description: Low-loss, high frequency acoustic resonators cooled to millikelvin temperatures are a topic of great interest for application to hybrid quantum systems. When cooled to 20 mK, we show that resonant acoustic phonon modes in a Bulk Acoustic Wave (BAW) quartz resonator demonstrate exceptionally low loss (with $Q$-factors of order billions) at frequencies of 15.6 and 65.4 MHz, with a maximum $f.Q$ product of 7.8$\times10^{16}$ Hz. Given this result, we show that the $Q$-factor in such devices near the quantum ground state can be four orders of magnitude better than previously attained. Such resonators possess the low losses crucial for electromagnetic cooling to the phonon ground state, and the possibility of long coherence and interaction times of a few seconds, allowing multiple quantum gate operations.

description: BACKGROUND: Studies in male combat veterans have suggested posttraumatic stress disorder (PTSD) is associated with shorter telomere length (TL). We examined the cross-sectional association of PTSD with TL in women exposed to traumas common in civilian life. METHODS: Data are from a substudy of the Nurses' Health Study II (N = 116). PTSD and subclinical PTSD were assessed in trauma-exposed women using diagnostic interviews. An array of health behaviors and conditions were assessed. DNA was extracted from peripheral blood leukocytes (collected 1996-1999). Telomere repeat copy number to single gene copy number (T/S) was determined by quantitative real-time PCR telomere assay. We used linear regression models to assess associations and examine whether a range of important health behaviors (e.g., cigarette smoking) and medical conditions (e.g., hypertension) previously associated with TL might explain a PTSD-TL association. We further examined whether type of trauma exposure (e.g., interpersonal violence) was associated with TL and whether trauma type might explain a PTSD-TL association. RESULTS: Relative to not having PTSD, women with a PTSD diagnosis had shorter log-transformed TL (β = -.112, 95% confidence interval (CI) = -0.196, -0.028). Adjustment for health behaviors and medical conditions did not attenuate this association. Trauma type was not associated with TL and did not account for the association of PTSD with TL. CONCLUSIONS: Our results add to growing evidence that PTSD may be associated with more rapid cellular aging as measured by telomere erosion. Moreover, the association could not be explained by health behaviors and medical conditions assessed in this study, nor by type of trauma exposure.

description: No abstracts are to be cited without prior reference to the author.The Water Framework Directive (WFD) has developed several methods to assess the benthic status of European marine waters. WFD implementation requires the intercalibration of such methods, in order to ensure that the status classification is consistent and comparable across countries and water body types. A working group of nine countries (Portugal, Spain, France, Belgium, the Netherlands, Germany, Sweden, Ireland, and the UK) has been established to intercalibrate methods in transitional (estuaries) waters, within the Northeast Atlantic ecoregion. The following steps for intercalibration were agreed upon by this group: (i) to establish common water body types across Europe, based on salinity, tidal range, mixing conditions, intertidal area, and estuary size (six common types were identified); (ii) to compile a common dataset (9337 samples collated, from 59 estuaries and 8 countries, covering 5 out of the 6 types, and most of the ecotopes); (iii) to harmonize the taxonomy of the dataset (using ERMS, WoRMS and Fauna Europaea); (iv) to collate human pressures from each estuary; (v) to set reference conditions for each type; (vi) to calculate ecological quality ratios for each of the 10 methods proposed for intercalibration (BAT, M-AMBI, BOPA, BO2A, QSB, MISS, BEQI, AETV, BQI, IQI); (vii) to interpret the response of these methods to different anthropogenic pressures; (viii) to determine boundaries for each of the five quality classes (from bad to high status), using the 10 methods; and (ix) final agreement in the assessment and intercalibration. This contribution presents the steps already taken and the way forward in this intercalibration exercise.

Subjects: subject: 530 Physics

description: Accelerator neutrino oscillation experiments provide a sensitive way to investigate a number of major open questions in neutrino physics. To achieve precision neutrino oscillation measurements, we need a good understanding of key aspects of the experiments, such as the detection technologies used and neutrino interactions at few-GeV energies. The MicroBooNE experiment has advanced the development of technologies for LArTPCs. An ultra-violet laser system was introduced to MicroBooNE in order to measure the electric field in situ, which plays a central role in the formation of charge and light signals in LArTPCs. This thesis describes the setup and operation of the laser system. I developed a general methodology to measure the electric field and the consequent spatial distortion in LArTPCs, which supports precision measurements in accelerator neutrino oscillation experiments. In MicroBooNE, the measured electric field distortions are up to 15 ± 3% with respect to the nominal value, and the measured spatial distortions are up to 15 ± 3 cm. The result of the electric field measurement is applied to the detector simulation and the event reconstruction, which leads to a better detector characterization for neutrino analyses. A significant concern for measurements of neutrino interactions is model dependence, as the currently available models are not sufficient for describing the picture of neutrino interacting at few-GeV energies. In this thesis, I developed a detailed strategy for a model-independent cross-section measurement at low energy transfers, where the available model predictions do not agree with the inclusive measurements from multiple experiments. A likelihood fit technique for cross-section extraction is realized in an accelerator neutrino experiment using a LArTPC for the first time. The treatment of systematic uncertainties developed in this thesis is generally applicable for analyses using similar fitting techniques. This neutrino interaction study at low energy transfers provides a probe to the poorly understood region of neutrino cross sections. The measurement scheme developed here aims to guide future model-independent cross-section measurements, particularly for neutrino experiments using LArTPCs.

description: Atmospheric emission is a dominant source of disturbance in ground-based astronomy at mm wavelengths. The Antarctic plateau is recognized to be an ideal site for mm and sub-mm observations, and the French/Italian base of Dome C is among the best sites on Earth for these observations. In this paper we present measurements, performed using the BRAIN-pathfinder experiment, at Dome C of the atmospheric emission in intensity and polarization at 150GHz, one of the best observational frequencies for CMB observations when considering cosmic signal intensity, atmospheric transmission, detectors sensitivity, and foreground removal. Careful characterization of the air-mass synchronous emission has been performed, acquiring more that 380 elevation scans (i.e. "skydip") during the third BRAIN-pathfinder summer campaign in December 2009/January 2010. The extremely high transparency of the Antarctic atmosphere over Dome Concordia is proven by the very low measured optical depth: =0.050 \pm 0.003 \pm 0.011 where the first error is statistical and the second is systematic error. Mid term stability, over the summer campaign, of the atmosphere emission has also been studied. Adapting the radiative transfer atmosphere emission model "am" to the particular conditions found at Dome C, we also infer the level of the PWV content of the atmosphere, notoriously the main source of disturbance in millimetric astronomy (=0.77 +/- 0.06 + 0.15 - 0.12 mm). Upper limits on the air-mass correlated polarized signal are also placed for the first time. The degree of circular polarization of atmospheric emission is found to be lower than 0.2% (95%CL), while the degree of linear polarization is found to be lower than 0.1% (95%CL). These limits include signal-correlated instrumental spurious polarization.

description: The signalling pathways that maintain primed human pluripotent stem cells (hPSCs) have been well characterised, revealing a critical role for TGFβ/Activin/Nodal signalling. In contrast, the signalling requirements of naive human pluripotency have not been fully established. Here, we demonstrate that TGFβ signalling is required to maintain naive hPSCs. The downstream effector proteins - SMAD2/3 - bind common sites in naive and primed hPSCs, including shared pluripotency genes. In naive hPSCs, SMAD2/3 additionally bind to active regulatory regions near to naive pluripotency genes. Inhibiting TGFβ signalling in naive hPSCs causes the downregulation of SMAD2/3-target genes and pluripotency exit. Single-cell analyses reveal that naive and primed hPSCs follow different transcriptional trajectories after inhibition of TGFβ signalling. Primed hPSCs differentiate into neuroectoderm cells, whereas naive hPSCs transition into trophectoderm. These results establish that there is a continuum for TGFβ pathway function in human pluripotency spanning a developmental window from naive to primed states.

description: No abstracts are to be cited without prior reference to the author.Initially described in 2000, AZTI’s Marine Biotic Index (AMBI) aims to assess alterations in communities of soft-bottom marine benthic macroinvertebrates caused by anthropogenic impacts. Although it was designed to be used in European estuaries and coasts, this index, based on Pearson and Rosenberg’s model of responses to organic enrichment, is being used successfully worldwide. Species are assigned to one of five ecological groups (from sensitive to first-order opportunistic species). Abundances of each species are used to calculate the relative proportions of individuals in each sample belonging to each group, and these are used to calculate the index. The index takes a continuous value, between 0 and 6 (from undisturbed to heavily disturbed communities), keeping 7 for azoic sediments (extremely disturbed). AMBI is being used extensively in the ecological status classification within the European Water Framework Directive, forming part of several multimetric and multivariate methods. Taking into account statistical difficulties associated with the use of raw abundance data, modifications to the index were recently proposed. These were to transform abundances prior to its calculation, or to use data other than abundances, which might be more functionally relevant (such as biomass or production data). Using data from the Basque coast and estuaries (northern Spain) collected between 1995 and 2009, where the evolution of human pressures and restoration actions in the area may be taken into account, the performance of AMBI is compared with that of the proposed modifications in order to assess their usefulness.

"It's really shaped who I am" : identity in hearing siblings of deaf adults
Creators: name: Yeo, Siou Shien
Publisher: name: University of British Columbia
Year: 2012

description: In the past few decades, there has been a surge of interest in the experiences and perspectives of siblings. The sibling relationship has come under scrutiny for its impact on life quality, life trajectory, and self-identity. Although interest in the perspectives of siblings has flourished, there continues to be a dearth of research on hearing siblings of deaf persons. This qualitative study seeks to help fill this gap by exploring the stories of hearing siblings of deaf persons in a retrospective. The overarching question that guided this study was, “How do hearing siblings of deaf persons navigate their identities?” Semi-structured interviews were conducted with six hearing adult siblings of deaf persons. Questions were asked regarding the experiences of growing up with a deaf sibling, family life, and impact on life trajectory. A narrative analysis using the categorical-content perspective (Lieblich, Tuval-Mashiach, & Zilber, 1998) yielded an overarching theme of sameness versus difference, with four subthemes of 1) differential treatment 2) sibling de-identification 3) the (un)luck of the draw, and 4) boundaries. Participants navigated their identities through these concepts, articulating an understanding of the positioning of themselves and their siblings. All the stories told revealed that the sibling relationship has had a significant impact on participants' life trajectories and sense of self.

description: The single most valuable source of information for understanding Egypt’s administration of its northern empire during the Amarna period is a corpus of roughly 350 cuneiform tablets, known collectively as the “Amarna letters.” These documents, which come mostly from an archive found at Tell el-Amarna in the 1880s, were exchanged between the Egyptian court and Near Eastern rulers of polities both large and small. Although the chronology is still debated, the letters are thought to span a period of at most three decades in the latter half of the fourteenth century b.c.—between the 32nd year of Amenhotep III and the 4th year of Tutankhamun.1

While certain aspects of these letters have been extensively studied, their potential to illuminate the internal structure of the empire at this time has by no means been exhausted. As I hope to demonstrate herein, the results of a systematic study of the greeting formulas used by Egypt’s vassals when addressing the pharaoh can reveal a great deal about the varying degrees of political control within the Egyptian empire. After a brief description of the methodology employed in this study, I will discuss the clustering in social rank that I believe is discernible among the different geographic areas of Egypt’s northern empire. Whether these proposed rankings may potentially shed light on the preparation of individual treaties between the Egyptian state and particular vassals is the subject of the concluding section of this article.

description: Following our paper [J. Math. Phys. 50 (2009) 123102], we systematically carry out Lie symmetry analysis for the barotropic vorticity equation on the rotating sphere. All finite-dimensional subalgebras of the corresponding maximal Lie invariance algebra, which is infinite-dimensional, are classified. Appropriate subalgebras are then used to exhaustively determine Lie reductions of the equation under consideration. The relevance of the constructed exact solutions for the description of real-world physical processes is discussed. It is shown that the results of the above paper are directly related to the results of the recent letter by N. H. Ibragimov and R. N. Ibragimov [Phys. Lett. A 375 (2011) 3858] in which Lie symmetries and some exact solutions of the nonlinear Euler equations for an atmospheric layer in spherical geometry were determined.

description: We study the relationship between microscopic structure and viscosity in non-Brownian suspensions. We argue that the formation and opening of contacts between particles in flow effectively leads to a negative selection of the contacts carrying weak forces. We show that an analytically tractable model capturing this negative selection correctly reproduces scaling properties of flows near the jamming transition. In particular, we predict that (i) the viscosity η diverges with the coordination z as η ~ (z_c-z)^{-(3+θ)/(1+θ)}, (ii) the operator that governs flow displays a low-frequency mode that controls the divergence of viscosity, at a frequency ω_min\sim(z_c-z)^{(3+θ)/(2+2θ)}, and (iii) the distribution of forces displays a scale f* that vanishes near jamming as f*/\sim(z_c-z)^{1/(1+θ)} where θ characterizes the distribution of contact forces P(f)\simf^θ at jamming, and where z_c is the Maxwell threshold for rigidity.

description: The construction of the conformal scalar propagator which has been obtained in the preceding two projects as an analytic function of the Schwarzschild black-hole space-time is completed with a boundary condition imposed by the physical context through contour integration in the exterior vicinity of the event horizon. It is shown that, as a consequence of the semi-classical character which the emitted quanta have in that exterior vicinity, the particle production by the Schwarzschild black hole which was formally established in the preceding project is identical to thermal Hawking radiation. By extension, it is established that such a particle production corresponds to a spectrum which detracts from thermality by the amount predicted by Parikh and Wilczek if energy conservation is properly imposed as a constraint on scalar propagation. The results obtained herein support the case made by S. Hawking on the relation between quantum propagation and observation of particles produced by a black hole.

description: No abstracts are to be cited without prior reference to the author.The European Water Framework Directive (WFD; 2000/60/EG) and the European Marine Strategy Framework Directive (MSFD; 2008/56/EC) were umbrella legislations for fresh and marine waters. It is a challenge for the scientific community to translate the principles of these directives into realistic and accurate approaches. Both directives have common principles, although these were tackled differently. The WFD was executed during the last decade, and many results from it have already been published. The process delivered valuable knowledge of which the implementation of the MSFD could be founded. The ICES Benthos Ecology Working Group aimed to compile the lessons learned from the application of benthic indicators in the WFD implemented within the MSFD through the description of (i) how the principles are theoretically filled in by both directives, (ii) how the process is tackled in the WFD process, and (iii) what these insights might mean for the implementation of the MSFD. A first main principle is the realization of the ecosystem approach. Second, the comparability of benthic indicators, class boundary settings and the relationships between indicators and anthropogenic pressures are highlighted. Third, some aspects related to the monitoring requirements of both directives are discussed. We conclude that testing and integration of the different approaches was facilitated during the WFD process and led to further insights and improvements. This facilitated the selection of the most accurate approach for each purpose (principle, region, water type, etc.). Expert involvement in the entire process proved to be of vital importance.

description: Measuring the total charm cross section is important for the comparison to theoretical predictions of the highest precision available for charm today, which are completely known up to NNLO QCD for the total inclusive cross sections. These are also independent of charm fragmentation, while practical measurements of charm hadrons in a fiducial phase space are not. Recently the LHC experiments have reported non-universality of charm fragmentation, which shows that e.g. charm baryon-to-meson ratios are not universal in different collision systems, and that the related production fractions also depend on transverse momentum. This breaks the charm fragmentation universality that was assumed until recently for the extrapolation of experimental measurements to the full total charm cross section phase space. A proposal is made how to address this non-universality in a data driven way without the need to implement any particular non-universal fragmentation model. As a practical example, this method is applied to the extrapolation of published LHC measurements of $D^0$ production at $\sqrt{s}=5$ TeV to the corresponding total charm cross section, which fully accounts for charm fragmentation non-universality for the first time. The result, $8.43 ^{+1.05}_{-1.16}(\text{total})$ mb, differs substantially from the one assuming charm fragmentation universality, but still compares well to theoretical QCD predictions up to NNLO.
title: "Undisabled by Covid": Reflections of a (usually disabled) socio-legal scholar (accepted)
Creators: name: Williams, Clare

description: We have all been disabled by Covid; routines interrupted, interactions curtailed, access denied. For many, this was a new and troubling form of existence. For some though, like me, this was normal life. As a socio-legal scholar who uses a wheelchair full time, exclusion from academic spaces, and the interactions that went on in those spaces, was the norm. And then Covid arrived. Lockdowns made working and socialising from home mandatory, and in the process, disabled the rest of society overnight. This had the ironic impact of levelling the playing field for those of us accustomed to exclusion by the built environment. This paper recounts my lived experiences of lockdown, and explores the results for those with physical impairments of the massive social experiment into virtual and hybrid working that was necessitated by the pandemic. It argues that by focusing on individual choice to determine future hybrid working arrangements, when for many that choice is not freely made, we risk further entrenching disadvantage. In the context of higher education and research, the result is the full realisation of the neoliberal academy in which scholars with disabilities are blamed for their own self-exclusion.

description: No abstracts are to be cited without prior reference to the author.Oxygen-depleted areas are the most severe manifestation of ecosystem degradation in shallow coastal waters. Today, nearly 415 eutrophic and hypoxic coastal systems have been identified worldwide. “Dead zones” cause cascading effects ranging from the molecular to the ecosystem level. Ultimately, biodiversity loss and disrupted ecosystem function (e.g. filter- and suspension-feeding capacity, bioturbation) can change structurally complex and diverse benthic communities into far simpler, impoverished ones. Biological indicators, in particular the use of benthic species, are a developing field in these efforts. This calls for the identification of potential indicator species for various levels of impact. The northern Adriatic is a recognized key area for seasonal low dissolved oxygen events. The onset and extent of catastrophic events, however, is difficult to predict, hindering full documentation in the field. Using a specially developed underwater chamber, we experimentally recreate small-scale anoxias in a community setting. The in situ experiments successfully mimic full-scale hypoxia/anoxia and reveal a clear sequence of species-specific macrobenthic behaviours and mortalities correlated to specific thresholds. This yield of new details (e.g. predator–prey interactions), at a finer, more nuanced scale of resolution than ever before in the field, is a step forward in compiling a broadly applicable catalogue of behaviours, a list of sensitive/tolerant species, and a range of community compositions to determine in situ ecosystem status and stability. This will also help retrospectively pinpoint past anoxias and predict future community compositions. The results provide crucial input for coastal management, which is called upon to reduce additional anthropogenic pressures (e.g. benthic trawling) during critical phases.

description: The ferrimagnetic spin-1/2 chain composed of alternating Ising and Heisenberg spins in an arbitrarily oriented magnetic field is exactly solved using the spin-rotation transformation and the transfer-matrix method. It is shown that the low-temperature magnetization process depends basically on a spatial orientation of the magnetic field. A sharp stepwise magnetization curve with a marked intermediate plateau, which emerges for the magnetic field applied along the easy-axis direction of the Ising spins, becomes smoother and the intermediate plateau shrinks if the external field is tilted from the easy-axis direction. The magnetization curve of a polycrystalline system is also calculated by performing powder averaging of the derived magnetization formula. The proposed spin-chain model brings an insight into high-field magnetization data of 3d-4f bimetallic polymeric compound Dy(NO_3)(DMSO)_2Cu(opba)(DMSO)_2, which provides an interesting experimental realization of the ferrimagnetic chain composed of two different but regularly alternating spin-1/2 magnetic ions Dy^{3+} and Cu^{2+} that are reasonably approximated by the notion of Ising and Heisenberg spins, respectively.

description: We report an unusual giant linear magnetostrictive effect in the ferrimagnet Gd$_{2/3}$Ca$_{1/3}$MnO$_3$ ($T_{c} \approx$80 K). Remarkably, the magnetostriction, negative at high temperature ($T \approx T_{c}$), becomes positive below 15 K when the magnetization of the Gd sublattice overcomes the magnetization of the Mn sublattice. A rather simple model where the magnetic energy competes against the elastic energy gives a good account of the observed results and confirms that Gd plays a crucial role in this unusual observation. Unlike previous works in manganites where only striction associated with 3$d$ Mn orbitals is considered, our results show that the lanthanide 4$f$ orbitals related striction can be very important too and it cannot be disregarded.

Funeral rites and ceremonies

description: Of all political rituals enacted in a kingdom, coronations and funerals are typically among the most lavish and highly ritualized. At these two critical junctures, the paradox of the mortality of the body natural and the immortality of the body politic must be faced, reconciled, and triumphed over if order is to return to society. If the death of a ruler marks a reoccurring and unavoidable cyclical crisis in the life cycle of any state, there are two instances in which it is possible to envision this crisis ratcheted up significantly. The first is when the death of a ruler occurs at a particularly unstable period in that state's history. In the highly influential edited volume Rituals of Royalty, Averil Cameron and Amélie Kuhrt postulate an inverse correlation (in certain societies at certain times) between pomp and pageantry, on the one hand, and political power and stability on the other. In Babylon, in Byzantium, and in many other states besides, they suggest that rulers amplify the appearance of power in order to convince others of the reality of that vision. This tactic is, in their view, the political equivalent of sympathetic magic, and the extravagant rituals designed to showcase an absolute power that constituted more of a goal than a reality represent the last-ditch acts of threatened monarchs. Much the same strategizing, however, should also be expected when the state is new and is not yet an accepted part of the natural order of things.

In First Dynasty Egypt, the locus of this case study in royal funerary ritual, the effects of the state are starkly visible in the archaeological record. The monarchs of the First Dynasty were engaged in the project of trying to naturalize something that was at that point decidedly unnatural. At the same time, royal iconography equating the king with the falcon god Horus suggests that these individuals were actively promoting the ideology that the head of state was a deity incarnate. For all these reasons, and for undoubtedly many more besides, one can hardly imagine an ideological performance that would have been more carefully scripted or more highly charged than a royal funeral in First Dynasty Egypt.

description: Theory of spin-orbit coupling in bilayer graphene is presented. The electronic band structure of the AB bilayer in the presence of spin-orbit coupling and a transverse electric field is calculated from first-principles using the linearized augmented plane wave method implemented in the WIEN2k code. The first-principles results around the K points are fitted to a tight-binding model. The main conclusion is that the spin-orbit effects in bilayer graphene derive essentially from the single-layer spin-orbit coupling which comes almost solely from the d orbitals. The intrinsic spin-orbit splitting (anticrossing) around the K points is about 24μeV for the low-energy valence and conduction bands, which are closest to the Fermi level, similarly as in the single layer graphene. An applied transverse electric field breaks space inversion symmetry and leads to an extrinsic (also called Bychkov-Rashba) spin-orbit splitting. This splitting is usually linearly proportional to the electric field. The peculiarity of graphene bilayer is that the low-energy bands remain split by 24μeV independently of the applied external field. The electric field, instead, opens a semiconducting band gap separating these low-energy bands. The remaining two high-energy bands are spin-split in proportion to the electric field; the proportionality coefficient is given by the second intrinsic spin-orbit coupling, whose value is 20μeV. All the band-structure effects and their spin splittings can be explained by our tight-binding model, in which the spin-orbit Hamiltonian is derived from symmetry considerations. The magnitudes of intra- and interlayer couplings---their values are similar to the single-layer graphene ones---are determined by fitting to first-principles results.

description: A survey of office workers at four sites was conducted by Columbia University School of Public Health during 1981 and 1982 to explore relationships between office working conditions and employee health. Walk through surveys of each site were conducted by the research team with joint labor-management sponsorship. A total of 2074 non-managerial office workers filled out a 30-minute self-administered survey at their respective workplaces. Multiple item scales were tested and constructed to measure indoor air quality and ergonomic factors. Significant differences in ergonomic conditions and air quality between the sites were observed. These differences corresponded with researcher observations prior to the surveys. Significant associations between the reported air quality and respiratory symptoms and between ergonomic factors and musculoskeletal symptoms were found. Specificity of the relationship between reports about the environment and health symptoms was demonstrated. The implications of this approach for industrial hygiene investigations of non-industrial environments are discussed.

Although these constructions are attested from Old High German to the 19th century, we focus on the Middle High German period. Our arguments are based upon information- and discourse-structural properties. These clauses share typical properties of V1 clauses, namely, the absence of a topic-comment division, their relevance for textual cohesion, the accessibility status of the subject, the lexical semantics of their predicate, and their expressivity.*
Zero range potential for particles interacting via Coulomb potential: application to electron positron annihilation

description: The zero range potential is constructed for a system of two particles interacting via the Coulomb potential. The singular part of the asymptote of the wave function at the origin which is caused by the common effect of the zero range potential singularity and of the Coulomb potential is explicitly calculated by using the Lippmann-Schwinger type integral equation. The singular pseudo potential is constructed from the requirement that it enforces the solution to the Coulomb Schrödinger equation to possess the calculated asymptotic behavior at the origin. This pseudo potential is then used for constructing a model of the imaginary absorbing potential which allows to treat the annihilation process in positron electron collisions on the basis of the non relativistic Schrödinger equation. The functional form of the pseudo potential constructed in this paper is analogous to the well known Fermi-Breit-Huang pseudo potential. The generalization of the optical theorem on the case of the imaginary absorbing potential in presence of the Coulomb force is given in terms of the partial wave series.
