energy electron diffraction and scanning tunneling microscopy. We find that the growth of aligned single hexagonal boron nitride on Ir(110) requires a growth temperature of 1500 K, whereas lower growth temperatures result in coexistence of aligned h-BN with twisted h-BN The presence of the h-BN overlayer suppresses the formation of the nano-faceted ridge pattern known from clean Ir(110). Instead, we observe the formation of a (1 $\times$ n) reconstruction, with n such that the missing rows are in registry with the h-BN/Ir(110) moiré pattern. Our moiré analysis showcases a precise methodology for determining both the moiré periodicity and the h-BN lattice parameter on an fcc(110) surface.

description:
BACKGROUND: Several million Americans use illicit stimulants every month and national data suggest stimulant use is increasing. However, little evidence exists that examines the prevalence and correlates of driving under the influence of stimulants (DUIS). The present study aimed to provide new evidence on the prevalence of DUIS in the U.S. adult population. METHODS: This study examined data from 170,944 adults 18 and older in the 2016-2019 National Survey on Drug Use and Health. Using Stata and R, we estimated the prevalence and key correlates of DUIS among adults in the United States. RESULTS: The overall prevalence of DUIS was 0.7% among adults in general and 28.3% among past-year stimulant users. Among the full adult sample, the prevalence of DUI cocaine was 0.5% and the prevalence of DUI methamphetamine was 0.3%. More than one in five (21.6%) adults with past year cocaine use reported DUI of cocaine, while nearly one half (47.2%) of adults with past year methamphetamine use reported DUI of methamphetamine. There is also a substantially higher likelihood of driving under the influence of stimulants among individuals reporting early onset of use and among those meeting criteria for cocaine/methamphetamine use disorders. Among adults who used cocaine/methamphetamine, those who reported driving under the influence of stimulants were more than 2 times more likely to experience a depressive episode or psychological distress. CONCLUSION: Findings suggest that prevention/treatment approaches focused on multiple substances as well as mental health needs may be most appropriate for addressing the challenge of DUIS.

description: A measurement of the energy spectrum of recoil electrons from solar neutrino scattering in the Super--Kamiokande detector is presented. The results shown here are obtained from 504 days of data taken between the 31st of May, 1996 and the 25th of March, 1998. The shape of the measured spectrum is compared with the expectation for solar B8 neutrinos. The comparison takes into account both kinematic and detector related effects in the measurement process. The spectral shape comparison between the observation and the expectation gives a chi-square of 25.3 with 15 degrees of freedom, corresponding to a 4.6% confidence level.

description: Time reversal symmetry and magnetoelastic correlations are probed by means of high-resolution volume dilatometry in URu2Si2 at cryogenic temperatures and magnetic fields more than enough to suppress the hidden order state at H_HO(T = 0.66 K) approximately 35 T. We report a significant crystal lattice volume expansion at and above H_HO(T), and even above T_HO, possibly a consequence of field-induced f-electron localization, and hysteresis at some high field phase boundaries that confirm volume involvement. We investigate in detail the magnetostriction and magnetization as the temperature is reduced over two decades from 50 K where the system is paramagnetic, to 0.5 K in the realms of the hidden order state. We find a dominant quadratic-in-field dependence delta L/L proportional to H^2, a result consistent with a state that is symmetric under time reversal. The data shows, however, an incipient yet unmistakable asymptotic approach to linear (delta L/L proportional to 1-H/H_0) for 15 T < H < H_HO(0.66 K) approximately 35 T at the lowest temperatures. We discuss these results in the framework of a Ginzburg-Landau formalism that proposes a complex order parameter for the HO to model the (H,T,p) phase diagram.

description: The spectral problem $(A + V(z))ψ=zψ$ is considered with $A$, a self-adjoint Hamiltonian of sufficiently arbitrary nature. The perturbation $V(z)$ is assumed to depend on the energy $z$ as resolvent of another self-adjoint operator $A':$ $V(z)=-B(A'-z)^{-1}B^{*}$. It is supposed that operator $B$ has a finite Hilbert-Schmidt norm and spectra of operators $A$ and $A'$ are separated. The conditions are formulated when the perturbation $V(z)$ may be replaced with an energy-independent ``potential'' $W$ such that the Hamiltonian $H=A +W$ has the same spectrum (more exactly a part of spectrum) and the same eigenfunctions as the initial spectral problem. The orthogonality and expansion theorems are proved for eigenfunction systems of the Hamiltonian $ H=A + W $. Scattering theory is developed for $H$ in the case when operator $A$ has continuous spectrum. Applications of the results obtained to few-body problems are discussed.
