description: Recently, Girolami and Adesso have demonstrated that the calculation of quantum discord for two-qubit case can be viewed as to solve a pair of transcendental equation (Phys. Rev. A, {\bf 83}, 052108(2011)). In present work, we introduce the generalized Choi-Jamiolkowski isomorphism and apply it as a convenient tool for constructing transcendental equations. For the general two-qubit case, we show that the transcendental equations always have a finite set of universal solutions, this result can be viewed as a generalization of the one get by Ali, Rau, and Alber (Phys. Rev. A, {\bf 81}, 042105 (2010)). For a subclass of $X$ state, we find the analytical solutions by solving the transcendental equations.

description: Abstract Aim: Over the past two decades, two catastrophic events caused a steep decline in health services in Liberia: the long-lasting civil war (1989-2003) and the weak response of the health system to the Ebola Viral Disease (EVD) outbreak (2013-2015). In early 2015 The Liberian Government reacted and developed a strategic health policy framework. This paper reviews that framework with a focus on maternal and newborn health. Methods: The study is designed as a narrative review executed during the second half of 2017 in Monrovia. It takes advantage of triangulation, derived from recent international and national documents, relevant literature, and available information from primary and secondary sources and databases. Results: In 2015 the severely compromised health system infrastructure included lack of functional refrigerators, low availability of vaccines and child immunization guidelines, high stock-out rates, and an absence of the cold chain minimum requirements in 46% of health facilities. The public health workforce on payroll during 2014/15 included only 117 physicians. Skilled birth attendance as an indicator of maternal health services performance was 61%. Presently, approximately 4.5 women die each day in Liberia due to complications of pregnancy, delivery, and during the post-partum period, equalling about 1,100 women per 100,000 live births. Of particular note is the adolescent birth rate of 147 per 1000 women aged 15-19 years, three times higher than the world average of 44. Additionally, with a neonatal mortality rate of 19.2 neonatal deaths per 1,000 live births, Liberia stands higher than the world average as well. The high mortality rates are caused by multiple factors, including a delay in recognition of complications and the need for medical care, the time it takes to reach a health facility due to a lack of suitable roads and transportation, and a delay in receiving competent care in the health facilities. Conclusions: The fact that performance is above average for some indicators and far below for other points to unexplained discrepancies and a mismatch of international and national definitions or validity of data. Therefore, it is recommended to concentrate on the core of tracer indicators adopted at the global level for Universal Health Coverage and the Sustainable Development Goals to enable a permanent update of relevant information for policymaking and adjustment. At present all health policy documents miss a thorough application of the SMART objectives (Specific, Measurable, Attainable, Relevant and Timely), notably missing in most documents are realistic and detailed budgeting and obligatory timelines for set targets.

Asexual morph: Unknown.
 Material examined:— THAILAND, Ranong, on unidentified dead wood, 5 October 2017; M. Zeng, ST05 (MFLU 18-0714, holotype); ibid. (HKAS 97492, isotype); THAILAND, Ron Thong, Prachuap Khiri Khan, on unidentified dead wood, 28 August 2017; C.G. Lin, 1-2 (MFLU 18-1329, HKAS 97489); ibid. 1-3 (MFLU 18-0712, HKAS 97490).
 Note: This species is characterized by red, sessile apothecia, reddish paraphyses and ornamented ascospores with gelatinous sheath. Phylogenetic results show a close relationship between P. hydei and P. carnicolor. But there are three major morphological differences between these two species: 1). Colors of apothecia: P. hydei has red apothecia (FIG. 2), but the apothecia of P. carnicolor shows distinct orange color (FIG. 4). 2). Shape of apothecia: P. hydei has sessile discoid apothecia (FIG. 2, h) and P. carnicolor has short stalked (FIG. 4, c), cupulate to irregular apothecia. 3). Colors of paraphyses: within the genus Phillipsia, content of paraphyses is a very important feature to identify (Hansen et al. 1999). We observed reddish paraphyses in P. hydei and yellowish paraphyses in P. carnicolor respectively.

description: We give a brief introduction to Hamiltonian optics and Lie algebraic methods. We use these methods to describe the operators governing light propagation, refraction and reflection in phase space. The method offers a systematic way to find aberration coefficients of any order for arbitrary rotationally symmetric optical systems. The coefficients from the Lie method are linked to the Seidel aberration coefficients. Furthermore, the property of summing individual surface contributions is preserved by the Lie algebraic theory. Three examples are given to validate the proposed methodology with good results.

Isoetes shangrilaensis

description: Isoetes shangrilaensis Xiang Li, Yuqian Huang, Xiaokang Dai & Xing Liu, sp. nov.
 Type: — China. Yunnan Province, Shangri-la 4, elevation 3305m, N 27°52′; E 99°44′, July 2003, X. Liu, WH2003080800 (holotype WH!).
 Diagnosis: — Isoetes shangrilaensis is similar to I. hypsophila, but different in both spore size and ornamentations: megaspore size (207.25–273.09 μm vs. 361.13–510.49 μm in I. hypsophila), megaspore morphology (tuberculate to rugulate megaspore vs. laevigate megaspore in I. hypsophila), and microspore morphology (echinate to cristate microspore vs. bacculate to rugulate microspore in I. hypsophila).
 Description: —Plants aquatic, submersed. Root stock 3-lobed. Leaves white basally, green above, spirally arranged, wide spreading, 28.51–178.42 mm long, ca. 1 mm wide at mid-length, in tufts of 12 to 20, flatted on upper side, rounded on lower sides, base alate; ligule triangular, cuspidate; velum rudimentary, covering only distal edge of sporangium. Sporangium basal, oval, ca 1.3–5.6 x 1.7–4.5 mm. Megaspores, 207.25–273.09 μm in diameter (mean 244.71 μm); proximal surface laevigate with some scurfy scales, globose in the polar view while less oblate in equatorial view; equatorial and radial ridges thin and smooth; distal surface low, sparsely tuberculate to rugulate but crowdedly covered with small fibrils. Microspores, 11.21–23.66 μm in length (mean 19.41 μm); proximal surface coarsely low echinate to cristate surface with occasional filamentous structures; proximal ridge not clear and without swellings perpendicular to it; distal surface similar as proximal surface, echinate to cristate.
 Distribution and habitat: — Isoetes shangrilaensis can be considered endemic to Shangri-la in Yunnan Province, and it is currently detected only in two localities, Xiajisha Country and Caishichang. The plants are submersed in the ponds. Isoetes shangrilaensis is a rare and endangered species in China. We have found only two sites in Shangri-la in Yunnan Province. Pollution continues to raise the risk of extinction for this species. The protection of two populations of this new species of Isoetes are crucial, and search for additional populations are urgently needed.
 Additional specimens examined: — China. Yunnan Province, Shangri-la, Xiajiasha country, elevation 3275m, N 27°28′; E 99°48′, July 2010, X. Liu, WH2010 (holotype WH!).

description: Globular clusters (GCs) associated with the Sagittarius dwarf spheroidal galaxy (Sgr dSph) have evolved under the gravitational potential of both Sgr dSph and the Milky Way. The effects of these potentials are most pronounced in the extra-tidal regions as compared to the central regions of the GCs.We aim to study the extra-tidal regions of the GCs that are possibly associated with Sgr dSph, namely Arp 2, Terzan 8, NGC 5634, NGC 6284, Terzan 7, NGC 2419, NGC 4147, M 54 and Pal 12, using data from the {\it Gaia} early data release 3. We selected the extra-tidal candidates based on their angular distances from the cluster centre in the RA-Dec plane, proper motions of the clusters and the individual extra-tidal star candidates, and their positions on the colour-magnitude diagrams of the clusters. We found extra-tidal candidates for the nine studied GCs. For eight of them, the surface density of candidate extra-tidal stars in the vicinity of the clusters is in significant excess with respect to more distant surrounding fields. No extended extra-tidal features beyond 5 tidal radii were detected for any of the clusters. We publish a list of the most probable extra-tidal candidates that we determined using Gaia astrometric and photometric data. Our analysis shows that the clusters that are associated with Sgr dSph are more likely affected by the gravitational potential of the Sgr, as the distribution of extra-tidal stars is elongated in the same direction as the local stream. NGC 4147 is the only exception. We found some high-probability candidate extra-tidal stars in several of the analysed clusters. We failed to detect any coherent large-scale tidal tail around them.

description: Use of hookah and little cigars/cigarillos (LCCs) is high among adolescents and young adults. Although these products have health effects similar to cigarettes, adolescents and young adults believe them to be safer. This study examined adolescent and young adult perceptions of hookah and LCCs to develop risk messages aimed at discouraging use among users and at-risk nonusers. Ten focus groups with 77 adolescents and young adults were conducted to explore their perceptions about the perceived risks and benefits of hookah and LCC use. Participants were users of other (non-cigarette) tobacco products (n=47) and susceptible nonusers (n=30). Transcripts were coded for emergent themes on participants’ perceptions of hookah and LCCs. Participants did not perceive health effects associated with hookah and LCC use to be serious or likely to happen given their infrequency of use and perceptions that they are less harmful than cigarettes. Participants generally had positive associations with smoking hookah and LCCs for several reasons, including that they are used in social gatherings, come in various flavors, and can be used to perform smoke tricks. Because adolescents and young adults underestimate and discount the long-term risks associated with hookah and LCC use, effective messages may be those that focus on the acute/immediate health and cosmetic effects.

description: The presence of superconducting and superfluid components in the core of mature neutron stars calls for the rethinking of a number of key magnetohydrodynamical notions like resistivity, the induction equation, magnetic energy and flux-freezing. Using a multi-fluid magnetohydrodynamics formalism, we investigate how the magnetic field evolution is modified when neutron star matter is composed of superfluid neutrons, type-II superconducting protons and relativistic electrons. As an application of this framework, we derive an induction equation where the resistive coupling originates from the mutual friction between the electrons and the vortex/fluxtube arrays of the neutron and proton condensates. The resulting induction equation allows the identification of two timescales that are significantly different from those of standard magnetohydrodynamics. The astrophysical implications of these results are briefly discussed.

description: A new mechanism of particle acceleration, based on the resonant interaction of a classical electromagnetic wave (EM) with a quantum wave (associated with a relativistic particle), is explored. In a model illustrative calculation, we study the fate of a Klein Gordon wave subjected to the intense radio frequency waves generated in the vicinity of an active galactic nuclei (AGN). In the framework of the paper we examine a quantum wave associated with a relativistic particle, and it is shown that the group velocity of the wave approaches the speed of light, implying that the particles resonantly exchange energy with EM waves, eventually leading to acceleration of particles to very high energies. For typical parameters of under accreting Eddington radio AGN, it is shown that the resonant energization could catapult particles to extreme energies $\sim 10^{16-20}$eV.

description: We study the Josephson effect in planar $SF_1F_2S$ junctions that consist of conventional $s$-wave superconductors ($S$) connected by two metallic monodomain ferromagnets ($F_1$ and $F_2$) with arbitrary transparency of interfaces. We solve the scattering problem in the clean limit based on the Bogoliubov-de Gennes equation for both spin-singlet and odd in frequency spin-triplet pairing correlations. We calculate numerically the Josephson current-phase relation $I(ϕ)$. While the first harmonic of $I(ϕ)$ is completely generated by spin-singlet and short-range spin-triplet superconducting correlations, for noncollinear magnetizations of ferromagnetic layers the second harmonic has an additional long-range spin-triplet component. Therefore, for strong ferromagnetic influence, the long-range spin-triplet contribution to the second harmonic dominates. We find an exception due to the geometric resonance for equal ferromagnetic layers when the first harmonic is strongly enhanced. Both first and second harmonic amplitudes oscillate with ferromagnetic layer thicknesses due to $0-π$ transitions. We study the influence of interface transparencies and find additional resonances for finite transparency of interface between ferromagnetic layers.

description: We present the complete sample of protoplanetary disks from the Gemini- Large Imaging with GPI Herbig/T-tauri Survey (Gemini-LIGHTS) which observed bright Herbig Ae/Be stars and T-Tauri stars in near-infrared polarized light to search for signatures of disk evolution and ongoing planet formation. The 44 targets were chosen based on their near- and mid-infrared colors, with roughly equal numbers of transitional, pre-transitional, and full disks. Our approach explicitly did not favor well-known, "famous" disks or those observed by ALMA, resulting in a less-biased sample suitable to probe the major stages of disk evolution during planet formation. Our optimized data reduction allowed polarized flux as low as 0.002% of the stellar light to be detected, and we report polarized scattered light around 80% of our targets. We detected point-like companions for 47% of the targets, including 3 brown dwarfs (2 confirmed, 1 new), and a new super-Jupiter mass candidate around V1295 Aql. We searched for correlations between the polarized flux and system parameters, finding a few clear trends: presence of a companion drastically reduces the polarized flux levels, far-IR excess correlates with polarized flux for non-binary systems, and systems hosting disks with ring structures have stellar masses $<$ 3 Msun. Our sample also included four hot, dusty "FS CMa" systems and we detected large-scale ($>100$ au) scattered light around each, signs of extreme youth for these enigmatic systems. Science-ready images are publicly available through multiple distribution channels using a new FITS file standard jointly developed with members of the VLT/SPHERE team.

description: Little is known about factors associated with receipt of medication information among arthritis patients. This study explores information source receipt and associations between demographic and clinical/patient characteristics and the amount of arthritis medication information patients receive. Adult patients with osteoarthritis (OA) or rheumatoid (RA) arthritis (n = 328) completed an online cross-sectional survey. Patients reported demographic and clinical/patient characteristics and the amount of arthritis medication information received from 15 information sources. Bivariate and multivariable linear regression analyses were used to investigate whether those characteristics were associated with the amount of medication information patients received. Arthritis patients received the most information from health professionals followed by printed materials, media sources, and interpersonal sources. Greater receipt of information was associated with greater medication adherence, taking more medications, greater medication-taking concerns, more satisfaction with doctor medication-related support, and Black compared to White race. RA patients reported receiving more information compared to OA patients, and differences were found between RA patients and OA patients in characteristics associated with more information receipt. In conclusion, arthritis patients received the most medication information from professional sources, and both positive (e.g., greater satisfaction with doctor support) and negative (e.g., more medication taking concerns) characteristics were associated with receiving more medication information.

description: We study the cusped Wilson line operators and Bremsstrahlung functions associated to particles transforming in the rank-$k$ symmetric representation of the gauge group $U(N)$ for ${\cal N} = 4$ super Yang-Mills. We find the holographic D3-brane description for Wilson loops with internal cusps in two different limits: small cusp angle and $k\sqrtλ\gg N$. This allows for a non-trivial check of a conjectured relation between the Bremsstrahlung function and the expectation value of the 1/2 BPS circular loop in the case of a representation other than the fundamental. Moreover, we observe that in the limit of $k\gg N$, the cusped Wilson line expectation value is simply given by the exponential of the 1-loop diagram. Using group theory arguments, this eikonal exponentiation is conjectured to take place for all Wilson loop operators in symmetric representations with large $k$, independently of the contour on which they are supported.

description: The coherent $η$ meson energy $E_η$ distribution spectra in the proton nucleus reaction have been calculated to investigate the $π^0 - η$ mesons' interference, in addition to the study of resonance $N^*$ dynamics in the nucleus. The elementary reaction occurring in the nucleus is assumed to proceed as $ pN \to pN^* $; $ N^* \to Nη$. Born terms in the intermediate state is also considered. In a scalar-isovector nucleus, this reaction occurs because of $π^0$ and $η$ meson exchange interactions for the forward going proton and $η$ meson; other meson exchange potentials do not contribute in this process. The sensitivity of the cross section to the hadron nucleus interactions, and the beam energy dependence of the cross section are studied for this reaction.

description: In the current state of cosmology, where cosmological parameters are being measured to percent accuracy, it is essential to understand all sources of error to high precision. In this paper we present the results of a study of the local variations in the Hubble constant measured at the distance scale of the Coma Cluster, and test the validity of correcting for the peculiar velocities predicted by gravitational instability theory. The study is based on N-body simulations, and includes models featuring a coupling between dark energy and dark matter, as well as two $Λ$CDM simulations with different values of $σ_8$. It is found that the variance in the local flows is significantly larger in the coupled models, which increases the uncertainty in the local measurements of the Hubble constant in these scenarios. By comparing the results from the different simulations, it is found that most of the effect is caused by the higher value of $σ_8$ in the coupled cosmologies, though this cannot account for all of the additional variance. Given the discrepancy between different estimates of the Hubble constant in the universe today, cosmological models causing a greater cosmic variance is something that we should be aware of.

description: Recent observations with the GISMO (Goddard-IRAM Superconducting 2 Millimeter Observer) 2 mm camera revealed a detection 8 arcsec away from the lensed galaxy MACS1149-JD1 at z=9.6. Within the 17.5 arcsec FWHM GISMO beam, this detection is consistent with the position of the high-redshift galaxy and therefore, if confirmed, this object could be claimed to be the youngest galaxy producing significant quantities of dust. We present higher resolution (8.5 arcsec) observations of this system taken with the AzTEC 1.1 mm camera mounted on the Large Millimeter Telescope Alfonso Serrano. Dust continuum emission at the position of MACS1149-JD1 is not detected with an r.m.s. of 0.17 mJy/beam. However, we find a detection ~ 11 arcsec away from MACS1149-JD1, still within the GISMO beam which is consistent with an association to the GISMO source. Combining the AzTEC and GISMO photometry, together with Herschel ancillary data, we derive a z_phot= 0.7-1.6 for the dusty galaxy. We conclude therefore that the GISMO and AzTEC detections are not associated with MACS1149-JD1. From the non-detection of MACS1149-JD1 we derive the following (3 σ) upper limits corrected for gravitational lensing magnification and for cosmic microwave background effects: dust mass < 1.6 x 10^7 M_sun, IR luminosity < 8 x 10^10 L_sun, star formation rate < 14 M_sun/yr, and UV attenuation < 2.7 mag. These limits are comparable to those derived for other high-redshift galaxies from deep Atacama Large Millimeter/submillimeter Array (ALMA) observations.

description: In this letter, we present recent observations from the Hubble Space Telescope of the interacting transient, SN 2016jbu, at +5 years. We find no evidence for any additional outburst from SN 2016jbu, and the optical source has now faded significantly below the progenitor magnitudes from early 2016. Similar to recent observations of SN 2009ip and SN 2015bh, SN 2016jbu has not undergone a significant change in colour over the past 2 years, suggesting that there is a lack of on-going dust formation. We find SN 2016jbu is fading slower than that expected from radioactive nickel, but faster than the decay of SN 2009ip. The late time light curve displays a non-linear decline and follows on from a re-brightening event that occurred $\sim$8 months after peak brightness, suggesting CSM interaction continues to dominate SN 2016jbu. While our optical observations are plausibly consistent with a surviving, hot, dust-enshrouded star, this would require an implausibly large dust mass. These new observations suggest that SN 2016jbu is a genuine, albeit strange, supernova, and we discuss the plausibility of a surviving binary companion.

description: We conducted a spectral and temporal analysis of X-ray data from the Be X-ray binary pulsar SXP 15.6 located in the Small Magellanic Cloud based on NuSTAR, NICER and Swift observations during the 2021 outburst. We present for the first time the broadband X-ray spectra of the system based on simultaneous NuSTAR and NICER observations. Moreover we use monitoring data to study the spectral and temporal properties of the system during the outburst. Comparison of the evolution of the 2021 outburst with archival data reveals a consistent pattern of variability with multiple peaks occurring at time intervals similar to the orbital period of the system (~36 d). Our spectral analysis indicates that most of the energy is released at high energies above 10 keV while we found no cyclotron absorption line in the spectrum. Analysis of the spectral evolution during the outburst, we find that the spectrum is softer-when-brighter, which in turn reveals that the system is probably in the super-critical regime where the accretion column is formed. This places an upper limit to the magnetic field of the system of the order of 7$\times$10$^{11}$ G. The spin-evolution of the neutron star (NS) during the outburst is consistent with an NS with a low magnetic field ($\sim{5}\times$10$^{11}$ G), while there is evident orbital modulation which we modelled and derived the orbital parameters. We found the orbit to have a moderate eccentricity of ~0.3. Our estimates of the magnetic field are consistent with the lack of an electron cyclotron resonance scattering feature in the broadband X-ray spectrum.

description: The Obama administration has confronted a formidable array of obstacles in implementing the Affordable Care Act (ACA). The ACA has overcome those obstacles to substantially expand access to health insurance, though significant problems with its approach have emerged. What does the ACA's performance to date tell us about the possibilities and limits of health care reform in the United States? I identify key challenges in ACA implementation-the inherently disruptive nature of reform, partisan polarization, the limits of "near universal" coverage, complexity, and divided public opinion-and analyze how these issues have shaped its evolution. The article concludes by exploring the political and policy challenges that lie ahead for the ACA.

description: Patients with chronic liver disease and cirrhosis have a dysregulated coagulation system and are prone to thrombosis. The basis for this hypercoagulable state is not completely understood. Tissue factor (TF) is the primary initiator of coagulation in vivo. Patients with cirrhosis have increased TF activity in white blood cells and circulating microparticles. The aim of our study was to determine the contribution of TF to the hypercoagulable state in a mouse model of chronic liver injury.

description: We present theoretical and experimental investigations of the magnetism of paramagnetic semiconductor CdSe:Mn nanocrystals and propose an efficient approach to the exposure and analysis of the underlying anti-ferromagnetic interactions between magnetic ions therein. A key advance made here is the build-up of an analysis method with the exploitation of group theory technique that allows us to distinguish the anti-ferromagnetic interactions between aggregative Mn2+ ions from the overall pronounced paramagnetism of magnetic ion doped semiconductor nanocrystals. By using the method, we clearly reveal and identify the signatures of anti-ferromagnetism from the measured temperature dependent magnetisms, and furthermore determine the average number of Mn2+ ions and the fraction of aggregative ones in the measured CdSe:Mn nanocrystals.

description: Because of global epidemics of obesity and type 2 diabetes, the prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing both in Europe and the United States, becoming one of the most frequent causes of chronic liver disease and predictably, one of the leading causes of liver transplantation both for end-stage liver disease and hepatocellular carcinoma. For most transplant teams around the world this will raise many challenges in terms of preand post-transplant management. Here we review the multifaceted impact of NAFLD on liver transplantation and will discuss: (1) NAFLD as a frequent cause of cryptogenic cirrhosis, end-stage chronic liver disease, and hepatocellular carcinoma; (2) prevalence of NAFLD as an indication for liver transplantation both in Europe and the United States; (3) the impact of NAFLD on the donor pool; (4) the access of NAFLD patients to liver transplantation and their management on the waiting list in regard to metabolic, renal and vascular comorbidities; (5) the prevalence and consequences of post-transplant metabolic syndrome, recurrent and de novo NAFLD; (6) the alternative management and therapeutic options to improve the long-term outcomes with particular emphasis on the correction and control of metabolic comorbidities.

description: [“Gaetano’s Destiny”. Narrative suggestions on the subject of digital hate] Despite being a decidedly long-standing and controversial phenomenon, in recent times, hate speech has reappeared forcefully in the limelight, also due to the increased virulence conferred on it by the encounter with the Internet and – in particular – with Social Networks. Hence the need to reflect again on the issue of hate speech, in order to outline its contours, to underline its peculiarities and to envisage possible prevention and contrast strategies.

description: W-CDF-S, ELAIS-S1, and XMM-LSS will be three Deep-Drilling Fields (DDFs) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), but their extensive multi-wavelength data have not been fully utilized as done in the COSMOS field, another LSST DDF. To prepare for future science, we fit source spectral energy distributions (SEDs) from X-ray to far-infrared in these three fields mainly to derive galaxy stellar masses and star-formation rates. We use CIGALE v2022.0, a code that has been regularly developed and evaluated, for the SED fitting. Our catalog includes 0.8 million sources covering $4.9~\mathrm{deg^2}$ in W-CDF-S, 0.8 million sources covering $3.4~\mathrm{deg^2}$ in ELAIS-S1, and 1.2 million sources covering $4.9~\mathrm{deg^2}$ in XMM-LSS. Besides fitting normal galaxies, we also select candidates that may host active galactic nuclei (AGNs) or are experiencing recent star-formation variations and use models specifically designed for these sources to fit their SEDs; this increases the utility of our catalog for various projects in the future. We calibrate our measurements by comparison with those in well-studied smaller regions and briefly discuss the implications of our results. We also perform detailed tests of the completeness and purity of SED-selected AGNs. Our data can be retrieved from a public website.

description: We examine how disordering joint position influences the linear elastic behavior of lattice materials via numerical simulations in two-dimensional beam networks. Three distinct initial crystalline geometries are selected as representative of mechanically isotropic materials low connectivity, mechanically isotropic materials with high connectivity, and mechanically anisotropic materials with intermediate connectivity. Introducing disorder generates spatial fluctuations in the elasticity tensor at the local (joint) scale. Proper coarse-graining reveals a well-defined continuum-level scale elasticity tensor. Increasing disorder aids in making initially anisotropic materials more isotropic. The disorder impact on the material stiffness depends on the lattice connectivity: Increasing the disorder softens lattices with high connectivity and stiffens those with low connectivity, without modifying the scaling between elastic modulus and density (linear scaling for high connectivity and cubic scaling for low connectivity). Introducing disorder in lattices with intermediate fixed connectivity reveals both scaling: the linear scaling occurs for low density, the cubic one at high density, and the crossover density increases with disorder. Contrary to classical formulations, this work demonstrates that connectivity is not the sole parameter governing elastic modulus scaling. It offers a promising route to access novel mechanical properties in lattice materials via disordering the architectures.
