description: In the aftermath of COVID-19, blended learning (BL) has emerged as the dominant mode of learning. With our university transitioning to a new campus where BL is expected to seamlessly integrate into its physical design, it is anticipated to become an indispensable component of the student experience. However, there appears to be a paucity of research into students’ perceptions of digital support and satisfaction with interactions within BLEs at higher education, especially in the post-COVID-19 era. In this paper, we utilize the learning analytics (LA) cycle as an overarching framework to shape our study’s methodology. Our aim was to examine students’ perceptions of digital relatedness support (DRS) and satisfaction with learner-technology interaction (SLTI) across three modules (n = 305) at our university. To achieve this objective, we conducted a cross-sectional survey complemented by focus group discussions (FGDs). Over 50% of respondents had positive perceptions of DRS and SLTI. In addition, statistically significant differences were observed between two pairs and one pair of modules for DRS and SLTI, respectively. The FGD data provided some possible reasons for the differences in DRS and SLTI scores across modules. This paper concludes with some recommendations to enhance DRS and SLTI.

description: Статья посвящена исследованию личностной организации лиц с гомосексуальной
ориентацией. Сделан акцент на необходимости отличать истинную гомосексуальность от ее транзиторной формы, являющейся формой выражения протестной подростковой позиции. В тексте доказывается,
что уровень развития личности лиц с истинной гомосексуальной ориентацией соответствует пограничной личностной организации. Для диагностики критериев пограничного уровня развития личности использованы признаки, описанные в Диагностическом и статистическом руководстве по психическим
расстройствам (DSM-5), Международной классификации болезней 10-го и 11-го пересмотра (МКБ-10 и
11), а также в руководстве по психодинамической диагностике (PDM-2): предпочитаемые психологические защитные механизмы; уровень развития личности; способность к рефлексии; природа основного
конфликта; особенности отношений с психологом, а также наличие или отсутствие хронических депрессии, чувства опустошенности, вины, гнева или частых вспышек аффекта, тревоги, чувства одиночества,
скуки, пустоты. В статье описаны методики исследования данных феноменов, приведены доказательства
признаков пограничной личностной организации у лиц с гомосексуальной ориентацией.
description: The article is devoted to the study of personality specifics of people with homosexual
tendencies in the northern region. The article focuses on the need of distinguishing between true homosexuality and its transient form, which is a form of expression of a remonstrative adolescent
position. It is proved in the text that the level of personality development in people with true
homosexual tendencies corresponds with the borderline personality organization. To diagnose the
criteria of the borderline level of personality development, the following features described in
Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), International Classification
of Diseases, 10th and 11th Edition (ICD-10 and 11) and Psychodynamic Diagnostic Manual,
2nd edition (PDM-2) were used: preferred psychological mechanisms of defense; the level of personality
development; the ability of reflective thinking; basic conflict nature; specifics of relations
with a psychologist. Also, the presence or absence of the following chronic states were taken into
account: depression; feeling of emptiness; feeing of guilt; anger or frequent fits of passion; anxiety;
feelings of loneliness, boredom, emptiness. The article describes methods of studying these phenomena
and provides proofs of signs of borderline personality organization in people with
homosexual tendencies.

description: Ocean turbulence dissipation rate is estimated either by means of microstructure shear measurements, or by adiabatically reordering vertical profiles of density. The latter technique leads to the estimate of the Thorpe scale, which in turn can be used to obtain average turbulence dissipation rate by comparing the Thorpe scale to the Ozmidov scale. In both cases, the turbulence dissipation rate can be estimated using single vertical profiles from shipborne instrumentation. We present here an alternative method to estimate the length scale of overturns by using the Ellison length scale. The Ellison scale is estimated from temperature variance just beyond the internal wave band, measured by moored instruments. We apply the method to high resolution temperature data from two moorings deployed at different locations around the Josephine seamount (North Eastern Atlantic Ocean), in a region of bottom-intensified turbulence. The variance of the temperature time series just above the internal wave frequency band is well correlated with the Thorpe scale. The method is based on the time--frequency decomposition of variance called "maximum overlap discrete wavelet transform". The results show that the Ellison length scale can be a viable alternative to the Thorpe scale for indirectly estimating turbulence dissipation rate from moored instruments in the ocean if time resolution is sufficiently high. We suggest that fine structure contaminated temperature measurements can provide reliable information on turbulence intensity.

description: Background: The main limitation of cell therapy in Parkinson’s disease is the poor graft survival upon transplantation. Biomaterials – like injectable collagen hydrogels – can help to enhance the survival of the grafted cells since they act as an adhesion matrix as well as a barrier from the host immune response. The site specific delivery of anti-inflammatory factors using injectable biomaterial scaffolds has the potential to target the elevated inflammatory response present after cell transplantation therapy in Parkinson’s disease and therefore increase graft survival. Aims: The aims of these studies were to assess if the collagen hydrogels could retain IL-10 in the striatum and if the IL-10 had any beneficial effects in cell survival, re-innervation and the host immune response. Methods: In vivo, male Sprague Dawley rats were given a bilateral intra-striatal delivery of 1000 ng of IL-10 as a bolus or encapsulated in collagen hydrogels. Polymerisation, biocompatibility, biodegradability and IL-10 retention were assessed at days 1, 2 and 4 using immunohistochemistry. In another in vivo study, parkinsonian rats were injected with primary dopaminergic cells (400.000 cells) with or without IL-10 (1000 ng) and in a collagen hydrogel or alone and were sacrificed 12 weeks post-transplantation. Graft survival, re-innervation and the host immune response were analysed. Results: The injection of IL-10 within the collagen hydrogel resulted in significant retention of the anti-inflammatory cytokine in the striatum, and reduced the host microglial response at the site of administration at early timepoints. Despite the fact that IL-10 reduced striatal microgliosis at 4 weeks post-transplantation, IL-10 did not increase cell survival in the grafts nor decrease the host immune response at 12 weeks after transplantation. Conclusion: Although IL-10 is a potent anti-inflammatory cytokine that reduced the striatal microgliosis at early timepoints after transplantation, this fact did not have any effects in the long term survival of the grafted cells.

Effects of the hydration process on kinetics of carbonation of lime

description: Research on the carbonation step in the cycle of Ca-rich lime is crucial to understand its applications in modern construction as well as in cultural heritage conservation. While studying this process, one can notice that the details of the hydration process of Ca(OH)2 play an important role in the carbonation process that follows it. There is work on the process of crystallization of Ca(OH)2 and its conversion to Ca(CO)3, but not so many implications of how the water molecules interact during the process of hydration. Following the work of J. Park et al., we want to see how the reaction between Ca(OH)2 and water molecules later affects its carbonation, from a kinetic point of view and is there really the step of “water intercalation” between the layers of calcium hydroxide upon its hydration. For this preliminary research, we have used hydrated lime, which was fully dried, so we can avoid any former hydration. Later, the material was hydrated in two different ways, the first one being exposure of the material to water vapor (closed system with around 90% of relative humidity), in the absence of CO2, for 7 days. The second method was immersing the sample directly into lime water (saturated solution of Ca(OH)2), letting it to react for one hour. After hydration process, XRD analysis was done for both samples. Later on, carbonation process will be tested for both types of hydrated Ca(OH)2, with the means of TGA and SEM analysis.

description: The first proof of well-posedness of an initial boundary value problem for the Einstein equations was given in 1999 by Friedrich and Nagy. They used a frame formalism with a particular gauge for formulating the equations. This `Friedrich-Nagy' (FN) gauge has never been implemented for use in numerical simulations before because it was deemed too complicated. In this paper we present an implementation of the FN gauge for systems with two commuting space-like Killing vectors. We investigate the numerical performance of this formulation for plane wave space-times, reproducing the well-known Khan-Penrose solution for colliding impulsive plane waves and exhibiting a gravitational wave `ping-pong'.

description: The notion of distance defined on the set of states of a composite quantum system can be used to quantify total, quantum and classical correlations in a unifying way. We provide new closed formulae for classical and total correlations of two-qubit Bell-diagonal states by considering the Bures distance. Complementing the known corresponding expressions for entanglement and more general quantum correlations, we thus complete the quantitative hierarchy of Bures correlations for Bell-diagonal states. We then explicitly calculate Bures correlations for two relevant families of states: Werner states and rank-2 Bell-diagonal states, highlighting the subadditivity which holds for total correlations with respect to the sum of classical and quantum ones when using Bures distance. Finally, we analyse a dynamical model of two independent qubits locally exposed to non-dissipative decoherence channels, where both quantum and classical correlations measured by Bures distance exhibit freezing phenomena, in analogy with other known quantifiers of correlations.

description: We study electromagnetic field propagation through an ideal, passive, triangular three-waveguide coupler using a symmetry based approach to take advantage of the underlying $SU(3)$ symmetry. The planar version of this platform has proven valuable in photonic circuit design providing optical sampling, filtering, modulating, multiplexing, and switching. We show that a group-theory approach can readily provide a starting point for design optimization of the triangular version. Our analysis is presented as a practical tutorial on the use of group theory to study photonic lattices for those not familiar with abstract algebra methods. In particular, we study the equilateral trimer to show the relation of pearl-necklace arrays with the Discrete Fourier Transform due to their cyclic group symmetry, and the isosceles trimer to show its relation with the golden ratio and its ability to provide stable output at a single waveguide. We also study the propagation dependent case of an equilateral trimer that linearly increases or decreases its effective coupling with the propagation distance. For the sake of completeness, we go beyond the standard optical-quantum analogy to show that it is possible to derive coupled-mode equations for intensity and phase, and that it is also possible to calculate envelopes for the propagation of all possible inputs belonging to an energy class, as well as individual input field amplitudes, without the need of point-to-point propagation.

description: We present an investigation of charge-compensated antiferromagnetic (Ca$_{x}$La$_{1-x}$)(Ba$_{1.75-x}$La$_{0.25+x}$)Cu$_{3}$O$_{y}$ single crystals using Raman scattering as well as muon spin rotation. In this system the parameter $x$ controls the Cu-O-Cu superexchange interaction via bond distances and buckling angles. The oxygen content $y$ controls the charge doping. In the absence of doping the two-magnon peak position is directly proportional to the superexchange strength $J$. We find that both $x$ and $y$ affect the peak position considerably. The Néel temperature determined from muon spin rotation on the same samples independently confirms the strong dependence of the magnetic interaction on $x$ and $y$. We find a considerable increase in the maximum superconducting transition temperature $T_{c}^{max}$ with $J$. This is strong evidence of the importance of orbital overlap to superconductivity in this family of cuprates.

description: In solids, the high density of charged particles makes many-body interactions a pervasive principle governing optics and electronics(1-12). However, Walter Kohn found in 1961 that the cyclotron resonance of Landau-quantized electrons is independent of the seemingly inescapable Coulomb interaction between electrons(2). Although this surprising theorem has been exploited in sophisticated quantum phenomena(13-15), such as ultrastrong light-matter coupling(16), superradiance(17) and coherent control(18), the complete absence of nonlinearities excludes many intriguing possibilities, such as quantum-logic protocols(19). Here, we use intense terahertz pulses to drive the cyclotron response of a two-dimensional electron gas beyond the protective limits of Kohn's theorem. Anharmonic Landau ladder climbing and distinct terahertz four-and six-wave mixing signatures occur, which our theory links to dynamic Coulomb effects between electrons and the positively charged ion background. This new context for Kohn's theorem unveils previously inaccessible internal degrees of freedom of Landau electrons, opening up new realms of ultrafast quantum control for electrons.
Quantum Resistor-Capacitor Circuit with Majorana Fermion Modes in Chiral Topological Superconductor

description: We investigate the mesoscopic resistor-capacitor circuit consisting of a quantum dot coupled to spatially separated Majorana fermion modes in a chiral topological superconductor. We find substantially enhanced relaxation resistance due to the nature of Majorana fermions, which are their own anti-particles and composed of particle and hole excitations in the same abundance. Further, if only a single Majorana mode is involved, the zero-frequency relaxation resistance is completely suppressed due to a destructive interference. As a result, the Majorana mode opens an exotic dissipative channel on a superconductor which is typically regarded as dissipationless due to its finite superconducting gap.

description: Building on recent work of the authors, we use degenerations to chains of elliptic curves to prove two cases of the Aprodu-Farkas strong maximal rank conjecture, in genus $22$ and $23$. This constitutes a major step forward in Farkas' program to prove that the moduli spaces of curves of genus $22$ and $23$ are of general type. Our techniques involve a combination of the Eisenbud-Harris theory of limit linear series, and the notion of linked linear series developed by the second author.
description: 59 pages. v3: Farkas has informed us that his divisor class computation does not suffice to reduce the moduli spaces being of general type to the corresponding cases of the strong maximal rank conjecture: a second type of excess degeneracy also has to be ruled out. We have accordingly removed the implications on the moduli spaces pending further study of the second form of degeneracy

description: Classically, no transfer occurs between two equally filled reservoirs no matter how one looks at them, but the situation can be different quantum mechanically. This paradoxically surprising phenomenon rests on the distinctive property of the quantum world that one cannot stare at a system without disturbing it. It was recently discovered that this seemingly annoying feature could be harnessed to control small quantum systems using weak measurements. Here we present one of the simplest models -- an idealised double quantum dot -- where by toying with the dot measurement strength, i.e. the intensity of the look, it is possible to create a particle flux in an otherwise completely symmetric system. The basic property underlying this phenomena is that measurement disturbances are very different on a system evolving unitarily and a system evolving dissipatively. This effect shows that adaptive measurements can have dramatic effects enabling transport control but possibly inducing biases in the measurement of macroscopic quantities if not handled with care.

description: Motivation: Understanding the structure and interplay of cellular signalling pathways is one of the great challenges in molecular biology. Boolean Networks can infer signalling networks from observations of protein activation. In situations where it is difficult to assess protein activation directly, Nested Effect Models are an alternative. They derive the network structure indirectly from downstream effects of pathway perturbations. To date, Nested Effect Models cannot resolve signalling details like the formation of signalling complexes or the activation of proteins by multiple alternative input signals. Here we introduce Boolean Nested Effect Models (B-NEM). B-NEMs combine the use of downstream effects with the higher resolution of signalling pathway structures in Boolean Networks. Results: We show that B-NEMs accurately reconstruct signal flows in simulated data. Using B-NEM we then resolve BCR signalling via PI3K and TAK1 kinases in BL2 lymphoma cell lines.

description: Direct numerical simulations of Taylor-Couette flow (TC). Shear Reynolds numbers of up to $3\cdot10^5$, corresponding to Taylor numbers of $Ta=4.6\cdot10^{10}$, were reached. Effective scaling laws for the torque are presented. The transition to the ultimate regime, in which asymptotic scaling laws (with logarithmic corrections) for the torque are expected to hold up to arbitrarily high driving, is analysed for different radius ratios $η$, different aspect ratios $Γ$ and different rotation ratios $Ro$. It is shown that the transition is approximately independent of $Ro$ and $Γ$, but depends significantly on $η$. We furthermore calculate the local angular velocity profiles and visualize different flow regimes that depend both on the shearing of the flow, and the Coriolis force originating from the outer cylinder rotation. Two main regimes are distinguished, based on the magnitude of the Coriolis force, namely the co-rotating and weakly counter-rotating regime dominated by Rayleigh-unstable regions, and the strongly counter-rotating regime where a mixture of stable and unstable regions exist. Furthermore, an analogy between $η$ and outer-cylinder rotation is revealed, namely that smaller gaps behave like a wider gap with co-rotating cylinders, and that wider gaps behave like smaller gaps with weakly counter-rotating cylinders. Finally, the effect of $Γ$ on the effective torque versus $Ta$ scaling is analysed and it is shown that different branches of the torque-versus-$Ta$ relationships associated to different aspect ratios are found to cross within $15%$ of the $Re$ associated to the transition to the ultimate regime. The paper culminates in phase diagram in the inner vs outer $Re$ number parameter space and in the $Ta$ vs $Ro$ parameter space, which can be seen as the extension of the Andereck \emph{et al.} phase diagram towards the ultimate regime.

Ziel unseres Projekts war es, die Vollständigkeit und Zuverlässigkeit von medizinischen Lehrbüchern mit Therapieanleitungen zur präklinischen Schlaganfallversorgung zu untersuchen. Lehrbücher sind für Ärzte wie Studenten nach wie vor, trotz der aufkommenden Alternativen in Form digitaler Medien, sehr wichtige Informationsquellen für Examina und medizinische Entscheidungen. METHODEN: Wir führten eine systematische Lehrbuch-Literatursuche gemäß den PRISMA-Kriterien durch. Die Inhalte zur präklinischen Therapie des Schlaganfalls wurden durch zwei unabhängige Untersucher evaluiert. Qualitätsstandard der Evaluation waren die aktuellen Schlaganfall-Leitlinien. Die endgültige Bewertung erfolgte in einem Konsensus Prozess. ERGEBNISSE: Von 68 Lehrbüchern zur Notfallmedizin zwischen 2011 und 2014 konnten 16 mit Inhalten zur präklinischen Therapie des Schlaganfalls bewertet werden. Die meisten untersuchten Lehrbücher zeigten gravierende Auslassungen und Abweichungen im Vergleich zu den Handlungsempfehlungen anerkannter aktueller Leitlinien. In fast allen Büchern fehlten die Quellennachweise. ZUSAMMENFASSUNG: Die meisten Notfallmedizinlehrbücher zur präklinischen Therapie des Schlaganfalls vermitteln momentan nicht die notwendigen Inhalte für eine erfolgreiche Therapie. Wegen fehlender Quellenangaben fehlt den Lesern auch die Möglichkeit Wissensinhalte nachzuvollziehen und zu vertiefen. Es ist dringend notwendig Lehrbuchinhalte auf einen Qualitätsstandard zu bringen, wie er von der evidenz-basierten Medizin gefordert wird.

description: We consider free-fermion chains where full and empty parts are connected by a transition region with narrow surfaces. This can be caused by a linear potential or by time evolution from a step-like initial state. Entanglement spectra, entanglement entropies and fluctuations are determined for subsystems either in the surface region or extending into the bulk. In all cases there is logarithmic behaviour in the subsystem size, but the prefactors in the surface differ from those in the bulk by 3/2. A previous fluctuation result is corrected and a general scaling formula is inferred from the data.

description: Regular functions from infinite words to infinite words can be equivalently specified by MSO-transducers, streaming $ω$-string transducers as well as deterministic two-way transducers with look-ahead. In their one-way restriction, the latter transducers define the class of rational functions. Even though regular functions are robustly characterised by several finite-state devices, even the subclass of rational functions may contain functions which are not computable (by a Turing machine with infinite input). This paper proposes a decision procedure for the following synthesis problem: given a regular function $f$ (equivalently specified by one of the aforementioned transducer model), is $f$ computable and if it is, synthesize a Turing machine computing it.
 For regular functions, we show that computability is equivalent to continuity, and therefore the problem boils down to deciding continuity. We establish a generic characterisation of continuity for functions preserving regular languages under inverse image (such as regular functions). We exploit this characterisation to show the decidability of continuity (and hence computability) of rational and regular functions. For rational functions, we show that this can be done in $\mathsf{NLogSpace}$ (it was already known to be in $\mathsf{PTime}$ by Prieur). In a similar fashion, we also effectively characterise uniform continuity of regular functions, and relate it to the notion of uniform computability, which offers stronger efficiency guarantees.

description: We provide a procedure for resolving, in characteristic 0, singularities of a variety $X$ embedded in a smooth variety $Y$ by repeatedly blowing up the worst singularities, in the sense of stack-theoretic weighted blowings up. No history, no exceptional divisors, and no logarithmic structures are necessary to carry this out; the steps are explicit geometric operations requiring no choices; and the resulting algorithm is efficient. A similar result was discovered independently by McQuillan in a manuscript posted on this archive simultaneously.

description: Shared controlled vocabularies are a prerequisite for collaborative annotation and semantic interchange. The creation and maintenance of such vocabularies is, however, time-consuming and expensive. The diversity of research questions in the humanities makes it virtually impossible to create shared controlled vocabularies that cover a wide range of potential applications and satisfy the needs of diverse stakeholders. In this paper we present a novel conceptual approach for mitigating these problems. We propose that projects define their own vocabularies as needed and link the vocabulary terms to one or more concepts in a reference thesaurus, so that the project-specific term effectively serves as a "label" for a set of shared concepts. We also describe the implementation of this approach in the Labeling System. The Labeling System is a Web application that allows users to easily import concepts or create SKOS vocabularies and link the vocabulary terms to concepts from one or more reference thesauri.

description: A splenic pseudocyst is an encapsulated mature collection located within the splenic tissues. It is usually asymptomatic and is detected incidentally during either radiological workup or laparoscopy for other reasons. Our patient is a 66-year-old male presenting with a history of weight loss, early satiety, and constipation, found to have a splenic pseudocyst communicating with a preexisting pancreatic cyst. Cystic lesions of the spleen can be divided into primary and secondary types. Secondary splenic cysts (pseudocysts) are residues of either earlier infection, trauma, or infarction. Management approaches to splenic cysts are either conservative or surgical according to the symptoms and size of these cysts. Most splenic cysts are discovered incidentally either during radiological workup or laparoscopy. Such entities require the combined effort of surgeons, gastroenterologists, and radiologists to provide the maximum care for these patients.

description: We carry out the extended symmetry analysis of a two-dimensional degenerate Burgers equation. Its complete point-symmetry group is found using the algebraic method, and all its generalized symmetries are proved equivalent to its Lie symmetries. We also prove that the space of conservation laws of this equation is infinite-dimensional and is naturally isomorphic to the solution space of the (1+1)-dimensional backward linear heat equation. Lie reductions of the two-dimensional degenerate Burgers equation are comprehensively studied in the optimal way and new Lie invariant solutions are constructed. We additionally consider solutions that also satisfy an analogous nondegenerate Burgers equation. In total, we construct four families of solutions of two-dimensional degenerate Burgers equation that are expressed in terms of arbitrary (nonzero) solutions of the (1+1)-dimensional linear heat equation. Various kinds of hidden symmetries and hidden conservation laws (local and potential ones) are discussed as well. As a by-product, we exhaustively describe generalized symmetries, cosymmetries and conservation laws of the transport equation, also called the inviscid Burgers equation, and construct new invariant solutions of the nonlinear diffusion and diffusion-convection equations with power nonlinearities of degree -1/2.

description: Machine learning algorithms perform well on identifying patterns in many different datasets due to their versatility. However, as one increases the size of the dataset, the computation time for training and using these statistical models grows quickly. Quantum computing offers a new paradigm which may have the ability to overcome these computational difficulties. Here, we propose a quantum analogue to K-means clustering, implement it on simulated superconducting qubits, and compare it to a previously developed quantum support vector machine. We find the algorithm's accuracy comparable to the classical K-means algorithm for clustering and classification problems, and find that it has asymptotic complexity $O(N^{3/2}K^{1/2}\log{P})$, where $N$ is the number of data points, $K$ is the number of clusters, and $P$ is the dimension of the data points, giving a significant speedup over the classical analogue.

description: Die Dissertation geht der Frage nach, wie sich Menschen, die langzeitarbeitslos sind, mit ihrer Situation auseinandersetzen und auf welche Orientierungsmuster sie zurückgreifen. Da die Bewältigung von Arbeitslosigkeit eng mit der Perspektive auf Erwerbsarbeit, aber auch mit gesellschaftlich vermittelten Orientierungen zusammenhängt, werden Arbeit und Arbeitslosigkeit aus unterschiedlichen Perspektiven beleuchtet. Im empirischen Teil der Studie werden aus einer biographieanalytischen Perspektive Orientierungsmuster Langzeitarbeitsloser herausgearbeitet und in einer Typologie zusammengefasst.

description: We prove that the Galois pseudo-representation valued in the mod $p^n$ cuspidal Hecke algebra for GL(2) over a totally real number field $F$, of parallel weight $1$ and level prime to $p$, is unramified at any place above $p$. The same is true for the non-cuspidal Hecke algebra at places above $p$ whose ramification index is not divisible by $p-1$. A novel geometric ingredient, which is also of an independent interest, is the construction and study, in the case when $p$ ramifies in $F$, of generalised $Θ$-operators using Reduzzi--Xiao's generalised Hasse invariants, including especially an injectivity criterion in terms of minimal weights.

description: We introduce the notion of finite BRST-antiBRST transformations for constrained dynamical systems in the generalized Hamiltonian formalism, both global and field-dependent, with a doublet $λ_{a}$, $a=1,2$, of anticommuting Grassmann parameters and find explicit Jacobians corresponding to these changes of variables in the path integral. It turns out that the finite transformations are quadratic in their parameters. Exactly as in the case of finite field-dependent BRST-antiBRST transformations for the Yang--Mills vacuum functional in the Lagrangian formalism examined in our previous paper [arXiv:1405.0790[hep-th]], special field-dependent BRST-antiBRST transformations with functionally-dependent parameters $λ_{a}=\int dt\(s_{a}Λ) $, generated by a finite even-valued function $Λ(t)$ and by the anticommuting generators $s_{a}$ of BRST-antiBRST transformations, amount to a precise change of the gauge-fixing function for arbitrary constrained dynamical systems. This proves the independence of the vacuum functional under such transformations. We derive a new form of the Ward identities, depending on the parameters $λ_{a}$, and study the problem of gauge-dependence. We present the form of transformation parameters which generates a change of the gauge in the Hamiltonian path integral, evaluate it explicitly for connecting two arbitrary $R_ξ$-like gauges in the Yang--Mills theory and establish, after integration over momenta, a coincidence with the Lagrangian path integral [arXiv:1405.0790[hep-th]], which justifies the unitarity of the $S$-matrix in the Lagrangian approach.
