description: Topological crystalline superconductors are known to have possible higher-order topology, which results in Majorana modes on $d-2$ or lower-dimensional boundaries. Given the rich possibilities of boundary signatures, it is desirable to have topological invariants that can predict the type of Majorana modes from band structures. Although symmetry indicators, a type of invariant that depends only on the band data at high-symmetry points, have been proposed for certain crystalline superconductors, there exist symmetry classes in which symmetry indicators fail to distinguish superconductors with different Majorana boundaries. Here, we systematically obtain topological invariants for an example of this kind, two-dimensional time-reversal symmetric superconductors with twofold rotational symmetry $C_2$. First, we show that the nontrivial topology is independent of band data on the high-symmetry points by conducting a momentum-space classification study. Then, from the resulting K groups, we derive calculable expressions for four $\mathbb{Z}_2$ invariants defined on high-symmetry lines or general points in the Brillouin zone. Finally, together with a real-space classification study, we establish the bulk-boundary correspondence and show that the four $\mathbb{Z}_2$ invariants can predict Majorana boundary types from band structures. Our proposed invariants can fuel practical material searches for $C_2$-symmetric topological superconductors featuring Majorana edge and corner modes.

description: Background. Recent data have suggested that regular aspirin use improves overall and cancer-specific survival in the subset of colorectal cancer (CRC) patients harboring PIK3CA mutations. However, the number of PIK3CA-mutated CRC patients examined in these studies was modest. Our collaborative study aims to validate the association between regular aspirin use and survival in patients with PIK3CA-mutated CRC.Patients and methods. Patients with PIK3CA-mutated CRC were identified at Moffitt Cancer Center (MCC) in the United States and Royal Melbourne Hospital (RMH) in Australia. Prospective clinicopathological data and survival data were available. At MCC, PIK3CA mutations were identified by targeted exome sequencing using the Illumina GAIIx Next Generation Sequencing platform. At RMH, Sanger sequencing was utilized. Multivariate survival analyses were conducted using Cox logistic regression.Results. From a cohort of 1487 CRC patients, 185 patients harbored a PIK3CA mutation. Median age of patients with PIK3CA-mutated tumors was 72 years (range: 34–92) and median follow up was 54 months. Forty-nine (26%) patients used aspirin regularly. Regular aspirin use was not associated with improved overall survival (multivariate HR 0.96, p = 0.86). There was a trend towards improved cancer-specific survival (multivariate HR 0.60, p = 0.14), but this was not significant.Conclusions. Despite examining a large number of patients, we did not confirm that regular aspirin use was associated with statistically significant improvements in survival in PIK3CA-mutated CRC patients. Prospective evaluation of this relationship is warranted.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Предметом исследования являются дисфункции институтов, возникающие при управлении и при осуществлении институциональных коррекций. Под дисфункцией мы понимаем расстройство функций института или системы, возникающее в силу различных причин, причем не только при трансплантации институтов из внешней в данную социально-экономическую среду, но и при функционировании существующих институтов и вновь вводимых проектируемых институтов. Рассматриваются лишь формальные институты. В качестве методологии исследования применяется морфологический и структурно-функциональный анализ, метод таксономии. Это позволило не только выделить вклад российской экономической школы в развитие теории дисфункций, типизировать дисфункции, но и раскрыть характер связи дисфункции и институциональной эффективности. Показано, что институциональные коррекции сами по себе могут оказаться подвержены дисфункциям, как по причине того, что объект управления характеризуется определенной величиной дисфункции, так и само государственное управление, в части своих базовых функций, также подвержено дисфункции. Эти два вида дисфункций могут усиливать друг друга. Такая реакция может возникать при вводе новых институтов внутри страны, что способно увеличивать трансакционные издержки, снижать адаптацию агентов, тормозить экономический рост и инновационное развитие. Поэтому организация государственного управления требует особого подхода, учитывающего каналы усиления дисфункции по объектам управления и по системе государственного управления. Результатом исследования выступают рекомендации, касающиеся преодоления дисфункции планирования, как одной из важнейших функций государственного управления. Также осуществлено уточнение постановки целей макроэкономического развития России, с акцентом на возможность организации новой модели ее экономического роста.

description: The study examines the impact of farmers’ perceptions and interpretations of climate-induced risks for agriculture in the catchment area of River Chambal in Madhya Pradesh, India. The research shows that farmers who perceived an increase in temperature are educated to more than the 8th grade, and that those who are aware of the decrease in the average precipitation over the years belong to the joint family type. A higher level of income and more farming experience significantly affect perceptions of the need for an increase in irrigation frequency. These results indicate the importance of investing in farmers’ education, encouraging joint family-based living, making sustained efforts to increase farmers’ income and making use of the experience of elder farmers.

description: The divalent metal transporter (DMT1) is well known for its roles in duodenal iron absorption across the apical enterocyte membrane, in iron efflux from the endosome during transferrin-dependent cellular iron acquisition, as well as in uptake of non-transferrin bound iron in many cells. Recently, using multiple approaches, we have obtained evidence that the mitochondrial outer membrane is another subcellular locale of DMT1 expression. While iron is of vital importance for mitochondrial energy metabolism, its delivery is likely to be tightly controlled due to iron's damaging redox properties. Here we provide additional support for a role of DMT1 in mitochondrial iron acquisition by immunofluorescence colocalization with mitochondrial markers in cells and isolated mitochondria, as well as flow cytometric quantification of DMT1-positive mitochondria from an inducible expression system. Physiological consequences of mitochondrial DMT1 expression are discussed also in consideration of other DMT1 substrates, such as manganese, relevant to mitochondrial antioxidant defense.

description: Gammachirp filterbank has been used to approximate the cochlea in sparse coding algorithms. An oriented grid search optimization was applied to adapt the gammachirp's parameters and improve the Matching Pursuit (MP) algorithm's sparsity along with the reconstruction quality. However, this combination of a greedy algorithm with a grid search at each iteration is computationally demanding and not suitable for real-time applications. This paper presents an adaptive approach to optimize the gammachirp's parameters but in the context of the Locally Competitive Algorithm (LCA) that requires much fewer computations than MP. The proposed method consists of taking advantage of the LCA's neural architecture to automatically adapt the gammachirp's filterbank using the backpropagation algorithm. Results demonstrate an improvement in the LCA's performance with our approach in terms of sparsity, reconstruction quality, and convergence time. This approach can yield a significant advantage over existing approaches for real-time applications.

description: Against the backdrop that most political economies across the globe need to promote transitions towards more environmentally sustainable public policies and economic practices, we ask what factors explain public support for and opposition to such trajectories among people living in different institutional and socio-economic contexts.To study this, we used survey data on individual attitudes from the International Social Survey Programme (ISSP) 2020 module on the environment. The dataset included a random sample of adult population in 28 countries. The analysis was organised in two steps. First, we examined whether improvement in living standards for people should now be prioritised over the preservation of nature for future generations, commonly referred to as the trade-off between economic growth and the environment. Next, we studied public support for and opposition to three specific environmental policy instruments: higher prices, higher taxes and decreased standard of living across numerous countries in the Global South and Global North. The countries differ greatly both in terms of human development, welfare systems and vulnerability to climate change. The motivation is to examine how these variations influence individual priorities in transition processes.The analysis results showed that the correlation between individual-level variables and pro-environmental attitudes varies across countries, and the results from the regression models were only partially in line with previous literature in this field. Importantly, typical explanatory factors identified in previous studies using data from Europe and North America explain, only to some degree, the variation in attitudes in other parts of the world. The explanatory power of our models is particularly weak in the case of acceptance of environmental policy instruments that facilitate the transition to more sustainable societies in countries with low rankings on the Human Development Index.

description: Objective: This meta-analysis systematically assessed the efficacy and safety of different doses of brivaracetam (BRV) compared with placebo as adjunctive therapy for adults with partial-onset epilepsy. Methods: Electronic and clinical trials databases were searched for randomized controlled trials of BRV published up to May 2015. We assessed the risk of bias of the included studies using the Cochrane Risk of Bias tool. The outcomes of interest included 50% responder rates, seizure freedom, the incidence of withdrawal and treatment-emergent adverse events (TEAEs). Results: Five trials met the inclusion criteria. Compared with placebo, 20, 50, 100 and 150 mg/day BRV was associated with significantly higher 50% responder rates. In addition, the effect of 50 mg BRV on seizure freedom was significantly different than that of placebo. Both fatigue and nasopharyngitis were significantly associated with 20 mg BRV, whereas fatigue and irritability were associated with 50 mg BRV. Somnolence was associated with 150 mg BRV. No significant differences were observed for the other common TEAEs. Conclusion: The use of BRV at doses > 5 mg/day resulted in statistically significant reduction in seizure frequency in respect to the 50% responder rate. BRV was reasonably tolerated by patients. These findings warrant confirmation in future studies.

description: In this letter, we propose a new proof-of-concept of optical nano-tweezer on the basis of a pair of dielectric rectangular rods capable of generating a novel class of controlled finite-volume near field light capsules. The finite-difference time-domain simulations of light spatial structure and optical trapping forces of the gold nanoparticle immersed in water demonstrate the physical concept of an in-plane subwavelength optical capsule, integrated with the microfluidic mesoscale device. It is shown that refractive index and distance between dielectric rectangular rods can control the shape and axial position of the optical capsule. Such an in-plane wavelength-scaled structure provides a new path for manipulating absorbing nano-particles including bio-particles in a compact planar architecture and should thus open promising perspectives in lab-on-a-chip domains.

description: To investigate the mechanisms of maternal–fetal interactions in the setting of gestational diabetes mellitus. We investigated the long-term effects of intrauterine mild hyperglycemia and a postnatal high-fat diet on the glucose metabolism of adult offspring, and explored the role of adiponectin on hepatic gluconeogenesis. Twenty-one pregnant Wistar rats were randomly divided into an intrauterine hyperglycemia group (group D, n = 14) and a control group (group C, n = 7). Offspring were divided into four groups according to intrauterine blood glucose level and post-weaning dietary patterns (high-fat diet groups: DF and CF or normal diet groups: DN and CN, n = 8 per group). The average birth weights of group D offspring were higher than for group C. In the DF rats, low adiponectin mRNA expression in perirenal and epididymal fat was significantly positively correlated with low hepatic AdipoR1 mRNA expression and significantly correlated with high hepatic PEPCK, G-6-Pase, and PGC-1α mRNA levels. In DF rats, hepatic P-AMPK was cytoplasmically located and its level was decreased; in these rats, hepatic CRTC2 was expressed in the nucleus and its level was significantly increased. Our study shows that the dietary structure of offspring has a large influence on the incidence of abnormal glucose tolerance.

description: The current response to an electromagnetic field in a Weyl or Dirac semimetal becomes nonlocal due to the chiral anomaly activated by an applied static magnetic field. The nonlocality develops under the conditions of the normal skin effect and is related to the valley charge imbalance generated by the joint effect of the electric field of the impinging wave and the static magnetic field. We elucidate the signatures of this nonlocality in the transmission of electromagnetic waves. The signatures include enhancement of the transmission amplitude and its specific dependence on the wave's frequency and the static magnetic field strength.

description: The recently reported \textit{A}V$_3$Sb$_5$ (\textit{A} = K, Rb, Cs) family of kagome metals are candidates for unconventional superconductivity and chiral charge density wave (CDW) order; both potentially arise from nested saddle points in their band structures close to the Fermi energy. Here we use chemical substitution to introduce holes into CsV$_3$Sb$_{5}$ and unveil an unconventionalcoupling of the CDW and superconducting states. Specifically, we generate a phase diagram for CsV$_3$Sb$_{5-x}$Sn$_{x}$ that illustrates the impact of hole-doping the system and lifting the nearest vHs toward and above $E_F$. Superconductivity exhibits a non-monotonic evolution with the introduction of holes, resulting in two "domes" peaked at 3.6\,K and 4.1\,K and the rapid suppression of three-dimensional CDW order. The evolution of CDW and superconducting order is compared with the evolution of the electronic band structure of CsV$_3$Sb$_{5-x}$Sn$_x$, where the complete suppression of superconductivity seemingly coincides with an electron-like band comprised of Sb $p_z$ orbitals pushed above E$_F$.

description: We develop a symmetry-based low-energy theory for monolayer $\mathrm{WTe}_2$ in its 1T$^{\prime}$ phase, which includes eight bands (four orbitals, two spins). This model reduces to the conventional four-band spin-degenerate Dirac model near the Dirac points of the material. We show that measurements of the spin susceptibility, and of the magnitude and time dependence of the anomalous Hall conductivity induced by injected or equilibrium spin polarization can be used to determine the magnitude and form of the spin-orbit coupling Hamiltonian, as well as the dimensionless tilt of the Dirac bands.

description: Pendant le projet national CEOS.fr, plusieurs expériences ont été conduites sur des structures massives en béton armé afin d’étudier la fissuration sous retrait gêné de ces structures. Trois poutres en forme de I ayant une section centrale de 0,8m par 0,5met dont le retrait était gêné ont été testées. Des exemples de l’évolution de la température, des déformations et des forces sont donnés. Une analyse du processus de fissuration a montré que les fissures apparaissent pour une contrainte plus faible que la résistance en traction. A partir des mesures de déformations, les forces et contraintes dans le béton et dans les armatures peuvent être déduites. Des modélisations permettent aussi d’avoir l’état de contraintes dans les sections au très jeune âge, avant la première fissuration. Une analyse des essais permet de proposer un scénario réaliste du comportement. Enfin, des recommandations quant à l’évolution des codes dans le cas des structures massives sont proposées concernant notamment l’effet d’échelle probabiliste, les pourcentages minimaux d’armatures et l’effet combiné de la fissuration au jeune âge et en service.

description: A small number of superconductors are believed to exhibit intrinsic spin triplet pairing, and they are often discussed in terms of a simple, $^3$He-like picture where ferromagnetic spin fluctuations provide the "glue". However, in some cases in which reliable inelastic neutron scattering measurements are available, spin excitations are found to be peaked at finite momentum $\bf q$ rather than ${\bf q}=0$. Here we investigate some simple models that exhibit triplet pairing arising from antiferromagnetic spin fluctuations. We show that a strong peak at larger ${\bf q}$ in the magnetic susceptibility can drive such states and can give rise to pairing states with nodes in the $k_z$ plane even in the presence of a pure 2D Fermi surface. In these situations, dominant pair scattering processes occur between Fermi surface segments with like signs of the superconducting order parameter, yet they are consistent with an overall odd parity state. We examine the applicability of these scenarios to putative triplet superconductors UTe$_2$ by calculations based on three dimensional Fermi surfaces.

description: The coannihilation mechanism is a well-motivated alternative to the simple thermal freeze-out mechanism, where the dark matter relic density can be obtained through the coannihilation with a partner particle of similar mass with dark matter. When the partner particle is neutral, the inelastic nature of dark matter can help it to escape the direct detection limits. In this work, we focus on the coannihilation scenario in which the annihilation cross section is dominated by the partner-partner pair annihilation. We pay special interest on the parameter space where the coannihilation partner is long-lived, which leads to displaced signatures at the collider. In such case, it opens the heavy mass parameter space for the coannihilation dark matter, comparing with those dominated by the partner-dark matter annihilation. Specifically, we propose an inelastic scalar dark matter model with a broken symmetry, which realizes the domination of partner-partner pair annihilation. Then, we study two different realizations of the coannihilation partner decay and the existing constraints from the relic abundance, direct and indirect dark matter detection and the collider searches. We focus on the channel that the long-lived coannihilation partner decays to dark matter plus leptons. The high-luminosity LHC can reach good sensitivities for such heavy dark matter and coannihilation partner around 100--700 GeV.

description: To investigate the mechanisms of maternal–fetal interactions in the setting of gestational diabetes mellitus. We investigated the long-term effects of intrauterine mild hyperglycemia and a postnatal high-fat diet on the glucose metabolism of adult offspring, and explored the role of adiponectin on hepatic gluconeogenesis. Twenty-one pregnant Wistar rats were randomly divided into an intrauterine hyperglycemia group (group D, n = 14) and a control group (group C, n = 7). Offspring were divided into four groups according to intrauterine blood glucose level and post-weaning dietary patterns (high-fat diet groups: DF and CF or normal diet groups: DN and CN, n = 8 per group). The average birth weights of group D offspring were higher than for group C. In the DF rats, low adiponectin mRNA expression in perirenal and epididymal fat was significantly positively correlated with low hepatic AdipoR1 mRNA expression and significantly correlated with high hepatic PEPCK, G-6-Pase, and PGC-1α mRNA levels. In DF rats, hepatic P-AMPK was cytoplasmically located and its level was decreased; in these rats, hepatic CRTC2 was expressed in the nucleus and its level was significantly increased. Our study shows that the dietary structure of offspring has a large influence on the incidence of abnormal glucose tolerance.

description: A search for low-mass dilepton resonances in Higgs boson decays is conducted in the four-lepton final state. The decay is assumed to proceed via a pair of beyond the standard model particles, or one such particle and a Z boson. The search uses proton-proton collision data collected with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 137 fb$^{-1}$, at a center-of-mass energy $\sqrt{s} =$ 13 TeV. No significant deviation from the standard model expectation is observed. Upper limits at 95% confidence level are set on model-independent Higgs boson decay branching fractions. Additionally, limits on dark photon and axion-like particle production, based on two specific models, are reported.

description: Benchmarking of robotic manipulations is one of the open issues in robotic research. An important factor that has enabled progress in this area in the last decade is the existence of common object sets that have been shared among different research groups. However, the existing object sets are very limited when it comes to cloth-like objects that have unique particularities and challenges. This paper is a first step towards the design of a cloth object set to be distributed among research groups from the robotics cloth manipulation community. We present a set of household cloth objects and related tasks that serve to expose the challenges related to gathering such an object set and propose a roadmap to the design of common benchmarks in cloth manipulation tasks, with the intention to set the grounds for a future debate in the community that will be necessary to foster benchmarking for the manipulation of cloth-like objects. Some RGB-D and object scans are also collected as examples for the objects in relevant configurations. More details about the cloth set are shared in http://www.iri.upc.edu/groups/perception/ClothObjectSet/HouseholdClothSet.html.

description: There is a certain violence to South African born poet John Mateer’s fourth collection of poems to be published in Australia: Loanwords. Or, to be more precise, there is the certainty of violence, a need to bear witness - poetically - to the vicinity of terror. The first poem of the collection is called “The Bombing.” The poet there writes, “We see the aftermath in a sports shoe store / on a TV high against the ceiling … The vicinity is inarticulate.” The poem is about the phenomenon of a terrorist bombing, but a contemporary reader would be forgiven for asking: which “inarticulate vicinity” does the poet here have in mind? The specificity of this question does not seem entirely misplaced. The poem could be post September 11, 2001. It is definitely pre Bali October 12, 2002. For the Australian reader, for whom terror has entered the vicinity, its effect now takes place in the nervous intercultural spacetime opened up by these two dates and by the phenomenon of global terror.

description: Open quantum systems interacting with an environment exhibit dynamics described by the combination of dissipation and coherent Hamiltonian evolution. Taken together, these effects are captured by a Liouvillian superoperator. The degeneracies of the (generically non-Hermitian) Liouvillian are exceptional points, which are associated with critical dynamics as the system approaches steady state. We use a superconducting transmon circuit coupled to an engineered environment to observe two different types of Liouvillian exceptional points that arise either from the interplay of energy loss and decoherence or purely due to decoherence. By dynamically tuning the Liouvillian superoperators in real time we observe a non-Hermiticity-induced chiral state transfer. Our study motivates a new look at open quantum system dynamics from the vantage of Liouvillian exceptional points, enabling applications of non-Hermitian dynamics in the understanding and control of open quantum systems.

description: We estimate the mass accretion rate (MAR) of the 346 clusters of galaxies in the HectoMAP Cluster Survey. The clusters span the redshift range $0.17-0.42$ and the $M_{200}$ mass range $\approx (0.5 - 3.5)\cdot 10^{14} M_\odot$. The MAR estimate is based on the caustic technique along with a spherical infall model. Our analysis extends the measurement of MARs for 129 clusters at $z<0.3$ from the Cluster Infall Regions in the Sloan Digital Sky Survey (CIRS) and the Hectospec Cluster Survey (HeCS) to redshift $z \sim 0.42$. Averaging over redshift, low-mass clusters with $M_{200}\sim 0.7\cdot 10^{14} M_\odot$ accrete $\sim 3\cdot 10^4 M_\odot$yr$^{-1}$; more massive clusters with $M_{200}\sim 2.8\cdot 10^{14} M_\odot$ accrete $\sim 1\cdot 10^5 M_\odot$yr$^{-1}$. Low- and high-mass clusters increase their MAR by $\sim 46\%$ and $\sim 84\%$, respectively, as the redshift increases from $z\sim 0.17-0.29$ to $z\sim 0.34-0.42$. The MARs at fixed redshift increase with mass and MARs at fixed mass increase with redshift in agreement with $Λ$CDM cosmological model for hierarchical structure formation. We consider the extension of MAR measurements to $z \sim 1$.

description: Objectives: This study aims to investigate whether variations in LIPC, CETP, ABCA1 and LPL, which are involved in high-density lipoprotein (HDL) metabolism, are associated with advanced age-related macular degeneration (AMD) in the Chinese population.Design and Methods: A total of 119 Chinese patients with advanced AMD and 99 control individuals were recruited. Genomic DNA was extracted from peripheral blood leukocytes. Genotypes of seven single nucleotide polymorphisms (SNPs) including rs1061170 and rs1410996 in CFH, rs10490924 in HTRA1, rs10468017 in LIPC, rs3764261 in CETP, rs1883025 in ABCA1 and rs12678919 near LPL were determined by polymerase chain reaction (PCR) followed by allele-specific restriction enzyme digestion or SNaPshot. Unconditional logistic regression analyses were performed to generate a risk predictive model.Results: We observed the frequency of allele A of rs3764261 in CETP to be significantly lower in advanced AMD after Bonferroni correction (15.5% in patients with AMD and 20.7% in controls; OR = 0.49, 95% CI: 0.29–0.85; p = 0.011). Furthermore, we found that it was also associated with reduced risk of both unilateral AMD (OR = 0.52, 95% CI: 0.28–0.98; p = 0.043) and bilateral AMD (OR = 0.45, 95% CI: 0.22–0.91; p = 0.026). Rs10468017 in LIPC, rs12678919 near LPL and rs1883025 in ABCA1 were not found to be associated with advanced AMD (all p > 0.05).Conclusion: Our data suggested that the allele A in rs3764261 in CETP gene may be associated with a decreased risk of advanced AMD in Chinese population.
Estimating QCD-factorization amplitudes through $SU(3)$ symmetry in $B\rightarrow P P$ decays

description: We estimate the potential size of the weak annihilation amplitudes in QCD factorization as allowed by experimental data. To achieve this goal, we establish a connection between the amplitudes in the QCD factorization and the so-called topological and $SU(3)$-invariant descriptions. Our approach is based purely on the analysis of the tensor structure of the decay amplitudes. By focusing on the processes $B\rightarrow P P$ and considering data from CP asymmetries and branching fractions, we perform a global fit to the $SU(3)$-irreducible quantities assuming minimal theoretical bias. Subsequently we translate the outcome to the QCD factorization decomposition, and find that the most constrained weak annihilation amplitudes are below $4\%$. However, in view of the large uncertainties in several of the experimental input parameters, values up to $30\%$ are allowed in certain cases.
