description: We show that the second accelerating expansion of the universe appears smoothly from the decelerating universe remarkably after the initial inflation in the two-dimensional soluble semi-classical dilaton gravity along with the modified Poisson brackets of noncommutativity between the relevant fields. However, the ordinary solution coming from the equations of motion following the conventional Poisson algebra describes permanent accelerating universe without any phase change. In this modified model, it turns out that the phase transition is related to the noncommutative Poisson algebra.

description: Using a first principles approach, we studied the hydrogen evolution reaction activity of newly synthesized biphenylene and B, N, P decorated biphenylene sheet. hydrogen evolution reaction activity of pristine biphenylene sheet is not encouraging, as it is similar to pristine graphene. The Gibbs free energy and overpotential of P(N) doped on biphenylene sheet are 0.022 (-0.092) eV and 22 (92) mV, respectively. The reported Gibbs free energy and overpotential of Pt are 0.9 eV and 90 mV. Hence doping of P(N) atom on top of biphenylene sheet improves hydrogen evolution reaction activity much better (near to) Pt metal. We analyzed the adsorption mechanism of dopants (B, N, P) and hydrogen with Bader charge analysis and density of states analysis. P and N-decoration on biphenylene sheet change its electronic structure so that one obtains improved hydrogen evolution reaction activity for P and N-doped biphenylene sheet. Furthermore, the stability of N, P decorated biphenylene at room temperature with ab initio molecular dynamics and formation energy near that of biphenylene indicate experimental feasibility. We have compared all our best hydrogen evolution reaction activity results in the reaction coordinate and volcano plots of pristine, B, N, and P-doped BPh sheets. They indicate that P-doped biphenylene is a metal-free, powerful catalyst for hydrogen evolution reaction activities.

description: We present a flexible discretization technique for computational models of thin tubular networks embedded in a bulk domain, for example a porous medium. These systems occur in the simulation of fluid flow in vascularized biological tissue, root water and nutrient uptake in soil, hydrological or petroleum wells in rock formations, or heat transport in micro-cooling devices. The key processes, such as heat and mass transfer, are usually dominated by the exchange between the network system and the embedding domain. By explicitly resolving the interface between these domains with the computational mesh, we can accurately describe these processes. The network is efficiently described by a network of line segments. Coupling terms are evaluated by projection of the interface variables. The new method is naturally applicable for nonlinear and time-dependent problems and can therefore be used as a reference method in the development of novel implicit interface 1D-3D methods and in the design of verification benchmarks for embedded tubular network methods. Implicit interface, not resolving the bulk-network interface explicitly have proven to be very efficient but have only been mathematically analyzed for linear elliptic problems so far. Using two application scenarios, fluid perfusion of vascularized tissue and root water uptake from soil, we investigate the effect of some common modeling assumptions of implicit interface methods numerically.

description: If inflation was preceded by a radiation era then at the time of inflation there will exist a decoupled thermal distribution of gravitons. Gravitational waves generated during inflation will be amplified by the process of stimulated emission into the existing thermal distribution of gravitons. Consequently the usual zero temperature scale invariant tensor spectrum is modified by a temperature dependent factor. This thermal correction factor amplify the $B$-mode polarization of the CMB by an order of magnitude at large angles, which may now be in the range of observability of WMAP.

The necessity of tRNA-Val-CAC-1-1 derived tRNA fragments (tRFs) in drosophila
Creators: name: Gattone, Nicholas
Publisher: name: No Publisher Supplied
Year: 2021

description: Small non-coding RNAs, such as micro-RNAs (miRNAs) or small interfering RNAs (siRNAs) are critical regulators of gene expression during tissue development. tRNA-derived fragments are a newly discovered class of small non-coding RNA that participate in different biological processes, some of which are attributed to post-transcriptional regulation similar to miRNAs. Using a computational pipeline designed to find tRF targets by mirroring a miRNA-like seed-based targeting mechanism, we identified that the tRNA-Val-CAC-1-1 contains a seed sequence that may target epidermal growth factor receptor (EGFR) inhibitor Sprouty. Using CRISPR/Cas9 genome engineering, this tRNA was deleted. The transgenic fly remained heterozygous, suggesting a necessary role for fly survival. The RNA-seq data from the heterozygous fly did demonstrate small transcriptional changes for target genes in both the ovary and embryo. In addition, a global change in the distribution of small RNAs was found, suggesting a possible stress reaction on the small RNA level from the targeted deletion. Further CRISPR experiments are underway to determine the reason for the unviability of the tRNA-Val-CAC-1-1 homozygous mutant.

description: Quantum matrix geometry is the underlying geometry of M(atrix) theory. Expanding upon the idea of level projection, we propose a quantum-oriented non-commutative scheme for generating the matrix geometry of the coset space $G/H$. We employ this novel scheme to unveil unexplored matrix geometries by utilizing gauged quantum mechanics on higher dimensional spheres. The resultant matrix geometries manifest as $\it{pure}$ quantum Nambu geometries: Their non-commutative structures elude capture through the conventional commutator formalism of Lie algebra, necessitating the introduction of the quantum Nambu algebra. This matrix geometry embodies a one-dimension-lower quantum internal geometry featuring nested fuzzy structures. While the continuum limit of this quantum geometry is represented by overlapping classical manifolds, their fuzzification cannot reproduce the original quantum geometry. We demonstrate how these quantum Nambu geometries give rise to novel solutions in Yang-Mills matrix models, exhibiting distinct physical properties from the known fuzzy sphere solutions.

Especially, five young star clusters are identified in the (J-H, H-K) two color diagram and the total extinction values toward these clusters are estimated to be A_V =2 - 6 from the comparison with the theoretical values given by the Leitherer et al. (1999)'s theoretical star cluster model.

3DHR-Co: A Collaborative Test-time Refinement Framework for In-the-Wild 3D Human-Body Reconstruction Task

description: The field of 3D human-body reconstruction (abbreviated as 3DHR) that utilizes parametric pose and shape representations has witnessed significant advancements in recent years. However, the application of 3DHR techniques to handle real-world, diverse scenes, known as in-the-wild data, still faces limitations. The primary challenge arises as curating accurate 3D human pose ground truth (GT) for in-the-wild scenes is still difficult to obtain due to various factors. Recent test-time refinement approaches on 3DHR leverage initial 2D off-the-shelf human keypoints information to support the lack of 3D supervision on in-the-wild data. However, we observed that additional 2D supervision alone could cause the overfitting issue on common 3DHR backbones, making the 3DHR test-time refinement task seem intractable. We answer this challenge by proposing a strategy that complements 3DHR test-time refinement work under a collaborative approach. Specifically, we initially apply a pre-adaptation approach that works by collaborating various 3DHR models in a single framework to directly improve their initial outputs. This approach is then further combined with the test-time adaptation work under specific settings that minimize the overfitting issue to further boost the 3DHR performance. The whole framework is termed as 3DHR-Co, and on the experiment sides, we showed that the proposed work can significantly enhance the scores of common classic 3DHR backbones up to -34 mm pose error suppression, putting them among the top list on the in-the-wild benchmark data. Such achievement shows that our approach helps unveil the true potential of the common classic 3DHR backbones. Based on these findings, we further investigate various settings on the proposed framework to better elaborate the capability of our collaborative approach in the 3DHR task.

description: We study the influence of the factor of electron-ion collisions on the solution of the Cauchy problem in the one-dimensional relativistic model of cold plasma and show that, depending on their intensity and initial data, two scenarios are possible: either the solution remains smooth and stabilizes to a stationary state, or during a finite time the oscillations blowup. In contrast to the nonrelativistic model, when exact conditions can be obtained separating the two behaviors, in a much more complicated relativistic situation, it turns out to be possible to analytically estimate from below the time during which the existence of a smooth solution and the guaranteed number of oscillations during this time. In addition, we show that in contrast to the relativistic case without taking into account collisions, when oscillations corresponding to arbitrarily small deviations from the zero equilibrium position blow up, the presence of electron collisions can suppress the blow-up of sufficiently small oscillations. Further, based on the analysis of characteristics, a numerical algorithm is constructed, the order of accuracy of which is determined only by the smoothness of the initial data. Numerical experiments are presented to illustrate the theoretical results. The initial conditions are chosen as reasonably as possible from the point of view of full-scale physical experiments.

description: Theoretical models of spiral arms suggest that the spiral arms provoke a vertical bulk motion in disc stars. By analysing the breathing motion, a coherent asymmetric vertical motion around the mid-plane of the Milky Way disc, with $\textit{Gaia}$ DR3, we found that a compressing breathing motion presents along the Local arm. On the other hand, with an $N$-body simulation of an isolated Milky Way-like disc galaxy, we found that the transient and dynamic spiral arms induce compressing breathing motions when the arms are in the growth phase, while the expanding breathing motion appears in the disruption phase. The observed clear alignment of the compressing breathing motion with the Local arm is similar to what is seen in the growth phase of the simulated spiral arms. Hence, we suggest that the Local arm's compressing breathing motion can be explained by the Local arm being in the growth phase of a transient and dynamic spiral arm. We also identified the tentative signatures of the expanding breathing motion associated with the Perseus arm and also the Outer arm coinciding with the compressing breathing motion. This may infer that the Perseus and Outer arms are in the disruption and growth phases, respectively.

Identification and analysis of the signalling networks that regulate Ciz1 levels in normal and cancer cell lines
Creators: name: Pauzaite, Tekle
Publisher: name: Lancaster University
Year: 2019

description: Ciz1 is a nuclear protein that associates with cyclin A – cyclin dependent kinase 2 (CDK2) and facilitates the initiation of DNA replication. Ciz1 overexpression has been linked to common cancer types, including breast, colon, prostate, lung, and liver cancers. This suggests that identification of mechanisms that regulate Ciz1 levels may represent potential drug targets in cancer. This work identifies that CDK2 and DDK activity are required to maintain Ciz1 levels. Chemical or genetic inhibition of CDK2 or DDK (Cdc7-Dbf4) activity in murine fibroblasts reduced Ciz1 levels. Further analysis demonstrated that CDK and DDK activity promotes Ciz1 accumulation in G1 phase by reducing ubiquitin proteasome system (UPS) mediated degradation. Furthermore, Ciz1 levels are actively controlled by the proteasome, as inhibition of protein translation rapidly reduced Ciz1 levels, and this is reversed by proteasomal inhibition. The data suggest a model where Ciz1 is regulated by opposing kinase and UPS activities, leading to Ciz1 accumulation in response to rising kinase activity in G1 phase, and its degradation later in the cell cycle. Significantly, human prostate adenocarcinoma (PC3) and oestrogen receptor positive breast cancer (MCF7) cell lines require Ciz1 for efficient proliferation. The data demonstrate that Ciz1 levels can be reduced with CDK2/ DDK inhibitors via proteasomally mediated degradation in human cancer cell lines similarly to normal fibroblasts. In PC3 and MCF7 cell lines, repurposing small molecule CDK2 inhibitors efficiently reduce Ciz1 levels, decrease E2F mediated transcription and proliferation. The targeted depletion of Ciz1 via CDK2/ DDK inhibition and UPS mediated degradation requires a functional E3 ligase to be effective. As a first step towards identifying the regulatory E3 ligase(s), a biochemical fractionation and mass spectrometry approach revealed three putative E3 ligases: UBR5, FBXO8 and UBE2O, which require further characterisation. Taken together, this work suggests that deregulation of CDK activity or inactivation of UPS signalling may promote Ciz1 overexpression in specific cancers. Importantly, Ciz1 is required for proliferation of some cancer cell lines, suggesting that approaches, which reduce Ciz1 levels may be of clinical benefit. Therefore, the identification of the regulatory mechanisms that control Ciz1 levels, represent potential targets in Ciz1 dependent cancers.

description: According to the $Λ$ cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected. The effects of interactions between dwarf galaxies on their evolution are not well understood. In this study, we aim to understand the effect of low-mass galaxy interactions on their star formation rate (SFR). We estimated the SFR of 22 interacting and 36 single gas-rich dwarf galaxies in the Lynx-Cancer void region using their far-ultraviolet (FUV) images from the GALEX mission. We find an enhancement in SFR by a factor of 3.4$\pm$1.2 for interacting systems compared to single dwarf galaxies in the stellar mass range of 10$^{7}$ - 10$^{8}$ M$\odot$. Our results indicate that dwarf - dwarf galaxy interactions can lead to an enhancement in their SFR. These observations are similar to the predictions based on the simulations of dwarf galaxies at lower redshifts. Future deeper and higher-spatial-resolution UV studies will help us to understand the effect of dwarf galaxy interactions on the spatial distribution of star forming clumps and to identify star formation in tidal tails.

description: Enacted to provide more competitive pricing of U.S. farm goods in foreign and domestic markets and to reduce surplus stocks of grain and dairy products, the Food Security Act of 1985 affects consumers in several ways. This report compares these effects with what might have happened if 1981 farm legislation had remained in effect. Consumers will he able to buy more food with their dollars under the 1985 legislation. The implicit tax burden associated with financing Federal farm programs is reduced for low- and moderate-income people, and shifted to persons in higher tax brackets. Eligibility requirements for food assistance programs are broadened and benefits are increased, enabling wider participation by the needy.

description: We consider the entanglement of closed bosonic strings intersecting the event horizon of a Rindler spacetime and, by using some simplified (rather semiclassical) arguments and some elements of the string field theory, we show the existence of a critical temperature beyond which closed strings \emph{cannot be in thermal equilibrium}. The order of magnitude of this critical value coincides with the Hagedorn temperature, which suggests an interpretation consistent with the fact of having a partition function which is bad defined for temperatures higher than it. Possible implications of the present approach on the microscopical structure of stretched horizons are also pointed out.

description: The widespread use of disposable facemasks during the COVID-19 pandemic has led to environmental widespread concern due to microplastic pollution. Biodegradable disposable facemasks are a first step to reducing the environmental impact of pandemics. In this paper we present high-performance facemask components based on novel poly(ester amide) (PEA) grades synthesized from bio-sourced materials and processed into non-woven facemask components. PEA based polymers present an excellent compromise between mechanical performance and biodegradability. Importantly, the properties of the PEA can easily be tuned by changing the ratio of the ester and amides, or variation of diol and diacid part. We synthesized seven polymers which we optimized for biodegradability and processability. Among them, two grades combined electrospinning process compatibility with full degradation within 35 days, using a normalized biodegradation test. The ultra-thin filters thus developed were evaluated for performance on a custom-made characterization bench. The filters achieved a microparticle capture efficiency and breathability comparable to commercial filters. Another PEA grade was optimized to reach optimal visco-thermal properties that made it compatible with solvent-free melt-spinning process as demonstrated with continuous fibres production. Overall, our environmentally friendly solution paves the way for the fabrication of high-performance fibres with excellent biodegradability for the next generation facemasks.

description: We explore the perspectives of studying vacuum birefringence at the Gamma Factory. To this end, we assess in detail the parameter regime which can be reliably analyzed resorting to the leading contribution to the Heisenberg-Euler effective Lagrangian. We explicitly show that -- contrarily to naive expectations -- this approach allows for the accurate theoretical study of quantum vacuum signatures up to fairly large photon energies. The big advantage of this parameter regime is the possibility of studying the phenomenon in experimentally realistic, manifestly inhomogeneous pump and probe field configurations. Thereafter, we focus on two specific scenarios giving rise to a vacuum birefringence effect for traversing gamma probe photons. In the first scenario the birefringence phenomenon is induced by a quasi-constant static magnetic field. In the second case it is driven by a counter-propagating high-intensity laser field.

description: Employing the time-dependent variational principle combined with the multiple Davydov $\mathrm{D}_2$ Ansatz, we investigate Landau-Zener (LZ) transitions in a qubit coupled to a photon mode with various initial photon states at zero temperature. Thanks to the multiple Davydov trial states, exact photonic dynamics taking place in the course of the LZ transition is also studied efficiently. With the qubit driven by a linear external field and the photon mode initialized with Schrödinger-cat states, asymptotic behavior of the transition probability beyond the rotating-wave approximation is uncovered for a variety of initial states. Using a sinusoidal external driving field, we also explore the photon-assisted dynamics of Landau-Zener-Stückelberg-Majorana interferometry. Transition pathways involving multiple energy levels are unveiled by analyzing the photon dynamics.

description: We carried out a sensitive survey of C$_2$ and C$_3$ using the EDIBLES data set. We also expanded our searches to C$_4$, C$_5$, and $^{13}$C$^{12}$C isotopologue in the most molecule-rich sightlines.
 We fit synthetic spectra generated following a physical excitation model to the C$_2$ (2-0) Phillips band to obtain the C$_2$ column density ($N$) as well as the kinetic temperature ($T_\textrm{kin}$) and number density ($n$) of the host cloud. The C$_3$ molecule was measured through its $\tilde{A} - \tilde{X}$ (000-000) electronic origin band system. We simulated the excitation of this band with a double-temperature Boltzmann distribution.
 We present the largest combined survey of C$_2$ and C$_3$ to date in which the individual transitions can be resolved. In total we detected C$_2$ in 51 velocity components along 40 sightlines, and C$_3$ in 31 velocity components along 27 sightlines. The two molecules are detected in the same velocity components. We find a very good correlation between $N$(C$_2$) and $N$(C$_3$) with Pearson $r = 0.93$ and an average $N$(C$_2$)/$N$(C$_3$) ratio of 15.5$\pm$1.4. A comparison with the behaviour of the C$_2$ DIBs shows that there are no clear differences among sightlines with and without detection of C$_2$ and C$_3$. This is in direct contrast to the better-studied non-C$_2$ DIBs who have reduced strengths in molecule-rich environments. We also identify for the first time the $Q$(2), $Q$(3), and $Q$(4) transitions of the $^{13}$C$^{12}$C (2-0) Phillips band in a stacked average spectrum, and estimate the isotopic ratio of carbon $^{12}$C/$^{13}$C as 79$\pm$8.

description: We derive the bulk viscous damping timescale of hybrid stars, neutron stars with quark matter core. The r-mode instability windows of the stars show that the theoretical results are consistent with the rapid rotation pulsar data, which may give an indication for the existence of quark matter in the interior of neutron stars. Hybrid stars instead of neutron or strange stars may lead to submillisecond pulsars.

The moduli space of hyper-K{ä}hler four-fold compactifications

Subjects: subject: High Energy Physics - Theory (hep-th)

description: I discuss some aspects of the moduli space of hyper-K{ä}hler four-fold compactifications of type II and ${\cal M}$- theories. The dimension of the moduli space of these theories is strictly bounded from above. As an example I study Hilb$^2(K3)$ and the generalized Kummer variety $K^2(T^4)$. In both cases RR-flux (or $G$-flux in ${\cal M}$-theory) must be turned on, and we show that they give rise to vacua with ${\cal N}=2$ or ${\cal N}=3$ supersymmetry upon turning on appropriate fluxes. An interesting subtlety involving the symmetric product limit $S^2(K3)$ is pointed out.

Quantum communication without alignment using multiple-qubit single-photon states

description: We propose a scheme for encoding logical qubits in a subspace protected against collective rotations around the propagation axis using the polarization and transverse spatial degrees of freedom of single photons. This encoding allows for quantum key distribution without the need of a shared reference frame. We present methods to generate entangled states of two logical qubits using present day down-conversion sources and linear optics, and show that the application of these entangled logical states to quantum information schemes allows for alignment-free tests of Bell's inequalities, quantum dense coding and quantum teleportation.

description: We analyze in detail the most singular behaviour of processes involving triple-collinear splittings with massive particles in the quasi-collinear limit, and present compact expressions for the splitting amplitudes and the corresponding splitting kernels at the squared-amplitude level. Our expressions fully agree with well-known triple-collinear splittings in the massless limit, which are used as a guide to achieve the final expressions. These results are important to quantify dominant mass effects in many observables, and constitute an essential ingredient of current high-precision computational frameworks for collider phenomenology.

Design of slow-light-enhanced bimodal interferometers using dimensionality reduction techniques

description: Interferometers usually require long paths for the ever-increasing requirements of high-performance operation, which hinders the miniaturization and integration of photonic circuits into very compact devices. Slow-light based interferometers provide interesting advantages in terms of both compactness and sensitivity, although their optimization is computationally costly and inefficient, due to the large number of parameters to be simultaneously designed. Here we propose the design of slowlight-enhanced bimodal interferometers by using principal component analysis to reduce the high-dimensional design space. A low-dimensional hyperplane containing all optimized designs is provided and investigated for changes in the silicon core and cladding refractive index. As a result, all-dielectric single-channel interferometers as modulators of only 33 m2 footprint and sensors with 19,200 2pirad/RIUcm sensitivity values are reported and validated by two different simulation methods. This work allows the design and optimization of slow light interferometers for different applications by considering several performance criteria, which can be extended to other photonic structures.

Expression and characterization of two recombinant mammalian metalloproteins : |b bovine microsomal cytochrome b₅ and human serum transferrin (N lobe)
Creators: name: Funk, Walter David
Publisher: name: University of British Columbia
Year: 2011

description: Two separate systems were developed for the expression of recombinant metalloproteins. A synthetic gene encoding the lipase-solubilized form of bovine liver microsomal cytochrome b₅ was designed and assembled for expression in E. coli. Analysis of the initial recombinant cytochrome revealed differences in several physical characteristics of the molecule compared to the authentic bovine liver species, including a reduction potential that was lower by 17 mV. Further studies showed the primary sequence of the initial recombinant differed from the authentic protein in the amidation status of three residues which, when corrected yielded a recombinant protein identical in behaviour to the authentic protein. The participation of Ser64 in the stabilization of the oxidized form of cytochrome b₅ was investigated using site-directed mutagenesis to alter this residue to Ala, which was predicted to ablate a hydrogen bond formed between the protein and heme-propionate 7. Spectroelectrochemical analysis of this variant showed that the reduction potential had been shifted downwards by 7 mV, in contrast to predictions from a structural model describing the red/ox behaviour of cytochrome b₅ (Argos and Mathews, 1975). The role of heme carboxylates in determining the reduction potential was confirmed for both the wild-type and Ala64 variants by heme replacement studies using the esterified derivative of protoporphyrin IX, suggesting that the presence of free carboxylates contributes to the stabilization of the oxidized species. In addition, constructions for the expression of the trypsin-solubilized form of bovine liver microsomal cytochrome b₅ and the erythrocytic form of human cytochrome b₅ are described. A tissue culture cell system was developed for the expression of the N-terminal half molecule of human serum transferrin. The recombinant molecule (hTF/2N) was secreted at high levels from selected eukaryotic cells, and displayed high identity with the proteolytically-derived molecule from authentic human serum transferrin as judged by sequence analysis, electrophoretic mobility and iron binding capacity. A construction for the expression of the C-terminal half molecule was assembled but failed to express recombinant protein when introduced into tissue culture cells. The production of these two heterologous expression systems allows for high-level recovery of recombinant protein and provides a convenient approach to structure-function studies employing site-directed mutagenesis techniques.

description: This paper is the first in a series whose goal is to develop a fundamentally new way of constructing theories of physics. The motivation comes from a desire to address certain deep issues that arise when contemplating quantum theories of space and time. Our basic contention is that constructing a theory of physics is equivalent to finding a representation in a topos of a certain formal language that is attached to the system. Classical physics arises when the topos is the category of sets. Other types of theory employ a different topos. In this paper we discuss two different types of language that can be attached to a system, S. The first is a propositional language, PL(S); the second is a higher-order, typed language L(S). Both languages provide deductive systems with an intuitionistic logic. The reason for introducing PL(S) is that, as shown in paper II of the series, it is the easiest way of understanding, and expanding on, the earlier work on topos theory and quantum physics. However, the main thrust of our programme utilises the more powerful language L(S) and its representation in an appropriate topos.

description: Specialized wheat farms—those with at least 50 percent of their production from wheat and with at least $40,000 in total production—fared worse in 1985 than other specialized crop farms. Specialized wheat farms had the lowest returns margin and return on assets of four grain specialties—wheat, corn, rice, and other small grains. Wheat farmers also relied more on off-farm income than other specialized grain farmers. The largest specialized wheat farms, those with production of $250,000 or more, had the best returns by all measures in 1985. Specialized wheat farms in the North Central and South Central regions were about equally strong in 1985. Those in the Northwest were the weakest because of their high cost structures and heavy debt burdens.
Isometric deformations of surfaces of translation

description: A \emph{surface of translation} is a sum $(u,v)\mapsto\gtα(u)+\gtβ(v)$ of two space curves: a \emph{path} $\gtα$ and a \emph{profile} $\gtβ$. A fundamental problem of differential geometry and shell theory is to determine the ways in which surfaces deform isometrically, i.e., by bending without stretching. Here, we explore how surfaces of translation bend. Existence conditions and closed-form expressions for special bendings of the infinitesimal and finite kinds are provided. In particular, all surfaces of translation admit a purely torsional infinitesimal bending. Surfaces of translation whose path and profile belong to an elliptic cone or to two planes but never to their intersection further admit a torsion-free infinitesimal bending. Should the planes be orthogonal, the infinitesimal bending can be integrated into a torsion-free (finite) bending. Surfaces of translation also admit a torsion-free bending if the path or profile has exactly two tangency directions. Throughout, smooth and piecewise smooth surfaces, i.e., surfaces with straight or curved creases, are invariably dealt with and some extra care is given to situations where the bendings cause new creases to emerge.
