description: We perform a systematic study of radiative corrections to the masses of the Higgs bosons in the minimal supersymmetric standard model (MSSM) augmented by a single gauge singlet, the so-called next-to-minimal supersymmetric standard model (NMSSM). Our method is based on the one-loop effective potential and includes effects of top quark, squark, Higgs and Higgsino loops. We discuss the renormalisation group flows of Yukawa couplings and the upper bound on the lightest CP-even neutral Higgs boson mass as a function of the heavier stop mass and top mass. We then give a general discussion of Higgs boson phenomenology including radiative corrections. We survey as much of the parameter space of the Higgs sector of the NMSSM as is practicable, and analyse the full spectrum of Higgs masses and couplings in these regions of parameter space. Characteristic signatures of the NMSSM such as light charged bosons and weakly coupled neutral scalars are discussed, as are the relative sizes of the various radiative corrections. The MSSM is also discussed as a limiting case of the NMSSM for comparison.

Missionary life writing: Constructing a self – denied
Creators: name: Brooks, Mary
Publisher: name: Australian Catholic University
Year: 2018

description: This research investigates the writing of British-dominion missionaries working in China during the period 1860 to 1920 – a period of great intensity for mission activity, and prolonged turbulence and humiliation for the Chinese Empire. The Protestant missionary enterprise was referred to as a “writing machine” for its production of literature in the nineteenth and early twentieth centuries, relying upon regular accounts from missionaries for publication, designed to inform, inspire and perpetuate mission funding. In the wake of Edward Said’s foundational work Orientalism (1978), scholars have sought to investigate the relationship between the textual activity of missionaries, and the formation of thought and attitude in shaping imperial ideology. This project however differs. Departing from a specific focus on empire, here attention is drawn to narratives of self-construction. A central concern has been how missionary texts construct the author as an agent within the missionary process. On the one hand, missionary work is the supreme self-effacement, a call to sacrifice the self in the service of others. The missionary enterprise on the other hand, was contingent upon missionaries’ life writing for success. The self-effacement of the missionary subsumed within the sacrificial act runs counter to the self-promoting concepts of the mission enterprise. This study investigates dissonant elements that result from such a paradox and examines ways in which missionary writing constructs the authorial persona as it responds to the challenges of missionary work. While this project sits within mission and life writing studies, it draws upon historical and literary analysis to investigate the complex ways in which vocationally-called individuals negotiate narratives of self under alienating circumstances.

description: The Tuscan Lifestyles case (Mason 2003) offers a simple twist on the standard view of how to value a newly acquired customer, highlighting how standard retention-based approaches to the calculation of expected CLV are not applicable in a noncontractual setting. Using the data presented in the case (a series of annual histograms showing the aggregate distribution of purchases for two different cohorts of customers newly “acquired” by a catalog marketer), it is a simple exercise to compute an estimate of “expected five-year CLV”. If we wish to arrive at an estimate of CLV that includes the customer’s “life” beyond five years or are interested in, say, sorting out the purchasing process (while “alive”) from the attrition process, we need to use a formal model of buying behavior that can be applied on such coarse data. To tackle this problem, we utilize the Pareto/NBD model developed by Schmittlein, Morrison and Colombo (1987). However, existing analytical results do not allow us to estimate the model parameters using the data summaries presented in the case. We therefore derive an expression that enables us to do this. The resulting parameter estimates and subsequent calculations offer useful insights that could not have been obtained without the formal model. For instance, we were able to decompose the lifetime value into four factors, namely purchasing while active, dropout, surge in sales in the first year and monetary value of the average purchase. We observed a kind of “triple jeopardy” in that the more valuable cohort proved to be better on the three most critical factors.

description: We consider electro-weak Higgs plus three jets production at NLO QCD beyond strict VBF acceptance cuts. We investigate, for the first time, how accurate the VBF approximation is in these regions and within perturbative uncertainties, by a detailed comparison of full and approximate calculations. We find that a rapidity gap between the tagging jets guarantees a good approximation, while an invariant mass cut alone is not sufficient, which needs to be confronted with experimental choices. We also find that a significant part of the QCD corrections can be attributed to Higgs-Strahlungs-type topologies.

description: We study sequential programs that are instruction sequences with jump-shift instructions in the setting of PGA (ProGram Algebra). Jump-shift instructions preceding a jump instruction increase the position to jump to. The jump-shift instruction is not found in programming practice. Its merit is that the expressive power of PGA extended with the jump-shift instruction, is not reduced if the reach of jump instructions is bounded. This is used to show that there exists a finite-state execution mechanism that by making use of a counter can produce each finite-state thread from some program that is a finite or periodic infinite sequence of instructions from a finite set.

description: This paper formulates and estimates a dynamic model of labor supply, occupational sorting, human capital accumulation and discrimination to explain the narrowing gender earnings gap from 1968 to 1993. The paper proves the model is identified and develops a three-step estimation technique. Imperfect information significantly amplifies exogenous shocks: statistical discrimination accounts for 36 percent of the observed gender earnings gap in the mid-to-late 1970s, declining to 22 percent in the mid-to-late 1980s. Gender differences in preferences are comparatively less important: the gap would have been at least 56 percent smaller in the mid-to-late 1970s and would have nearly closed by the mid-to-late 1980s if it was driven only by preference. Increases in overall productivity and demographic changes account for a large percentage of the decline in the gender earnings gap and the increase in female labor market experience, while a relative increase in productivity raises women's representation in professional occupations.

description: Reactive synthesis for the GR(1) fragment of LTL has been implemented and studied in many works. In this workshop paper we present and evaluate a list of heuristics to potentially reduce running times for GR(1) synthesis and related algorithms. The list includes early detection of fixed-points and unrealizability, fixed-point recycling, and heuristics for unrealizable core computations. We evaluate the presented heuristics on SYNTECH15, a total of 78 specifications of 6 autonomous Lego robots, written by 3rd year undergraduate computer science students in a project class we have taught, as well as on several benchmarks from the literature. The evaluation investigates not only the potential of the suggested heuristics to improve computation times, but also the difference between existing benchmarks and the robot's specifications in terms of the effectiveness of the heuristics.

description: We investigate gravitino dark matter scenarios in which the primordial ^6Li production is catalyzed by bound-state formation of long-lived negatively charged particles X^- with ^4He. In the constrained minimal supersymmetric Standard Model (CMSSM) with the stau^- as the X^-, the observationally inferred bound on the primordial ^6Li abundance allows us to derive a rigid lower limit on the gaugino mass parameter for a standard cosmological history. This limit can have severe implications for supersymmetry searches at the Large Hadron Collider and for the reheating temperature after inflation.

description: The relationship between cost and output has been investigated intensively by economists. In addition to the development of elaborate theoretical models, a vast number of empirical cost studies have been undertaken for different types of firms, ranging from farms to electrical utilities. With the rapid increase in hospital costs, it seems natural that economists would apply their statistical techniques to gain insights into some of the patterns of cost increases and reasons for the rise.

description: We present an analysis of the quantum fluctuations around the electroweak sphaleron and calculate the associated determinant which gives the 1--loop correction to the sphaleron transition rate. The calculation differs in various technical aspects from a previous analysis by Carson et al. so that it can be considered as independent. The numerical results differ also -- by several orders of magnitude -- from those of this previous analysis; we find that the sphaleron transition rate is much less suppressed than found previously.

description: We provide a pedagogical review on the calculation of highly excited eigenstates of disordered interacting quantum systems which can undergo a many-body localization (MBL) transition, using shift-invert exact diagonalization. We also provide an example code at https://bitbucket.org/dluitz/sinvert_mbl/. Through a detailed analysis of the simulational parameters of the random field Heisenberg spin chain, we provide a practical guide on how to perform efficient computations. We present data for mid-spectrum eigenstates of spin chains of sizes up to $L=26$. This work is also geared towards readers with interest in efficiency of parallel sparse linear algebra techniques that will find a challenging application in the MBL problem.
E-Stability vis-a-vis Determinacy Results for a Broad Class of Linear Rational Expectations Models

description: It is argued that learnability/E-stability is a necessary condition for a RE solution to be plausible. A class of linear models considered by Evans, G.W. and Honkapohja, S. [2001. Learning and Expectations in Macroeconomics, Princeton University Press.] is shown to include all models of the form used by King, R.G. and Watson, M.W. [1998. The solution of singular linear difference systems under rational expectations. International Economic Review 39, 1015–1026] and Klein, P. [2000. Using the generalized Schur form to solve a multivariate linear rational expectations model. Journal of Economic Dynamics and Control 24, 1405–1423], which permits any number of lags, leads, and lags of leads. For this broad class it is shown that, if current-period information is available in the learning process, determinacy is a sufficient condition for E-stability. It is not a necessary condition, however; there exist cases with more than one stable solution in which the solution based on the decreasing-modulus ordering of the system's eigenvalues is E-stable. If in such a case the other stable solutions are not E-stable, then the condition of indeterminacy may not be crucial for practical issues.

subject: FOS: Health sciences

description: Purpose: We aimed to test the effects of providing municipal support and training to primary health care providers compared to both training alone and to care as usual on the proportion of adult patients having their alcohol consumption measured.
Methods: We undertook a quasi-experimental study reporting on a five-month implementation period in 58 primary health care units from municipal areas within Bogotá (Colombia), Mexico City (Mexico) and Lima (Peru). Within the municipal areas, units were randomized to four arms: (1) care as usual (control); (2) training alone; (3) training and municipal support using a less intensive clinical and training package; and, (4) training and municipal support using a more intense clinical and training package. The primary outcome was the cumulative proportion of consulting adult patients out of the population registered within the unit whose alcohol consumption was measured
(coverage).
Results: The combination of municipal support and training did not result in higher coverage than training alone (negative binomial regression coefficient =-0.12, 95% CI= -0.67 to 0.44). Training alone resulted in higher coverage than no training (coefficient =2.28, 95% CI= 1.32 to 3.24). Coverage did not differ by intensity of the clinical and training package (coefficient = -0.2, 95% CI -0.9 to 0.4).
Conclusions: Training of providers is key to increasing coverage of alcohol measurement amongst primary health care patients. Although municipal support provided no added value, it is too early to conclude this finding since full implementation was shortened due to COVID-19 restrictions.

ionized outflows

description: We present a detailed study of ionized outflows in a large sample of 650 hard X-ray detected AGN. Taking advantage of the legacy value of the BAT AGN Spectroscopic Survey (BASS, DR1), we are able to reveal the faintest wings of the [OIII] emission lines associated with outflows. The sample allows us to derive the incidence of outflows covering a wide range of AGN bolometric luminosity and test how the outflow parameters are related to various AGN power tracers, such as Black Hole Mass, Eddington Ratio, Luminosity. We show how ionized outflows are more frequently found in type 1.9 and type 1 AGN with respect to the low fraction in type 2 AGN. Within such a framework, we demonstrate how type 2 AGN outflows are almost evenly balanced between blue- and red-shifted winds. This, in strong contrast with type 1 and type 1.9 AGN outflows which are almost exclusively blue-shifted. Finally, we prove how the outflow occurrence is driven by the accretion rate, whereas the dependence of outflow properties with respect to the other AGNpower tracers happens to be quite mild.
Erratum: An Approximation Algorithm for Minimum-Cost Vertex-Connectivity Problems

description: There is an error in our paper ``An Approximation Algorithm for Minimum-Cost Vertex- Connectivity Problems'' (Algorithmica (1997), 18:21—43). In that paper we considered the following problem: given an undirected graph and values r ij for each pair of vertices i and j , find a minimum-cost set of edges such that there are r ij vertex-disjoint paths between vertices i and j . We gave approximation algorithms for two special cases of this problem. Our algorithms rely on a primal—dual approach which has led to approximation algorithms for many edge-connectivity problems. The algorithms work in a series of stages; in each stage an augmentation subroutine augments the connectivity of the current solution. The error is in a lemma for the proof of the performance guarantee of the augmentation subroutine. In the case r ij = k for all i,j , we described a polynomial-time algorithm that claimed to output a solution of cost no more than 2 H (k) times optimal, where H = 1 + 1/2 + · · · + 1/n . This result is erroneous. We describe an example where our primal—dual augmentation subroutine, when augmenting a k -vertex connected graph to a (k+1) -vertex connected graph, gives solutions that are a factor Ω(k) away from the minimum. In the case r ij ∈ {0,1,2} for all i,j , we gave a polynomial-time algorithm which outputs a solution of cost no more than three times the optimal. In this case we prove that the statement in the lemma that was erroneous for the k -vertex connected case does hold, and that the algorithm performs as claimed.

description: The formation of a stable ‘amidinium-carboxylate’ salt bridge, even in a competing protic solvent (MeOH), was observed based on the binding experiments of anthracene-based diamidine (1) and dicarboxylic acids. The formation of 1:1 binding complexes of the diamidine 1 and dicarboxylic acids was confirmed by DOSY NMR, ESI-Mass, titration experiments and a single crystal X-ray analysis. Similarly, the formation of the ‘amidinium-phosphonate’ salt bridge in the MeOH solution was also evidenced by the complexation of the diamidine 1 and diphosphonic acids.

description: We report experimental results of nuclear magnetic resonance (NMR) at the La site and nuclear quadrupole resonance (NQR) at the Sb site in the filled skutterudite LaOs$_4$Sb$_{12}$. We found that the nuclear spin-lattice relaxation rate divided by temperature $1/T_1T$ at the La site exhibits a different temperature dependence from that at the Sb site. Although $1/T_1T$ at the Sb site is explained by the Korringa mechanism, $1/T_1T$ at the La site exhibits a broad maximum around 50 K, showing the presence of an additional contribution at the La site. The additional low-lying excitations observed at the La site can be understood with the relaxation from anharmonic phonons due to the rattling motion of the La atoms.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: If new sequential leptons $E^\pm$ and $N^0$ exist, the LEP bound implies $m_E$, $m_N > M_Z/2$. The heaviness of the neutral lepton breaks away from the pattern of the first three generations. The minimal model is to have 4 left-handed lepton doublets and 4 right-handed charged lepton singlets, but only one right-handed neutral lepton singlet. Since in general the 3rd and 4th generation should mix, and since $\vert m_N - m_E\vert$ should not be too large, neither $E$ nor $N$ would be stable, and both tend to decay via the Cabibbo suppressed $E\to ν_τ$ or $N\to τ$ charged currents. This leads to the interesting signature of like-sign $W$ pair production via $E^+N \to \barν_ττ^- W^+W^+$ at the SSC and LHC. The popular seesaw mechanism cannot plausibly accommodate the near masslessness of the light neutrinos and the heaviness of $N^0$ simultaneously. The representation structure poses a difficulty to the traditional approach of $SO(10)$-based grand unified theories. The discovery of such new heavy leptons would thus have rather wide ranging and far reaching implications.

description: We present calculations of secondary electron emission (SEE) yields in tungsten as a function of primary electron energies between 50 eV and 1 keV and incidence angles between 0 and 90°. We conduct a review of the established Monte Carlo methods to simulate multiple electron scattering in solids and select the best suited to study SEE in high-Z metals. We generate secondary electron yield and emission energy functions of the incident energy and angle and fit them to bivariate fitting functions using symbolic regression. We compare the numerical results with experimental data, with good agreement found. Our calculations are the first step towards studying SEE in nanoarchitected surfaces for electric propulsion chamber walls.

Using Raman selection rules, we have probed the superconducting gap in the nodal and antinodal regions. We show that under impurity substitutions, the energy of the antinodal peak detected in the superconducting state is not related to the critical temperature Tc and that signatures of superconductivity disappear in the nodal regions. Our experimental findings advocate in favor of gapless arcs around the nodes. The breakdown of the relationship between the antinodal gap amplitude and Tc is discussed in terms of local superconducting gap and pseudogap.

description: In this work we consider perturbations of homogeneous and hypersurface orthogonal cosmological backgrounds with local rotational symmetry (LRS), using a method based on the 1 + 1 + 2 covariant split of spacetime. The backgrounds, of LRS class II, are characterised by that the vorticity, the twist of the 2-sheets, and the magnetic part of the Weyl tensor all vanish. They include the flat Friedmann universe as a special case. The matter contents of the perturbed spacetimes are given by vorticity-free perfect fluids, but otherwise the perturbations are arbitrary and describe gravitational, shear, and density waves. All the perturbation variables can be given in terms of the time evolution of a set of six harmonic coefficients. This set decouples into one set of four coefficients with the density perturbations acting as source terms, and another set of two coefficients describing damped source-free gravitational waves with odd parity. We also consider the flat Friedmann universe, which~has been considered by several others using the 1 + 3 covariant split, as a check of the isotropic limit. In agreement with earlier results we find a second-order wavelike equation for the magnetic part of the Weyl tensor which decouples from the density gradient for the flat Friedmann universes. Assuming vanishing vector perturbations, including the density gradient, we find a similar equation for the electric part of the Weyl tensor, which was previously unnoticed.

Observed Supersymmetry and Parity Doubling of Excited Hadrons from a Simple Spectrum-Generating Algebra

description: We find remarkable agreement with the observed excitations of hadrons with a simple three parameter mass relation of the SU(3) subgroup of the underlying U(15/30) graded Lie group. The baryons are the appropriate supersymmetric partners of the mesons. An interesting feature, which is a focus of current interest, is that the baryons and isobars show parity doubling. Significantly, the ground state baryons and mesons have no place in the fit, so that the parity doubling is indicated only when excitation energy is available. This has correspondence with the parity doubling seen in recent lattice calculations, when thermal excitation is present. The agreement with experiment is comparable to the semi-relativistic quark model which fits with many force parameters and where the observed parity doubling is accidental. The gross splitting of the levels is the same for the strange and the non-strange sectors, suggesting flavour independence.

description: Some astronomy projects require a blind search through a vast number of hypotheses to detect objects of interest. The number of hypotheses to test can be in the billions. A naive blind search over every single hypothesis would be far too costly computationally. We propose a hierarchical scheme for blind search, using various "resolution" levels. At lower resolution levels, "regions" of interest in the search space are singled out with a low computational cost. These regions are refined at intermediate resolution levels and only the most promising candidates are finally tested at the original fine resolution. The optimal search strategy is found by dynamic programming. We demonstrate the procedure for pulsar search from satellite gamma-ray observations and show that the power of the naive blind search can almost be matched with the hierarchical scheme while reducing the computational burden by more than three orders of magnitude.

Equilibrium Earnings Management, Incentive Contracts, and Accounting Standards

Publisher: name: Carnegie Mellon University

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: In this paper, we model earnings management as a consequence of the interaction among self-interested economic agents -- namely, the managers, the shareholders, and the regulators. In our model, a manager controls a stochastic production technology and makes periodic accounting reports about his or her performance; an owner chooses a compensation contract to induce desirable managerial inputs and reporting choices by the manager; and a regulatory body selects and enforces accounting standards to achieve certain social objectives. We show that various economic trade-offs give rise to endogenous earnings management. Specifically, the owner may reduce agency costs by designing a compensation contract that tolerates some earnings management because such a contract allocates the compensation risk more efficiently. The earnings-management activity produces accounting reports that deviate from those prescribed by accounting standards. Given such reports, the valuation of the firm may be nonlinear and s-shaped, thereby recognizing the manager's reporting incentives. We also explore policy implications, noting that (1) the regulator may find enforcing a zero-tolerance policy -- no earnings management allowed -- economically undesirable; and (2) when selecting the optimal accounting standard, valuation concerns may conflict with stewardship concerns. We conclude that earnings management is better understood in a strategic context that involves various economic trade-offs.

description: In the following text we prove that for finite discrete $X$ with at least two elements and infinite $Γ$, the generalized shift transformation semigroup $({\mathcal S},X^Γ)$ is equicontinuous (resp. has at least an equicontinuous point, is not sensitive) if and only if for all $w\inΓ$, $\{φ(w):σ_φ\in{\mathcal S}\}$ is finite. We continue our study regarding distality and expansivity of $({\mathcal S},X^Γ)$.

description: The Askey-Wilson polynomials are a four-parameter family of orthogonal symmetric Laurent polynomials $R_n[z]$ which are eigenfunctions of a second-order $q$-difference operator $L$, and of a second-order difference operator in the variable $n$ with eigenvalue $z +z^{-1}=2x$. Then $L$ and multiplication by $z+z^{-1}$ generate the Askey-Wilson (Zhedanov) algebra. A nice property of the Askey-Wilson polynomials is that the variables $z$ and $n$ occur in the explicit expression in a similar and to some extent exchangeable way. This property is called duality. It returns in the non-symmetric case and in the underlying algebraic structures: the Askey-Wilson algebra and the double affine Hecke algebra (DAHA). In this paper we follow the degeneration of the Askey-Wilson polynomials until two arrows down and in four different situations: for the orthogonal polynomials themselves, for the degenerate Askey-Wilson algebras, for the non-symmetric polynomials and for the (degenerate) DAHA and its representations.

description: A total of 9128 B-, V-, and Ic-band photometric measurements were acquired for 64 classical Cepheids in 1982-2014. For these stars, 1384 times of maximum light are determined and O-C diagrams constructed based on available photoelectric and CCD observations. The data are used to compute the current ephemerides and the normalized Fourier coefficients (cosine expansion), whose analysis confirmed that all the 64 variables were correctly classified as classical Cepheids.

description: Η μεθοδολογία διαχείρισης έργου είναι ένα σύνολο κατευθυντήριων γραμμών και διαδικασιών που θα βοηθήσουν τους διαχειριστές έργων να οργανώσουν έργα για μέγιστη αποτελεσματικότητα. Ουσιαστικά, είναι μια δομή ή μια λίστα ελέγχου που πρέπει να ακολουθήσετε που βοηθά στην αποτελεσματική διαχείριση της διαδικασίας του έργου. Η διαχείριση έργου (PM) είναι ζωτικής σημασίας για ομάδες και οργανισμούς, αλλά για να είναι πραγματικά αποτελεσματική, είναι ζωτικής σημασίας να διασφαλίσετε ότι οι απαιτήσεις της ομάδας, του έργου, του οργανισμού και των στόχων σας συγκεντρώνονται και αντιστοιχίζονται σωστά στη μεθοδολογία. Τα τελευταία χρόνια, οι οργανισμοί μετατοπίζονται από μια παραδοσιακή στρατηγική καταρράκτη σε μια πιο ευέλικτη προσέγγιση. Ωστόσο, η μεγάλη πλειοψηφία χρησιμοποιεί μια υβριδική στρατηγική που ενοποιεί σχετικά κομμάτια κάθε προσέγγισης. Με τη μηχανική λογισμικού να υπάρχει σε ένα τόσο γρήγορο περιβάλλον, οι παραδοσιακές προσεγγίσεις διαχείρισης έργων δεν είναι πλέον βιώσιμες. Αυτό σημαίνει ότι οι επαγγελματίες πληροφορικής πρέπει να βρουν νέους τρόπους για να χειρίζονται συχνά μεταβαλλόμενες εργασίες ανάπτυξης. Μοιράζοντας αυτήν την ιδέα και εστιάζοντας στις υπάρχουσες τεχνικές σταδιακής ανάπτυξης, δεκαεπτά ειδικοί λογισμικού εισήγαγαν τη φιλοσοφία διαχείρισης έργων Agile το 2001. Οι αρχές της ευέλικτης, γρήγορης και με επίκεντρο τη συνεργασία ανάπτυξης λογισμικού περιγράφονται στο Agile Manifesto. Για χρόνια, οι παραδοσιακές μέθοδοι όπως ο καταρράκτης προσφέρουν μια δομημένη προσέγγιση στη διαχείριση έργων και την ανάπτυξη λογισμικού. Σήμερα, το μοντέλο του καταρράκτη δεν είναι εκτός εικόνας αλλά το πλαίσιο έχει μεγαλώσει πολύ. Η ευέλικτη προσέγγιση διαχείρισης έργων εισήχθη ως ένας τρόπος για να φέρει επανάσταση στην ανάπτυξη λογισμικού, σε άμεση αντίθεση με το πιο δομημένο στυλ καταρράκτη. Στη παρούσα εργασία θα ερευνήσουμε τα βασικά χαρακτηριστικά των ευέλικτων μυθολογιών και τις παραλλαγές μεταξύ των στρατηγικών τους καθώς και θα διερευνήσουμε τις διαφορές μεταξύ μεθοδολογιών διαχείρισης καταρράκτη, ευέλικτου και υβριδικού έργου.

description: We performed photoelectric observations of double-mode Cepheids between March 10, 1999 and April 22, 2004 (JD 2451248–2453118) with the 0.76-m reflector of the South African Astronomical Observatory (SAAO), equipped with a pulse-counting photoelectric photometer. It is a cooled unit that employs a Hamamatsu photomultiplier in conjunction with BV Ic filters of the Kron–Cousins photometric system (Cousins, 1976). A description of the observing techniques can be found in Berdnikov and Turner (2004). Observational uncertainties are close to 0.01 mag in all bands. We have obtained a total of 2902 measurements for 16 double-mode Cepheids, listed in the Table. The phases of the observations were calculated with the elements from GCVS (Samus et al., 2017) for BE Pup and U TrA; from Antipin (1997) for V458 Sct; from Berdnikov (1992) for AX Vel; and from ASAS-3 (Pojmanski, 2002) for the other stars. The star BE Pup was identified as a double-mode Cepheid by Hacke and Richert (1990); the GCVS considers it a doubtful CWB star. For all the listed Cepheids, with the exception of V1048 Cen, the period in the Table is that of the fundamental mode. V1048 Cen pulsates in the first and second overtones, and the period in the Table is that of the first overtone.
