description: As part of our search for compounds with cytotoxicity from endophytes of traditional Chinese medicines, two novel nor-sesquiterpenoids (1–2) with a new skeleton containing a tetrahydrofuran moiety were isolated form a rice medium of Fusarium tricinctum, an endophytic fungus isolated from the root of Ligusticum chuanxiong. The structures of these two previously undescribed compounds were elucidated by interpretation of the spectroscopic evidences including NMR correlations as well as MS data. The absolute configurations of these two compounds were confirmed by TD-DFT-ECD calculations. An MTT assay indicated that compound 1 exhibited moderate cytotoxic activity against MV4-11 with an IC50 value of 22.29 μM.

description: Abstract: We discuss an approach to gravitational waves based on Geometric Algebra and Gauge Theory Gravity. After a brief introduction to Geometric Algebra (GA), we consider Gauge Theory Gravity, which uses symmetries expressed within the GA of flat spacetime to derive gravitational forces as the gauge forces corresponding to making these symmetries local. We then consider solutions for black holes and plane gravitational waves in this approach, noting the simplicity that GA affords in both writing the solutions, and checking some of their properties. We then go on to show that a preferred gauge emerges for gravitational plane waves, in which a ‘memory effect’ corresponding to non-zero velocities left after the passage of the waves becomes clear, and the physical nature of this effect is demonstrated. In a final section we present the mathematical details of the gravitational wave treatment in GA, and link it with other approaches to exact waves in the literature. Even for those not reaching it via Geometric Algebra, we recommend that the general relativity metric-based version of the preferred gauge, the Brinkmann metric, be considered for use more widely by astrophysicists and others for the study of gravitational plane waves. These advantages are shown to extend to a treatment of joint gravitational and electromagnetic plane waves, and in a final subsection, we use the exact solutions found for particle motion in exact impulsive gravitational waves to discuss whether backward in time motion can be induced by strongly non-linear waves.

description: Bulk LiOsO3 was experimentally identified as a "ferroelectric" metal where polar distortions coexist with metallicity [Shi et al., Nature Materials 12, 1024 (2013)]. It is generally believed that polar displacements in a "ferroelectric" metal cannot be switched by an external electric field. Here, via comprehensive density functional theory calculations, we demonstrate that a two-unit-cell-thick LiOsO3 thin film exhibits a ferroelectric ground state having an out-of-plane electric dipole moment that can be switched by an external electric field. Moreover, its dipole moment-versus-electric-field hysteresis loop is asymmetric because only surface Li ions'displacements are reversed by external electric field whereas the field-induced force on inner Li atoms are nearly fully screened by itinerant electrons. As a relevant by-product of our study, we also extend the concept of "Born effective charge" to finite metallic systems, and show its usefulness to rationalize the observed effects.

description: Palliative care in Indonesia is problematic because of cultural and socio-economic factors. Family in Indonesia is an integral part of caregiving process in inpatient and outpatient settings. However, most families are not adequately prepared to deliver basic care for their sick family member. This research is a pilot project aiming to evaluate how basic skills training (BST) given to family caregivers could enhance the quality of life (QoL) of palliative care cancer patients in Indonesia. The study is a prospective quantitative with pre and post-test design. Thirty family caregivers of cancer patients were trained in basic skills including showering, washing hair, assisting for fecal and urinary elimination and oral care, as well as feeding at bedside. Patients’ QoL were measured at baseline and 4 weeks after training using EORTC QLQ C30. Hypothesis testing was done using related samples Wilcoxon Signed Rank. A paired t-test and one-way ANOVA were used to check in which subgroups was the intervention more significant. The intervention showed a significant change in patients’ global health status/QoL, emotional and social functioning, pain, fatigue, dyspnea, insomnia, appetite loss, constipation and financial hardship of the patients. Male patient’s had a significant effect on global health status (qol) (p = 0.030); female patients had a significant effect on dyspnea (p = 0.050) and constipation (p = 0.038). Younger patients had a significant effect in global health status/ QoL (p = 0.002). Patients between 45 and 54 years old had significant effect on financial issue (p = 0.039). Caregivers between 45 and 54 years old had significant effect on patients’ dyspnea (p = 0.031). Thus, it is concluded that basic skills training for family caregivers provided some changes in some aspects of QoL of palliative cancer patients. The intervention showed promises in maintaining the QoL of cancer patients considering socioeconomic
and cultural challenges in the provision of palliative care in Indonesia.

description: A novel highly oxygenated norbisabolane sesquiterpene, namely phyllanthacidoid U (1), along with nine known sesquiterpenes (2–10) was isolated from the roots and stems of Phyllanthus acidus (L.) Skeels (Phyllanthaceae), collected from Xishuangbanna, Yunnan province, China. Their structures were elucidated by means of extensive spectroscopic analysis and by comparison of their data with reported values in literatures. Instead of the C-13 ester O-glycosyl found mostly in the titled plant growing in Thailand, compound 1 possessed a rare N-β-glucosamine-2-N-acetate moiety linked directly to the carbonyl at C-13 through an amido bond. Moreover, the acyl group at C-10 in 1 was (Z)-2-(2-hydroxyethyl)-pent-2-enedioyl group, instead of benzoic or p-hydroxybenzoic moieties found commonly in the reported norbisabolane sesquiterpenes. The known sesquiterpene 5 displayed stronger anti hepatitis B virus (HBV) activity with IC50 values of 1.69 ± 0.22 and 2.79 ± 0.69 μM towards HBV surface antigen (HBsAg) and HBV excreted antigen (HBeAg) secretion, respectively.

description: Gemeinschaftliches Wohnen und selbstorganisiertes Bauen bieten neue Antworten auf die aktuellen Herausforderungen im Wohnungswesen. Seit vielen Jahren haben Baugruppen und Hausprojekte in zahlreichen Ländern Erfahrungen der gemeinschaftlichen Planung gesammelt, neue Wohnformate entwickelt und verschiedene Formen des gemeinschaftlichen Wohnens erprobt, die über das Wohnen wie gewohnt hinausreichen. Unsere besondere Aufmerksamkeit gilt Wohnprojekten, die mit selbstorganisierten Planungsprozessen, einer nicht gewinnorientierten Bewirtschaftungsorientierung und kollektiver Verantwortung gemeinschaftliche Wohnformen entwickeln und nutzen. Diese Projekte reagieren damit auf eine doppelte Krise des Wohnens: Zum einen bieten sie Antworten für neue gesellschaftliche Anforderungen, die in den klassischen Familienwohnungen der Moderne nur unzureichend bedient werden können, zum anderen durchbrechen sie die immobilienwirtschaftliche Verwertungslogik, die ökonomischen Gewinn über das Wohnen als Grundbedürfnis und unabdingbares Recht stellen.

description: Mountain areas are very often considered to be biodiversity hotspots. Rocks are one of the most unique habitats and serve as a suitable biotope for many endemic and specialized plant species. Here we present the results of the vegetation studies conducted in central and eastern Pamir-Alai and the south-western Tian Shan mountains in 2013‒2019. Based on 334 phytosociological relevés we propose a synopsis of the rock communities of the montane and colline zones of eastern Middle Asia. As a result of our research, we distinguish 17 communities defined into five groups of petrophytic vegetation within the Caricion koshewnikowii alliance. We describe 11 new associations: Feruletum bucharicae, Scrophularietum glabellae, Asperulo albiflorae–Kafirniganietum hissaricae, Scutellarietum immaculatae, Campanuletum eugeniae, Silenetum kuschakewiczii, Rosularietum platyphyllae, Spireaetum pilosae, Silenetum lithophilae, Campanuletum albertii, and Rhinactinidietum limoniifoliae. Distinctiveness of environmental conditions together with the species composition of the phytocoenoses within the montane and colline belts of eastern Middle and Central Asia make the investigated vegetation among those with the highest specific diversity and richness of endemisms in the whole area. The main factors that determine the species composition of the investigated vegetation seem to be phytogeography, altitude, bedrock type, and exposition.

description: Vascular endothelial growth factor-A (VEGF-A) has been observed as the predominant angiogenic factor in colorectal cancer (CRC) and the assessment of microvessel density (MVD) has been used to quantify tumor neoangiogenesis. This study aimed to determine clinicopathological and prognostic significance of both angiogenic markers in the local CRC patients. We analyzed tissue samples obtained from 81 cases with CRC. VEGF-A expression and MVD counts were immunohistochemically detected using anti VEGF-A and CD31. The assessments of both markers were classified as low and high. Correlation between VEGF-A expression and MVD value and clinicopathological characteristics were examined using Chi-square test. The overall survival (OS) was plotted using the Kaplan-Meier method. The results indicated a high VEGF-A expression was found more frequently in the rectal location (P=0.042) and T4 tumors (P=0.041) compared to their counterparts. Older patients tended to show a higher MVD value compared to younger cases (P=0.062). In addition, survival analysis showed that males had a worse OS compared to females (P=0.029), and VEGF-A expression and MVD count did not correlate with patients’ survival. In conclusion, there were significant differences of VEGF-A expression according to tumor location and T invasion. Sex, but not angiogenic markers, had an influence on the survival of CRC patients.

description: We discuss the Padé approximation to the $ππ$ scattering amplitudes in 1--loop chiral perturbation theory. The approximation restores unitarity and can reproduce the correct resonance poles, but the approximation violates crossing symmetry and produce spurious poles on the complex $s$ plane and therefore plagues its predictions on physical quantities at quantitative level. However we find that one virtual state in the IJ=20 channel may have physical relevance.

description: Lange Zeit hatten in der ,offiziellen‘ Geschichte der Arbeiter*innenbewegung Genossenschaftsinitiativen und Selbsthilfeunternehmen nur eine marginale Rolle gespielt. Dabei war die Bandbreite solcher Aktivitäten enorm: Im frühen 20. Jahrhundert reichten sie von Konsumvereinen über Produktions- und Baugenossenschaften bis hin zu Versicherungsgesellschaften. Die Vorgeschichte des genossenschaftlichen Wohnungsbaus speist sich aus sehr unterschiedlichen Ideologien und sozialreformerischen Praktiken. Man denke nur an die experimentellen Projekte der sogenannten utopischen Sozialisten oder an die Siedlungsvorhaben bürgerlicher Philanthropen (altgriechisch: Menschenfreund). Die Übertragung des Gedankens der Selbsthilfe auf die Wohnraumbeschaffung erweist sich als ausgesprochen schwierig, denn die speziellen Eigenschaften der Wohnungsproduktion (Langlebigkeit, komplizierte planerische Erschließung, hohe Finanzierungskosten) erschweren bzw. verunmöglichen Versuche einer genossenschaftlichen Selbsthilfe aus den Reihen der Arbeiterschaft. Der Aufstieg der Wohnungsbaugenossenschaften im späten 19. Jahrhundert zeichnet sich deshalb durch zwei Besonderheiten aus: Entweder handelte es sich um reine Mittelstandprojekte oder sie wurden von externen Finanzhilfen abgestützt, die mit speziellen Vorgaben verbunden waren (vgl. Novy/Prinz 1985: 12ff.).

description: Inclusion of inverse Compton effects in the calculation of deuterium-deuterium burn under the extreme conditions considered by Eliezer et al. [Phys. Lett. A 243 (1998) 298] are shown to decrease the maximum burn temperature from about 300 keV to only 100--150 keV. This decrease is such that tritium breeding by the DD --> T + p reaction is not sufficient to replace the small amount of tritium that is initially added to the deuterium plasma in order to trigger ignition at less than 10 keV.

Rate-Memory Trade-off for Multi-access Coded Caching with Uncoded Placement

description: We study a multi-access variant of the popular coded caching framework, which consists of a central server with a catalog of $N$ files, $K$ caches with limited memory $M$, and $K$ users such that each user has access to $L$ consecutive caches with a cyclic wrap-around and requests one file from the central server's catalog. The server assists in file delivery by transmitting a message of size $R$ over a shared error-free link and the goal is to characterize the optimal rate-memory trade-off. This setup was studied previously by Hachem et al., where an achievable rate and an information-theoretic lower bound were derived. However, the multiplicative gap between them was shown to scale linearly with the access degree $L$ and thus order-optimality could not be established. A series of recent works have used a natural mapping of the coded caching problem to the well-known index coding problem to derive tighter characterizations of the optimal rate-memory trade-off under the additional assumption that the caches store uncoded content. We follow a similar strategy for the multi-access framework and provide new bounds for the optimal rate-memory trade-off $R^*(M)$ over all uncoded placement policies. In particular, we derive a new achievable rate for any $L \ge 1$ and a new lower bound, which works for any uncoded placement policy and $L \ge K/2$. We then establish that the (multiplicative) gap between the new achievable rate and the lower bound is at most $2$ independent of all parameters, thus establishing an order-optimal characterization of $R^*(M)$ for any $L\ge K/2$. This is a significant improvement over the previously known gap result, albeit under the restriction of uncoded placement policies. Finally, we also characterize $R^*(M)$ exactly for a few special cases.

description: The current $\sim3.5σ$ discrepancy between the experimental measurement and theoretical prediction of the muon magnetic anomaly, $a_μ$, stands as a potential indication of the existence of new physics. The Muon $g-2$ experiment at Fermilab is set to measure $a_μ$ with a four-fold improvement in the uncertainty with respect to previous experiment, with an aim to determine whether the $g-2$ discrepancy is well established. The experiment recently completed its first physics run and a summer programme of essential upgrades, before continuing on with its experimental programme. The Run-1 data alone are expected to yield a statistical uncertainty of 350 ppb and the publication of the first result is expected in late-2019.

description: This paper investigates investment and output dynamics in a simple continuous time setting, showing that financing constraints substantially alter the relationship between net worth and the decisions of an optimizing firm. In the absence of financing constraints, net worth is irrelevant (the 1958 Modigliani−Miller irrelevance proposition applies). When incorporating financing constraints, a decline in net worth leads to the firm reducing investment and also output (when this reduces risk exposure). This negative relationship between net worth and investment has already been examined in the literature. The contribution here is providing new intuitive insights: (i) showing how large and long lasting the resulting non-linearity of firm behaviour can be, even with linear production and preferences; and (ii) highlighting the economic mechanisms involved—the emergence of shadow prices creating both corporate prudential saving and induced risk aversion. The emergence of such pronounced non-linearity, even with linear production and preference functions, suggests that financing constraints can have a major impact on investment and output; and this should be allowed for in empirical modelling of economic and financial crises (for example, the great depression of the 1930s, the global financial crisis of 2007−2008 and the crash following the Covid-19 pandemic of 2020).

description: Lithium, a prototypical simple metal under ambient conditions, has a surprisingly rich phase diagram under pressure, taking up several structures with reduced symmetry, low coordination numbers, and even semiconducting character with increasing density. Using first-principles calculations, we demonstrate that some predicted high-pressure phases of elemental Li also host topological electronic structures. Beginning at 80 GPa and coincident with a transition to the Pbca phase, we find Li to be a Dirac nodal line semimetal. We further calculate that Li retains linearly-dispersive energy bands in subsequent predicted higher pressure phases, and that it exhibits a Lifshitz transition between two Cmca phases at 220 GPa. The Fd-3m phase at 500 GPa forms buckled honeycomb layers that give rise to a Dirac crossing 1 eV below the Fermi energy. The well-isolated topological nodes near the Fermi level in these phases result from increasing p-orbital character with density at the Fermi level, itself a consequence of rising 1s core wavefunction overlap, and a preference for nonsymmorphic symmetries in the crystal structures favored at these pressures. Our results provide evidence that under pressure, bulk 3D materials with light elements, or even pure elemental systems, can undergo topological phase transitions hosting nontrivial topological properties near the Fermi level with measurable consequences; and that, through pressure, we can access these novel phases in elemental lithium.

description: Abstract: Background: Histological grading of choroid plexus tumors (CPTs) remains the best prognostic tool to distinguish between aggressive choroid plexus carcinoma (CPC) and the more benign choroid plexus papilloma (CPP) or atypical choroid plexus papilloma (aCPP); however, these distinctions can be challenging. Standard treatment of CPC is very aggressive and often leads to severe damage to the young child’s brain. Therefore, it is crucial to distinguish between CPC and less aggressive entities (CPP or aCPP) to avoid unnecessary exposure of the young patient to neurotoxic therapy. To better stratify CPTs, we utilized DNA methylation (DNAm) to identify prognostic epigenetic biomarkers for CPCs. Methods: We obtained DNA methylation profiles of 34 CPTs using the HumanMethylation450 BeadChip from Illumina, and the data was analyzed using the Illumina Genome Studio analysis software. Validation of differentially methylated CpG sites chosen as biomarkers was performed using pyrosequencing analysis on additional 22 CPTs. Sensitivity testing of the CPC DNAm signature was performed on a replication cohort of 61 CPT tumors obtained from Neuropathology, University Hospital Münster, Germany. Results: Generated genome-wide DNAm profiles of CPTs showed significant differences in DNAm between CPCs and the CPPs or aCPPs. The prediction of clinical outcome could be improved by combining the DNAm profile with the mutational status of TP53. CPCs with homozygous TP53 mutations clustered as a group separate from those carrying a heterozygous TP53 mutation or CPCs with wild type TP53 (TP53-wt) and showed the worst survival outcome. Specific DNAm signatures for CPCs revealed AK1, PER2, and PLSCR4 as potential biomarkers for CPC that can be used to improve molecular stratification for diagnosis and treatment. Conclusions: We demonstrate that combining specific DNAm signature for CPCs with histological approaches better differentiate aggressive tumors from those that are not life threatening. These findings have important implications for future prognostic risk prediction in clinical disease management.

description: Eucalyptus pellita has been posited as a primary raw material in Indonesia due to its fast growth. In some areas, however, trees with heart rot were found. Thus, the wood with heart rot was analysed chemically both in sound (sapwood, outer heartwood, inner heartwood) and degraded parts (heart rot-affected wood/HRAW). The results revealed that there was a different trend in the wood chemical composition between bottom and centre parts. In bottom parts, wood with bigger diameter of heart rot, the slight changes in polysaccharides and lignin amounts was observed in HRAW compared to sound wood parts. On the contrary, comparatively high lignin and low polysaccharide levels in HRAW were measured in centre parts. HRAW was also characterized with high content of inorganic materials and high pH values but low in extractive content, mostly ethanol soluble extractives or its polar fraction. Increasing of phenolic contents was more pronounced in HRAW of lower part than that of upper of the stem. The difference trend of chemical composition between bottom and centre parts suggesting the cause of heart rot could be several wood degraders.

description: We construct Wigner's continuous spin representations of the Poincaré algebra for massless particles in higher dimensions. The states are labeled both by the length of a space-like translation vector and the Dynkin indices of the {\it short little group} $SO(d-3)$, where $d$ is the space-time dimension. Continuous spin representations are in one-to-one correspondence with representations of the short little group. We also demonstrate how combinations of the bosonic and fermionic representations form supermultiplets of the super-Poincaré algebra. If the light-cone translations are nilpotent, these representations become finite dimensional, but contain zero or negative norm states, and their supersymmetry algebra contains a central charge in four dimensions.

description: A hallmark of a plethora of intracellular signaling pathways is the spatial separation of activation and deactivation processes that potentially results in precipitous gradients of activated proteins. The classical Metabolic Control Analysis (MCA), which quantifies the influence of an individual process on a system variable as the control coefficient, cannot be applied to spatially separated protein networks. The present paper unravels the principles that govern the control over the fluxes and intermediate concentrations in spatially heterogeneous reaction networks. Our main results are two types of the control summation theorems. The first type is a non-trivial generalization of the classical theorems to systems with spatially and temporally varying concentrations. In this generalization, the process of diffusion, which enters as the result of spatial concentration gradients, plays a role similar to other processes such as chemical reactions and membrane transport. The second summation theorem is completely novel. It states that the control by the membrane transport, the diffusion control coefficient multiplied by two, and a newly introduced control coefficient associated with changes in the spatial size of a system (e.g., cell), all add up to one and zero for the control over flux and concentration. Using a simple example of a kinase/phosphatase system in a spherical cell, we speculate that unless active mechanisms of intracellular transport are involved, the threshold cell size is limited by the diffusion control, when it is beginning to exceed the spatial control coefficient significantly.

description: Breast cancer cells with overexpression of HER2 are known to be more aggressive, invasive, and resistant to chemotherapeutic agent. Brazilin, the major compound in the Caesalpinia sappan L. (CS) heartwood, has been studied for it's anticancer activity. The purpose of this study was to investigate the cytotoxic and antimigratory activity of brazilin (Bi) in combination with doxorubicin (Dox) on MCF-7/HER2 cells. Cytotoxic activities of Bi individually and in combination with Dox were examined by MTT assay. Synergistic effects were analyzed by combination index (CI). Apoptosis and cell cycle profiles were observed by using flow cytometry. Migrating and invading cells were observed by using a Boyden chamber assay. Levels of MMP2 and MMP9 activity were observed by using a gelatin zymography assay. Levels of HER2, Bcl-2, Rac1, and p120 protein expression were observed by using an immunoblotting assay. The results of the MTT assay showed that Bi inhibited MCF-7/HER2 cell growth in a dose-dependent manner with an IC50 of 54 ± 3.7 μM. Furthermore, the combination of Bi and Dox showed a synergistic effect (CI <1). Flow cytometric analysis of Bi and its combination with Dox showed cellular accumulation in the G2/M phase and induction of apoptosis through suppression of Bcl-2 protein expression. In the Boyden chamber assay, gelatin zymography, and subsequent immunoblotting assay, the combination Bi and Dox inhibited migration, possibly through down regulation of MMP9, MMP2, HER2, Rac1, and p120 protein expression. Hence, it was deduced that Bi enhanced cytotoxic activity of Dox and inhibited migration of MCF-7/HER2 cells. Therefore, it is believed that it has strong potential to be developed for the treatment of metastatic breast cancer with HER2 overexpression.

description: This study „estimates the magnitude of the effect of the increase in groundfish imports on U.S. groundfish prices. The estimate is based on an analysis of the changes in supply and demand in the U.S. landings market. The short-run was found to be perfectly inelastic; changes in supply are therefore equal to changes in landings. The singleequation model was used to estimate several demand equations for the wholesale level and the implications for the landings level were derived. The following demand equation gave the best fit: log Qfsp = -.61 -.46 log II!2.12 (.17) Pm&p *Significant at 0.05 level **Significant at 0.01 level .26 log Y .044 D1** (.26) (.012) R 2 (Adjusted) =95.7 Durbin-Watson d = 1.83 .013 D 2 t** .003) The conclusions of the study are: 1. The decline of U.S. groundfish prices in the 1950Ts resulted from two factors: the drop in meat and poultry prices and the increase In imports, with the latter causing prices to drop by less than 8.1 percent. 2. The effects of imports on U.S. groundfish prices have been grossly overestimated in a recent study by the U.S. Bureau of Commercial Fisheries.

description: The two-flavor color superconductivity is studied over a wide range of baryon density with a single model. We pay a special attention to the spatial-momentum dependence of the gap and to the spatial-structure of Cooper pairs. At extremely high baryon density (O(10^{10} rho_0) with rho_0 being the normal nuclear matter density), our model becomes equivalent to the usual perturbative QCD treatment and the gap is shown to have a sharp peak near the Fermi surface due to the weak-coupling nature of QCD. On the other hand, the gap is a smooth function of the momentum at lower densities (O(10 rho_0)) due to strong color magnetic and electric interactions. To study the structural change of Cooper pairs from high density to lower density, quark correlation in the color superconductor is studied both in the momentum space and in the coordinate space. The size of the Cooper pair is shown to become comparable to the averaged inter-quark distance at low densities. Also, effects of the momentum-dependent running coupling and the antiquark pairing, which are both small at high density, are shown to be non-negligible at low densities. These features are highly contrasted to the standard BCS superconductivity in metals.

description: We demonstrate that the previously identified L/T transition brown dwarf SDSS J213154.43-011939.3 (SDSS 2131-0119) is a widely separated (82.3'', $\sim$3830 au) common proper motion companion to the low-mass star NLTT 51469, which we reveal to be a close binary itself, separated by 0.64''$\pm$0.01'' ($\sim$30 au). We find the proper motion of SDSS 2131-0119 of $μ_α\cosδ=-100\pm20$, $μ_δ=-230\pm20$ mas/yr consistent with the proper motion of the primary provided by Gaia DR2: $μ_α\cosδ=-95.49\pm0.96$, $μ_δ=-239.38\pm0.96$ mas/yr. Based on optical and near-infrared spectroscopy we classify NLTT 51469A as a M3$\pm$1 dwarf, estimate photometrically the spectral type of its close companion NLTT 51469B at $\sim$M6 and confirm the spectral type of the brown dwarf to be L9$\pm$1. Using radial velocity, proper motion and parallax we derived the $UVW$ space velocities of NLTT 51469A, showing that the system does not belong to any known young stellar moving group. The high $V, W$ velocities, lack of 670.8 nm Li I absorption line, and absence of H$α$ emission, detected X-rays or UV excess, indicate that the system is likely a member of the thin disk population and is older than 1 Gyr. For the parallactic distance of $46.6\pm1.6$ pc from Gaia DR2 we determined luminosities of $-1.50^{+0.02}_{-0.04}$ and $-4.4\pm0.1$ dex of the M3 and L9, respectively. Considering the spectrophotometric estimation which yields a slightly lower distance of $34^{+10}_{-13}$ pc the obtained luminosities are $-1.78^{+0.02}_{-0.04}$ and $-4.7^{+0.3}_{-0.5}$ dex. We also estimated their effective temperatures and masses, and obtained 3410$^{+140}_{-210}$ K and $0.42\pm0.02 M_{\odot}$ for the primary, and 1400-1650 K and $0.05-0.07 M_{\odot}$ for the wide companion. For the $\sim$M6 component we estimated $T_{eff}=2850\pm200 K$ and $m=0.10^{+0.06}_{-0.01} M_{\odot}$.

description: For centuries man has used coastal waters and the seas as a receptacle for %:/astes. Although the oceans have an enormous capacity to assimilate wastes, this limit is now being exceeded, or at least threatened, in many parts of the world. The resulting damages affect not only ecological stability and survivability of aquatic life, but also human uses and enjoyment of marine water. This paper identifies beneficial water uses impaired by marine pollution and evaluates them in an economic framework. Economic damages from current levels of pollution are estimated along •shorelines of the United States. Ranges of damage values are assumed to reflect uncertainty and incompleteness of the data base. Water uses that are assessed include commercial fishing, recreation (boating, sports fishing, swinming, and beach picnicking), and navigation. ' .At the international level, the severity of marine pollution is evaluated in a qualitative sense. Documented damages to recreational beaches and commercial fisheries are cited; and specific marine pollution problems are recognized for various countries. To date, economic analyses of international pollution control strategies have received minimal. attention, although legal policies on cooperation are evolving.
