description: Despite the rapid expansion of U.S.-China trade ties, the increase in U.S. FDI in China, and the expanding amount of economic research exploring these developments, a number of misconceptions distort the popular understanding of U.S. multinationals in China. In this paper, we seek to correct four common misunderstandings by providing a statistical portrait of several aspects of U.S. affiliate activity in the country and placing this activity in its appropriate economic context.
Anomalous impurity effect on magnetization in frustrated one-dimensional ferro- and ferrimagnets

description: Significant decrease of spontaneous magnetization in frustrated one-dimensional ferro- and ferrimagnets due to non-magnetic impurities is predicted. Using the density-matrix renormalization group method and the exact diagonalization method, we confirm that the total spin can vanish due to a single impurity in finite chains. Introducing the picture of magnetic domain inversion, we numerically investigate the impurity-density dependence of magnetization. In particular, we show that even with an infinitesimal density of impurities the magnetization in the ground state is reduced by about 40% from that of the corresponding pure system. Conditions for the materials which may show this anomalous impurity effect are formulated.

description: Local observations indicate that climate change and shifting disturbance regimes are causing permafrost degradation. However, the occurrence and distribution of permafrost region disturbances (PRDs) remain poorly resolved across the Arctic and Subarctic. Here we quantify the abundance and distribution of three primary PRDs using time-series analysis of 30-m resolution Landsat imagery from 1999 to 2014. Our dataset spans four continental-scale transects in North America and Eurasia, covering ~10% of the permafrost region. Lake area loss (−1.45%) dominated the study domain with enhanced losses occurring at the boundary between discontinuous and continuous permafrost regions. Fires were the most extensive PRD across boreal regions (6.59%), but in tundra regions (0.63%) limited to Alaska. Retrogressive thaw slumps were abundant but highly localized (<10−5%). Our analysis synergizes the global-scale importance of PRDs. The findings highlight the need to include PRDs in next-generation land surface models to project the permafrost carbon feedback.

description: La novela decimonónica, con su énfasis en el detalle realista y naturalista, se perfila como el modelo literario ideal para constatar las transformaciones sociales, políticas y económicas que marcaron esta época. En 1870, Benito Pérez Galdós delineaba los cambios que se estaban produciendo en la sociedad, a la vez que proponía una modificación de la escritura novelesca en España. Galdós percibió un proceso paralelo en la progresiva adaptación y desaparición de la aristocracia y el auge de la clase media, considerando que en esta última se halla la “base del orden social” (“Observaciones” 130). Bajo la perspectiva galdosiana, este reencontrado equilibrio social, que se concentra simbólicamente en la estructura de la familia, está amenazado de forma binaria por el “vicio” del adulterio y el “vicio de la presunción” (135). Las novelas del siglo XIX arrojan luz sobre las familias que se verán afectadas y transformadas, por un lado, por el deseo erótico y, por otro, por el anhelo materialista a los que Galdós hace referencia.

description: We show that $\N=1$ gauge theories with an adjoint chiral multiplet admit a wide class of large-N double-scaling limits where $N$ is taken to infinity in a way coordinated with a tuning of the bare superpotential. The tuning is such that the theory is near an Argyres-Douglas-type singularity where a set of non-local dibaryons becomes massless in conjunction with a set of confining strings becoming tensionless. The doubly-scaled theory consists of two decoupled sectors, one whose spectrum and interactions follow the usual large-N scaling whilst the other has light states of fixed mass in the large-N limit which subvert the usual large-N scaling and lead to an interacting theory in the limit. $F$-term properties of this interacting sector can be calculated using a Dijkgraaf-Vafa matrix model and in this context the double-scaling limit is precisely the kind investigated in the "old matrix model'' to describe two-dimensional gravity coupled to $c<1$ conformal field theories. In particular, the old matrix model double-scaling limit describes a sector of a gauge theory with a mass gap and light meson-like composite states, the approximate Goldstone boson of superconformal invariance, with a mass which is fixed in the double-scaling limit. Consequently, the gravitational $F$-terms in these cases satisfy the string equation of the KdV hierarchy.

description: Otites nubila Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 109.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Italy because the work deals with Italian species.
TYPE MATERIAL: not found in this study.
 CURRENT STATUS: junior synonym of Otites nebulosa (Olivier, 1811) (Soós 1984c: 49).
 REMARKS: Rondani’s (1856: 109) key for the genus Otites Latreille, 1804 lists Otites nubila as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. Rondani (1869a: 12) considered Otites nubila as a junior synonym of Otites bucephala (Meigen, 1830). We were unable to locate any type material of this nominal species in our study. The MZUF does not contain any specimen named Otites nubila but, under the name Otites bucephala, there are six specimens (all non-types): one male, three females and two specimens of undetermined sex. We leave the study of these latter specimens to a future specialist for the recognition of the type series of Otites nubila Rondani, 1856. Evenhuis & Pape (2020) incorrectly considered Otites nubila as a nomen nudum.

description: This thesis describes the development of a sensitive method for the separation and quantitation of organic N-chloramines in chlorinated tap water. 5-Dimethylaminonaphthalene- l-sulfinic acid has been synthesized and characterized. It yields highly fluorescent dansyl derivatives on reaction with N-chloramines. Conditions of the derivatization were optimized for the detection of N-chloropiperidine at concentrations in aqueous solution of 10-7 M. The technique gives a quantity of derivative which is proportional to the concentration of chloramine present over the range examined (10-7 M to 10-4 M). High pressure liquid chromatographic separation of dansyl derivatives of amines and amino acids has been optimized using a fluorescence detector. This technique has been applied to the analysis of tap water. Liquid chromatograms of derivatized tap water reveal the presence of many organic N-chloramines.

description: Microbial life inhabiting subseafloor sediments plays an important role in Earth’s carbon cycle. However, the impact of geodynamic processes on the distributions and carbon-cycling activities of subseafloor life remains poorly constrained. We explore a submarine mud volcano of the Nankai accretionary complex by drilling down to 200 m below the summit. Stable isotopic compositions of water and carbon compounds, including clumped methane isotopologues, suggest that ~90% of methane is microbially produced at 16° to 30°C and 300 to 900 m below seafloor, corresponding to the basin bottom, where fluids in the accretionary prism are supplied via megasplay faults. Radiotracer experiments showed that relatively small microbial populations in deep mud volcano sediments (10 2 to 10 3 cells cm −3 ) include highly active hydrogenotrophic methanogens and acetogens. Our findings indicate that subduction-associated fluid migration has stimulated microbial activity in the mud reservoir and that mud volcanoes may contribute more substantially to the methane budget than previously estimated.

description: En 1974, después de casi un siglo de anonimato, el libro Recuerdos de la campaña de La Breña sale a la luz pública.1 La obra se cimenta en las memorias de doña Antonia Moreno de Cáceres. Esta señora revive escenas y episodios de su experiencia durante la Guerra del Pacífico (1879-1883), también conocida como la Guerra del guano, un conflicto territorial entre Perú, Bolivia y Chile. Doña Antonia vive la conflagración al lado de su esposo, el General Andrés Avelino Cáceres, líder militar de la campaña de La Breña. Las memorias de Moreno de Cáceres fueron trascritas por su hija Hortensia Cáceres de Porras, y más tarde editadas por Jossie Sison Porras de la Guerra, nieta de doña Antonia. La editora dice que estos manuscritos registran “otra campaña de conspiraciones en Lima,” de la cual se ocupó su abuela (8). En verdad, el relato de esta heroína peruana revela su patriotismo y resistencia contra los invasores chilenos. Doña Antonia explica que las hostilidades bélicas en Lima la obligaron a dejar la ciudad y a seguir la tropa liderada por su esposo. En ese sentido, el relato de Moreno de Cáceres revela que la guerra se convierte en un elemento circunstancial de resistencia y de viaje femenino. Las memorias de la heroína constituyen en sí un texto de corte feminista. La obra presenta, además un sesgo indigenista, debido a las referencias que la narradora hace sobre la agencia de las indígenas que operaron en la guerra. A partir de estos rasgos particulares de la obra, el presente ensayo estudiará las relaciones entre guerra y viaje. Propongo aquí que Recuerdos de la campaña de La Breña constituye un relato bélico y de viaje femenino, a través del cual doña Antonia reivindica su participación y la de las indígenas en la Guerra del Pacífico.

description: In the paper the covariant kernel of the nucleon-nucleon interaction of particles with scalar propagators is analyzed. The Bethe-Salpeter equation for the T matrix is considered in the rank- one separable kernel. The parameters of the kernel for the specific partial-wave channels explicitly connect with the observables { low energy scattering parameters and phase shifts, deuteron binding energy. Covariant separable kernels forthe partial-wave channels with total angular momentum J = 0 (1S0, 3P0) and J = 1 (3S1 -3D1, 1P1, 3P1) are constructed.

description: Magnetic and electronic properties of the recently-discovered material Sr8CaRe3Cu4O24 were investigated by means of a quantum Monte Carlo simulation, the Green function method and the LSDA+U (local spin-density approximation plus the Hubbard-U term) method. The LSDA+U calculation shows that the ground state is an insulator with magnetic moment M=1.01\muB/f.u., which is consistent with experimental results. The magnetic sites were specified and an effective model for the magnetic properties of this compound derived. The resultant effective model is a three-dimensional Heisenberg model with spin-alternation. Finite-temperature properties of this effective model are investigated by the quantum Monte Carlo method (continuous-time loop algorithm) and the Green function method. The numerical results are consistent with experimental results, indicating that the model is suitable for this material. Using the analysis of the effective model, some predictions for the material are made.

description: Conformal gravity has been proposed as an alternative theory of gravity which can account for flat galactic rotation curves without recourse to copious quantities of dark matter. However it was shown that for the usual choice of the metric, the result is catastrophic for null or highly relativistic geodesics, the effect is exactly the opposite yielding an effective repulsion and less deflection in this case. It is the point of this paper, that any result for massive geodesics depends on the choice of conformal gauge, in contradistinction to the case of null geodesics. We show how it is possible to choose the gauge so that the theory is attractive for all geodesics.

description: En la poesía de Carolina Coronado (1820-1911) encontramos un gran número de reflexiones sobre sus propios versos y en general sobre el papel de la poesía escrita por la mujer. De esta manera, el elemento metapoético adquiere una relevancia decisiva para comprender mejor la producción de la autora extremeña y por extensión la de las mujeres poetas que decidieron sacar a la luz sus escritos en el siglo XIX. Sara Pujol Russell señala que de los 577 poemas de Coronado, 107 desarrollan de una forma u otra el aspecto metaliterario (par. 1). La explicación a este fenómeno radica en las limitaciones que encontraba la mujer para expresar públicamente sus opiniones sobre su labor como poeta, lo que hizo que desarrollara sus ideas al respecto en sus poemas, ya que sus lectores simpatizarían con ella y la entenderían mejor que el resto de la sociedad.1

description: Recently, there has been considerable interest in the promise of new computing paradigms (CP) like the diskless computing paradigm, running applications off a network. The discussion on these CPs has focused mainly on the costs of ownership of the CPs. In this work, we adopt a grounded theory approach to identify and operationalize factors that are important in the decision space of senior IS managers, when deciding to adopt a CP for their organization. Using conjoint analysis, we measure the relative importance of these factors in their minds, and also whether the effect of these factors is linear or not. Our findings show that the software quality associated with a CP is the primary factor considered by IS managers. The effect of the cost factor is less important, non linear and in many cases unexpected.

description: Project managers face a challenge in aligning project requirements with project team members’ due to the fast-paced, competitive world in which information and communication technology (ICT) projects are run, as well as ICT professionals' constant evolving requirements. A project client measures a project success by how well has a project manager been able to meet project goals, while on the other hand software project teams (SPTs) measure project success by a manager’s ability to satisfy their project associated needs. This chapter purports that if projects’ requirements are properly aligned with team members’ requirements, then this will result in a balanced decision approach. Moreover, such an alignment will result in the realization of SPTs’ needs as well as meeting project’s needs. The chapter presents a Software Project’s needs and Software Project Team’s needs (SPnSPTn) alignment model and argues that a balanced decision, which meets both software project’s requirements and team members’ requirements can be achieved through the application of the SPnSPTn alignment model.

description: The excess of low invariant mass dilepton yield in heavy ion collisions arising from reduction in the rho meson mass at finite temperatures is partially suppressed because of the effect on the width of the rho meson induced by Bose enhancement, essentially due to emission of pions in a medium of the pion gas in the central rapidity region. The sensitivity of the effect on the initial temperature of the hadronic phase is also examined.

description: Sphingolipids are a class of lipids that share a sphingoid base backbone. They exert various effects in eukaryotes, ranging from structural roles in plasma membranes to cellular signaling. De novo sphingolipid synthesis takes place in the endoplasmic reticulum (ER), where the condensation of the activated C₁₆ fatty acid palmitoyl-CoA and the amino acid L-serine is catalyzed by serine palmitoyltransferase (SPT). The product, 3-ketosphinganine, is then converted into more complex sphingolipids by additional ER-bound enzymes, resulting in the formation of ceramides. Since sphingolipid homeostasis is crucial to numerous cellular functions, improved assessment of sphingolipid metabolism will be key to better understanding several human diseases. To date, no assay exists capable of monitoring de novo synthesis sphingolipid in its entirety. Here, we have established a cell-free assay utilizing rat liver microsomes containing all the enzymes necessary for bottom-up synthesis of ceramides. Following lipid extraction, we were able to track the different intermediates of the sphingolipid metabolism pathway, namely 3-ketosphinganine, sphinganine, dihydroceramide, and ceramide. This was achieved by chromatographic separation of sphingolipid metabolites followed by detection of their accurate mass and characteristic fragmentations through high-resolution mass spectrometry and tandem-mass spectrometry. We were able to distinguish, unequivocally, between de novo synthesized sphingolipids and intrinsic species, inevitably present in the microsome preparations, through the addition of stable isotope-labeled palmitate-d₃ and L-serine-d₃. To the best of our knowledge, this is the first demonstration of a method monitoring the entirety of ER-associated sphingolipid biosynthesis. Proof-of-concept data was provided by modulating the levels of supplied cofactors (e.g., NADPH) or the addition of specific enzyme inhibitors (e.g., fumonisin B₁). The presented microsomal assay may serve as a useful tool for monitoring alterations in sphingolipid de novo synthesis in cells or tissues. Additionally, our methodology may be used for metabolism studies of atypical substrates – naturally occurring or chemically tailored – as well as novel inhibitors of enzymes involved in sphingolipid de novo synthesis.

description: In nature as well as in the context of infection and medical applications, bacteria often have to move in highly complex environments such as soil or tissues. Previous studies have shown that bacteria strongly interact with their surroundings and are often guided by confinements. Here, we investigate theoretically how the dispersal of swimming bacteria can be augmented by microfluidic environments and validate our theoretical predictions experimentally. We consider a system of bacteria performing the prototypical run-and-tumble motion inside a labyrinth with square lattice geometry. Narrow channels between the square obstacles limit the possibility of bacteria to reorient during tumbling events to an area where channels cross. Thus, by varying the geometry of the lattice it might be possible to control the dispersal of cells. We present a theoretical model quantifying diffusive spreading of a run-and-tumble random walker in a square lattice. Numerical simulations validate our theoretical predictions for the dependence of the diffusion coefficient on the lattice geometry. We show that bacteria moving in square labyrinths exhibit enhanced dispersal as compared to unconfined cells. Importantly, confinement significantly extends the duration of the phase with strongly non-Gaussian diffusion, when the geometry of channels is imprinted in the density profiles of spreading cells. Finally, in good agreement with our theoretical findings, we observe the predicted behaviors in experiments with E. coli bacteria swimming in a square lattice labyrinth created in amicrofluidic device. Altogether, our comprehensive understanding of bacterial dispersal in a simple two-dimensional labyrinth makes the first step toward the analysis of more complex geometries relevant for real world applications.

description: How can we find patterns and anomalies in a tensor, or multi-dimensional array, in an efficient and directly interpretable way? How can we do this in an online environment, where a new tensor arrives each time step? Finding patterns and anomalies in a tensor is a crucial problem with many applications, including building safety monitoring, patient health monitoring, cyber security, terrorist detection, and fake user detection in social networks. Standard PARAFAC and Tucker decomposition results are not directly interpretable. Although a few sampling-based methods have previously been proposed towards better interpretability, they need to be made faster, more memory efficient, and more accurate. In this paper, we propose CTD, a fast, accurate, and directly interpretable tensor decomposition method based on sampling. CTD-S, the static version of CTD, provably guarantees a high accuracy that is 17 ~ 83x more accurate than that of the state-of-the-art method. Also, CTD-S is made 5 ~ 86x faster, and 7 ~ 12x more memory-efficient than the state-of-the-art method by removing redundancy. CTD-D, the dynamic version of CTD, is the first interpretable dynamic tensor decomposition method ever proposed. Also, it is made 2 ~ 3x faster than already fast CTD-S by exploiting factors at previous time step and by reordering operations. With CTD, we demonstrate how the results can be effectively interpreted in the online distributed denial of service (DDoS) attack detection.

description: Bertea subaptera Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 190.
 TYPE LOCALITY: Rondani gave no type locality in his original description but later (1860a: 57) added “ in Apennino parmensi ” [Parmese Apennines (Italy)].
 TYPE MATERIAL: 1 specimen, holotype (sex not determinable, missing all but part of the thorax, which is completely covered with mold) (MZUF: Box 62): Bertea Rnd. / subaptera Berté, Apenn. [= Apennines] / 3194.
 CURRENT STATUS: Menzel & Mohrig (2000: 601) placed it in Hymenoptera; we return it to Diptera, but treat it as incertae sedis. See Remarks.
 REMARKS: Rondani’s (1856: 190) key for the genus Bertea Rondani, 1856 lists Bertea subaptera as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. In his redescription, Rondani (1860a: 57) specified having just the male sex: “ semel marem [the male once]” collected by Dr. Bertè. Bezzi (1900b: 517) reported the MZUF holotype as being damaged and unrecognizable, but definitely a dipteran belonging to the family “ Mycetophilidae (Subfam. Sciarinae)”, currently the family Sciaridae. Menzel & Mohrig (2000: 601) claimed that it is a Hymenoptera, and O’Hara et al. (2011: 192) followed in treating the genus Bertea in Diptera. The MZUF holotype is indeed very damaged and, except for part of the thorax and one leg, covered with mold, but it is nonetheless clearly a dipteran. Rondani (1860a: 57) specified that the forewings are reduced and only slightly longer than the halteres (Fig. 30).

description: We obtain the quasinormal modes for tensor perturbations of Gauss-Bonnet (GB) black holes in $d=5, 7, 8$ dimensions and vector perturbations in $d = 5, 6, 7$ and 8 dimensions using third order WKB formalism. The tensor perturbation for black holes in $d=6$ is not considered because of the fact that it is unstable to tensor mode perturbations. In the case of uncharged GB black hole, for both tensor and vector perturbations, the real part of the QN frequency increases as the Gauss-Bonnet coupling ($α'$) increases. The imaginary part first decreases upto a certain value of $α'$ and then increases with $α'$ for both tensor and vector perturbations. For larger values of $α'$, the QN frequencies for vector perturbation differs slightly from the QN frequencies for tensorial one. It has also been shown that as $α' \to 0$, the quasinormal mode frequency for tensor and vector perturbation of the Schwarzschild black hole can be obtained. We have also calculated the quasinormal spectrum of the charged GB black hole for tensor perturbations. Here we have found that the real oscillation frequency increases, while the imaginary part of the frequency falls with the increase of the charge. We also show that the quasinormal frequencies for scalar field perturbations and the tensor gravitational perturbations do not match as was claimed in the literature. The difference in the result increases if we increase the GB coupling.

description: We calculate the total cross sections and probabilities of electromagnetic productions of electron, muon and tauon pair productions simultaneously. At the Large Hadron Collider (LHC), the available electromagnetic energy is sufficient to produce all kind of leptons coherently. The masses of muon and tauon are large, so their Compton wavelengths are small enough to interact with the colliding nuclei. Therefore, the realistic nuclear form factors are included in the calculations of electromagnetic pair productions. The cross section calculations show that, at the LHC energies, the probabilities of simultaneous productions of all kind of leptons are increased significantly compare to the RHIC energies. Experimentally, observing this simultaneous production can give us important informations about the strong QED.

description: We report the discovery of a new double-mode RR Lyrae variable (RRd) in the field of our Galaxy: CU Comae. CU Comae is the sixth such RRd identified to date and is the most metal-poor RRd ever detected. Based on BVI CCD photometry spanning eleven years of observations, we find that CU Comae has periods P0=0.5441641 +/-0.0000049d and P1=0.4057605 +/-0.0000018d. The amplitude of the primary (first-overtone) period of CU Comae is about twice the amplitude of the secondary (fundamental) period. The combination of the fundamental period of pulsation P0 and the period ratio of P1/P0=0.7457 places the variable on the metal-poor side of the Petersen diagram, in the region occupied by M68 and M15 RRd's. A mass of 0.83 solar masses is estimated for CU Comae using an updated theoretical calibration of the Petersen diagram. High resolution spectroscopy (R=30,000) covering the full pulsation cycle of CU Comae was obtained with the 2.7 m telescope of the Mc Donald Observatory, and has been used to build up the radial velocity curve of the variable. Abundance analysis done on the four spectra taken near minimum light (phase: 0.54 -- 0.71) confirms the metal poor nature of CU Comae, for which we derive [Fe/H]=-2.38 +/-0.20. This value places this new RRd at the extreme metal-poor edge of the metallicity distribution of the RR Lyrae variables in our Galaxy.

description: We study the stability of fixed points in the two-loop renormalization group for the random field O($N$) spin model in $4+ε$ dimensions. We solve the fixed-point equation in the 1/N expansion and $ε$ expansion. In the large-N limit, we study the stability of all fixed points. We solve the eigenvalue equation for the infinitesimal deviation from the fixed points under physical conditions on the random anisotropy function. We find that the fixed point corresponding to dimensional reduction is singly unstable and others are unstable or unphysical. Therefore, one has no choice other than dimensional reduction in the large-N limit. The two-loop $β$ function enables us to find a compact area in the $(d, N)$ plane where the dimensional reduction breaks down. We calculate higher-order corrections in the 1/N and $ε$ expansions to the fixed point. Solving the corrected eigenvalue equation nonperturbatively, we find that this fixed point is singly unstable also for sufficiently large $N$ and the critical exponents show a dimensional reduction.

description: How electrons get accelerated to relativistic energies in a high-Mach-number quasi-perpendicular shock is presented by means of ab initio particle-in-cell simulations in three dimensions. We found that coherent electrostatic Buneman waves and ion-Weibel magnetic turbulence coexist in a strong-shock structure whereby particles gain energy during shock-surfing and subsequent stochastic drift accelerations. Energetic electrons that initially experienced the surfing acceleration undergo pitch-angle diffusion by interacting with magnetic turbulence and continuous acceleration during confinement in the shock transition region. The ion-Weibel turbulence is the key to the efficient nonthermal electron acceleration.

description: Due to the internal structure of the nucleon, we should expect, in general, that the effective meson nucleon parameters may change in nuclear medium. We study such changes by using a chiral confining model of the nucleon. We use density-dependent masses for all mesons except the pion. Within a Dirac-Brueckner analysis, based on the relativistic covariant structure of the NN amplitude, we show that the effect of such a density dependence in the NN interaction on the saturation properties of nuclear matter, while not large, is quite significant. Due to the density dependence of the $g_{σNN}$, as predicted by the chiral confining model, we find, in particular, a looping behavior of the binding energy at saturation as a function of the saturation density. A simple model is described, which exhibits looping and which is shown to be mainly caused by the presence of a peak in the density dependence of the medium modified $σN$ coupling constant at low density. The effect of density dependence of the coupling constants and the meson masses tends to improve the results for $E/A$ and density of nuclear matter at saturation. From the present study we see that the relationship between binding energy and saturation density may not be as universal as found in nonrelativistic studies and that more model dependence is exhibited once medium modifications of the basic nuclear interactions are considered.

description: Additional file 2: Figure S1. a–c The role of Skp2 expression in the OS of patients with IDH1wt GBM, IDHwt LGG and even IDHmut LGG was analyzed. d, e The role of Skp2 expression in the OS of IDHmut LGG patients with or without 1p19q co-deletion was analyzed. Figure S2. Cell cycle cascade rate were detected in three cell lines, U87, U138 and LNZ308, upon LV, TMZ or combined treatments. With regard to the strong effect of TMZ in glioma cells, we chose 10 nM as the combination concentration of lovastatin in our study. Lovastatin caused a little bit of G2/M arrest in U87 and LNZ308, but not in U138 cell. The G1 phase cell numbers were enhanced in U138 and LNZ308 cells upon lovastatin treatment. Lovastatin did not further induce G2/M arrest when combined with TMZ in U87 and U138. However, in LNZ308 cells, lovastatin promoted G2/M arrest upon TMZ treatments dramatically. (*p < 0.05, **p < 0.01, ***p < 0.001). Figure S3. Lovastatin barely induced cell apoptosis in U87 and U138 cells but promoted cell apoptosis in LNZ308 cells markedly at 10 nM. When combined with TMZ, lovastatin did not promote the apoptotic cell rates in U87, and even antagonized the apoptosis induction effect in U138 and LNZ308 cells. (*p < 0.05, ***p < 0.001).
