description: Phagnalon viridifolium Decne. ex Boissier (1875: 220)
 Type:—[OMAN.] Regn. de Mascate, s.d., Aucher-Éloy 4774 (lectotype: G-BOIS, lost, designated by Qaiser & Lack 1985: 12; new lectotype: G barcode G00300769 [digital image!], designated here; isolectotypes: G barcode G00300642 [digital image!], K barcode K000910407!, LE barcodes LE00017954 and LE00017955!

(Image available at: http://www.ville-ge.ch/musinfo/bd/cjb/chg/adetail.php?id=225264).
 Notes:— Boissier (1875) described Ph. viridifolium from Oman: “Hab. in montibus regni Mascate Arabiae (Auch. 4774!)” and cited as type the specimen collected by Aucher-Eloy 4774. Unfortunately, the original material kept in G-BOIS herbarium was lost. Therefore, a new lectotype had to be designated. We found two specimens corresponding to the original gathering kept at the G general herbarium, and we selected as the lectotype the specimen G 00300769 because it is in a good state of preservation and morphologically agrees with the protologue. We found different isolectotypes in other institutions, nearly all of them having a printed label corresponding to the original gathering “Aucher-Eloy Herbier d’Orient Nº 4774”, and some with handwritten details of collection locality “Regn. Mascate ”. However, specimens corresponding to the original gathering are slightly different:for example, the specimen P 01816448 had a handwritten label bearing the same information about collection locality and collector “In regno Mascatensi Aucher Eloy n. 4774”. Similarly, the specimen P 01816460 bears two labels: the same printed label “Aucher-Eloy Herbier d’Orient Nº 4774” with the handwritten annotation “Djebel Akadar” as well as another handwritten label that reads “Arabie (Mascat)”.

description: This exploratory study examines the concept of the "tweet session" - instances where a user of the microblogging site Twitter posts two or more related tweets in a short period of time. The study outlines a set of characteristics that aid in the detection of topically cohesive units. Four of these properties are external to the tweet text: a 24-hour time frame, inclusion of at least two tweets, inclusion of originally authored tweets and the exclusion of replies. Four additional properties were derived from the natural language processing and information retrieval literature: lexical cohesion based on unigram and character bigram feature representations, conjunction use, signals of continuation, and anaphora resolution.
A sample of 220 user timelines was analyzed to detect series of tweets meeting the definition of a session as conceptualized in the study. 93.6% of timelines included at least one technical tweet session. Lexical cohesion as determined by cosine similarity retrieved the most sessions: 815 technical sessions when unigrams were used as the unit of tokenization, and 1391 technical sessions when character bigrams were used. The majority of users engaged in tweet sessions exceeding 140 characters (the Twitter-imposed limit for a single tweet); however, when unigrams were used in the feature representation approximately 47% of timelines had tweet sessions of less than 140 characters on average. This research shows that tweet sessions exist and can be detected by computational means.

description: Delays in amyotrophic lateral sclerosis (ALS) diagnosis can result in compromised disease management and unnecessary costs. We examined the extent of ALS misdiagnosis in the US and Europe. Data were collected via the Adelphi ALS Disease Specific Programme™, a cross-sectional survey of physicians and a medical chart review of their consulting patients with ALS in France, Germany, Italy, Spain, the UK (EU5), and the US. Between July 2020 and March 2021, eligible physicians (primary speciality neurology, active involvement in managing patients with ALS) abstracted data from patients (≥18 years old) with confirmed ALS. Overall, 138 physicians completed the survey (EU5 107, US 31), with data reviewed from 795 patient medical charts (EU5 568, US 227); 278 (35.0%) patients (EU5 183 [32.2%], US 95 [41.9%]) had received ≥1 initial misdiagnosis based on symptoms later attributed to ALS. Mean (SD) time from symptom onset to first healthcare professional consultation was 3.8 (5.2) months (EU5 4.3 [4.8] months, US 2.6 [5.8] months). Mean (SD) time from symptom onset to ALS diagnosis was 8.2 (12.5) months (EU5 9.6 [14.0] months, US 5.0 [6.8] months) and increased to 10.4 (17.9) for patients with a misdiagnosis (compared with 6.9 [7.2] for patients with no misdiagnosis). Physician-identified barriers to timely ALS diagnosis included the similarity of symptoms to other conditions and delayed referral to neurologists. Misdiagnosis of ALS is frequent, with a protracted diagnostic pathway. Targeted education of patients and physicians about signs and symptoms and benefits of prompt referral to multidisciplinary care are needed.

description: MXenes are a set of two-dimensional transition metal carbides and nitrides that offer many potential applications in energy storage and electronic devices. As an important parameter to design new electronic devices, we investigate the work functions of bare MXenes and their functionalized ones with F, OH, and O chemical groups using first-principles calculations. From our calculations, it turns out that the OH terminated MXenes attain ultralow work functions between 1.6 and 2.8 eV. Moreover, depending on the type of the transition metal, the F or O functionalization affects increasing or decreasing the work functions. We show that the changes in the work functions upon functionalizations are linearly correlated with the changes in the surface dipole moments. It is shown that the work functions of the F or O terminated MXenes are controlled by two factors: the induced dipole moments by the charge transfers between F/O and the substrate, and the changes in the total surface dipole moments caused by surface relaxation upon the functionalization. However, in the cases of the OH terminated MXenes, in addition to these two factors, the intrinsic dipole moments of the OH groups play an important role in determining the total dipole moments and consequently justify their ultralow work functions.

description: Some libraries are using video games to get young adults interested and active at their local public libraries. When exploring gamers and the use of video games in libraries, it is important to put the topic in context of what young adults want from the library and what types of programs, especially those focusing on video games, are successful in getting teens to patronize the library. This study examines the views of young adult library gamers on the idea of playing video games in the library and on public libraries in general. Participants of the Gaming Club at the Public Library of Charlotte and Mecklenburg County's Teen Loft were interviewed to look at their thoughts and perceptions of libraries and playing video games at the library.

description: Water quality in streams is determined by several factors, including geology, topography, climate, and anthropogenic changes. This study aimed to assess the effects of watershed physical, morphology, and precipitation seasonality on the water quality of two streams that supply drinking water to rural settlements and urban areas in the Cerrado-Amazonia transition region. We monitored 16 physico-chemical attributes of water at six different sample locations over three years (2013–2016). Our results indicate that eight of these physico-chemical attributes did not meet the standards for safe drinking water established by Brazilian legislation. Precipitation seasonality, degradation of riparian zones, stream length, and watershed slope were the most important predictors of impaired water quality. Our results highlight the importance of restoring and conserving riparian forests in order to maintain drinking water quality.

description: High stability and low settling rate of phosphate fines in water suspensions encountered the dry area-located mines with serious environmental and technical challenges. The best suggestion for these mines is paste thickener installation for dewatering. In this research, the novel procedure has been proposed for evaluating the potential of paste thickeners in dewatering mining tailings. The case study is Esfordi phosphate complex (Iran). Initially, the selection criteria of a proper flocculant (environmental effects, price, particle settling rate, turbidity of overflow water, and underflow water content) were evaluated for current consuming flocculant (A-27) and 12 other ionic and nonionic flocculants. Then, flocculation performance was ranked based on the type and concentration, applying multiple criteria decision-making (MCDM) techniques of ORESTE, MAPPAC, and ELECTRE. Subsequently, the pilot-scale tests were performed for the selected flocculants and the operational conditions were evaluated for the maximum underflow solid content of 70 wt.%. The results of the present research showed that installation and application of this type of thickener could be effective for the case study.

description: This annotated bibliography explores propaganda themes, phrases, and images in recruiting pamphlets and posters. The pamphlets are from 1918--1977 and explore a wide range of themes and the evolution of propaganda angles. All of the posters, with the exception of two, are from WWII and show similarities and differences in the recruiting methods of the branches of military service. Stereotypes are described as are portrayals of different branches which still apply today. The recruitment of women is explored, from the no-nonsense angle of WWII to the career-minded, civil-rights aware woman of the 1970's. The establishment of the Office of War Information is discussed, as are its poster production and distribution campaigns. Addresses the poster as the ideal medium in a pre-television age and pamphlets as another, supplemental, means of advertising.

description: We report on observations of the hydroxyl radical (OH) within The H{\sc I}, OH Recombination line survey (THOR) pilot region. The region is bounded approximately between Galactic coordinates l=29.2 to 31.5$^\circ$ and b=-1.0 to +1.0$^\circ$ and includes the high-mass star forming region W43. We identify 103 maser sites, including 72 with 1612\,MHz masers, 42 showing masers in either of the main line transitions at 1665 and 1667\,MHz and four showing 1720\,MHz masers. Most maser sites with either main-line or 1720\,MHz emission are associated with star formation, whereas most of the 1612\,MHz masers are associated with evolved stars. We find that nearly all of the main-line maser sites are co-spatial with an infrared source, detected by GLIMPSE. We also find diffuse OH emission, as well as OH in absorption towards selected unresolved or partially resolved sites. Extended OH absorption is found towards the well known star forming complex W43 Main.

description: Hordeum vulgare L. dust (HVW) chemically activated using Na2CO3 (HVW-Na2CO3) was characterised by several techniques (SEM, FTIR and TGA/DTG). The increase in the surface charge of the biomaterial induced by the activation process was demonstrated by multisweep cyclic voltammetry. The modified HVM was then exploited as carbon paste electrode (HVW-Na2CO3/CPE) modifier to prepare a sensor which was applied in the determination of Cd2+, Pb2+ and Hg2+at trace level by stripping voltammetry. Key experimental variables (nature of stripping medium, modifier mass in CPE, electrolysis time and potential and pH of preconcentration solution) were optimised to detect Cd2+, Pb2+ and Hg2+ at HVW-Na2CO3/CPE. Under optimised conditions, calibration plots were obtained for all analytes. The low limits of detection (3s/m) were found to be 1.82 nM, 0.0691 nM and 0.237 nM for Cd2+, Pb2+and Hg2+respectively. The sensor was successfully applied to the detection of trace metals in real samples.

(Image available at: http://specimens.kew.org/herbarium/ K 000910403).
 Notes:— Boissier (1875) described Ph. acuminatum and indicated the locality and collector as: “Hab. in Belutschiâ (Stocks!)”. Lack (1980: 44) selected as the lectotype the specimen collected by Stocks kept at G-BOIS herbarium. Unfortunately, all type specimens of Phagnalon species described by Boissier from G-BOIS were lost. Therefore, a new lectotype had to be designated. As there is no other isotype at G-BOIS, or indeed at G general herbarium, we selected the isotype kept at K as the new lectotype.

description: This paper investigates a selection of private libraries belonging to seventeenth-century artists living in Italy, Spain and the Netherlands. The contents of the inventories are recorded in inventories and artist biographies. This project elucidates the book-collecting practices of these artists, and how their libraries may have influenced their artistic production.    This paper is an analysis of literature in art history describing the book collections of specific artists. It relies upon the methodologies of collection practice, and the history of art bibliography. The seventeenth-century artists whose collections were surveyed were found to collect books with five primary goals in mind: elevation of social status, increase of intellectual status, increase of technical knowledge, compositional inspiration and assistance with subject matter and iconography. In general, book-collecting by artists was for professional reading, and there are few instances of books collected for recreational reading.

description: We present a spectral realization of the Riemann zeros based on the propagation of a massless Dirac fermion in a region of Rindler spacetime and under the action of delta function potentials localized on the square free integers. The corresponding Hamiltonian admits a self-adjoint extension that is tuned to the phase of the zeta function, on the critical line, in order to obtain the Riemann zeros as bound states. The model suggests a proof of the Riemann hypothesis in the limit where the potentials vanish. Finally, we propose an interferometer that may yield an experimental observation of the Riemann zeros.

description: We consider the spin-1/2 two-leg ladders with ferromagnetic (FM) interactions along legs and rungs. Using the stochastic series expansion QMC method, we study the low-temperature magnetic behavior of the system. An isolated spin-1/2 FM two-leg ladder is in the gapped saturated FM phase at zero temperature. As soon as the spin-1/2 FM two-leg ladders are connected with antiferromagnetic (AFM) inter-ladder interaction, a first-order commensurate-incommensurate quantum phase transition occurs in the ground state magnetic phase diagram. In fact a jump in the magnetization curve is observed. We found that, coupled spin-1/2 FM two-leg ladders are in a nonmagnetic phase at zero temperature. Applying a magnetic field, the ground state of coupled spin-1/2 FM two-leg ladders remains in the nonmagnetic phase up to a quantum saturate critical field.

description: The diffusion and the recycling of electric and electronic equipment waste (WEEE) are an important issue for industrialised countries. During treatment operations of this equipment, legacy and emerging halogenated flame retardant can be released in the environment, causing great concern for their toxicity. For this purpose, a method to simultaneously determine polybrominated biphenyl ethers, hexabromocyclododecane, 10 emerging brominated flame retardants and in parallel-polychlorinated biphenyls was optimised and applied to particulate matter samples collected within a WEEE facility. In this paper, starting from a previously published method, we drastically simplified the sample preparation, reducing the overall completion time, solvent consumption, costs and achieving adequate selectivity and sensitivity for all the target compounds. The multi–analyte method was evaluated in terms of reproducibility, linearity, recovery, limits of detection, limit of quantification, and matrix effect and compared to the previous method. Quantitative analyses were carried out by gas chromatography-mass spectrometry in negative chemical ionisation, using matrix-matched calibration curves. The reliability and robustness of the method were demonstrated through the analysis of certified and reference compounds in Standard Reference Material 2585. The most abundant compounds in particulate matter samples, collected in an electric and electronic equipment waste treatment plant, were BDE 47 (3.9 ng m−3), CB 138 (2.7 ng m−3), and 1,2-bis(2,4,6-tribromophenoxy) ethane (4.2 ng m−3).
Many-Body Localization : construction of the emergent local conserved operators via block real-space renormalization

Publisher: name: arXiv

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: A Fully Many-Body Localized (FMBL) quantum disordered system is characterized by the emergence of an extensive number of local conserved operators that prevents the relaxation towards thermal equilibrium. These local conserved operators can be seen as the building blocks of the whole set of eigenstates. In this paper, we propose to construct them explicitly via some block real-space renormalization. The principle is that each RG step diagonalizes the smallest remaining blocks and produces a conserved operator for each block. The final output for a chain of $N$ spins is a hierarchical organization of the $N$ conserved operators with $\left(\frac{\ln N}{\ln 2}\right)$ layers. The system-size nature of the conserved operators of the top layers is necessary to describe the possible long-ranged order of the excited eigenstates and the possible critical points between different FMBL phases. We discuss the similarities and the differences with the Strong Disorder RSRG-X method that generates the whole set of the $2^N$ eigenstates via a binary tree of $N$ layers. The approach is applied to the Long-Ranged Quantum Spin-Glass Ising model, where the constructed excited eigenstates are found to be exactly like ground states in another disorder realization, so that they can be either in the paramagnetic phase, in the spin-glass phase or critical.

description: Many data management applications must deal with data which is uncertain, incomplete, or noisy. However, on existing uncertain data representations, we cannot tractably perform the important query evaluation tasks of determining query possibility, certainty, or probability: these problems are hard on arbitrary uncertain input instances. We thus ask whether we could restrict the structure of uncertain data so as to guarantee the tractability of exact query evaluation. We present our tractability results for tree and tree-like uncertain data, and a vision for probabilistic rule reasoning. We also study uncertainty about order, proposing a suitable representation, and study uncertain data conditioned by additional observations.

Chodura and Debye sheaths for magnetic fields with grazing incidence -- kinetic simulations

description: When an unmagnetized plasma comes in contact with a material surface, the difference in mobility between the electrons and the ions creates a nonneutral layer known as the Debye sheath (DS). However, in magnetic fusion devices, the open magnetic field lines intersect the structural elements of the device with near grazing incidence angles. The magnetic field tends to align the particle flow along its own field lines, thus counteracting the mechanism that leads to the formation of the DS. Recent work using a fluid model [P. Stangeby, Nucl. Fusion {\bf 52}, 083012 (2012)] showed that the DS disappears when the incidence angle is smaller than a critical value (around $5^\circ$ for ITER-like parameters). Here, we study this transition by means of numerical simulations of a kinetic model both in the collisionless and weakly collisional regimes. We show that the main features observed in the fluid model are preserved: for grazing incidence, the space charge density near the wall is reduced, the ion flow is subsonic, and the electric field and plasma density profiles are spread out over several ion Larmor radii instead of a few Debye lengths as in the unmagnetized case. As there is no singularity at the DS entrance in the kinetic model, this phenomenon depends smoothly on the magnetic field incidence angle and no particular critical angle arises. The simulation results and the predictions of the fluid model are in good agreement, although some discrepancies subsist, mainly due to the assumptions of isothermal closure and diagonality of the pressure tensor in the fluid model.

Electrostatic engineering of strained ferroelectric perovskites from first-principles

description: Design of novel artificial materials based on ferroelectric perovskites relies on the basic principles of electrostatic coupling and in-plane lattice matching. These rules state that the out-of-plane component of the electric displacement field and the in-plane components of the strain are preserved across a layered superlattice, provided that certain growth conditions are respected. Intense research is currently directed at optimizing materials functionalities based on these guidelines, often with remarkable success. Such principles, however, are of limited practical use unless one disposes of reliable data on how a given material behaves under arbitrary electrical and mechanical boundary conditions. Here we demonstrate, by focusing on the prototypical ferroelectrics PbTiO3 and BiFeO3 as testcases, how such information can be calculated from first principles in a systematic and efficient way. In particular, we construct a series of two-dimensional maps that describe the behavior of either compound (e.g. concerning the ferroelectric polarization and antiferrodistortive instabilities) at any conceivable choice of the in-plane lattice parameter, a, and out-of-plane electric displacement, D. In addition to being of immediate practical applicability to superlattice design, our results bring new insight into the complex interplay of competing degrees of freedom in perovskite materials, and reveal some notable instances where the behavior of these materials depart from what naively is expected.

description: This study examined high school history students' decisions to read text on the computer screen or to print a copy. Subjects were randomly assigned either to an experimental website, which included additional features beyond the text, or to a control website, which only included the text. Results indicated that the decision to print or to read on the screen was often made before visiting a website and was not heavily impacted by the specific design. Overall, the control group had more positive responses to electronic text than did the experimental. On test questions, those who read the experimental version surpassed the performance of the control group and equaled the performance of those who read a printed copy.

description: Spectral line survey observations are conducted toward the high-mass protostar candidate NGC 2264 CMM3 in the 4 mm, 3 mm, and 0.8 mm bands with the Nobeyama 45 m telescope and the Atacama Submillimeter Telescope Experiment (ASTE) 10 m telescope. In total, 265 emission lines are detected in the 4 mm and 3 mm bands, and 74 emission lines in the 0.8 mm band. As a result, 36 molecular species and 30 isotopologues are identified. In addition to the fundamental molecular species, many emission lines of carbon-chain molecules such as HC5N, C4H, CCS, and C3S are detected in the 4 mm and 3 mm bands. Deuterated molecular species are also detected with relatively strong intensities. On the other hand, emission lines of complex organic molecules such as HCOOCH3, and CH3OCH3 are found to be weak. For the molecules for which multiple transitions are detected, rotation temperatures are derived to be 7-33 K except for CH3OH. Emission lines with high upper-state energies (Eu > 150 K) are detected for CH3OH, indicating existence of a hot core. In comparison with the chemical composition of the Orion KL, carbon-chain molecules and deuterated molecules are found to be abundant in NGC 2264 CMM3, while sulfur-bearing species and complex organic molecules are deficient. These characteristics indicate chemical youth of NGC 2264 CMM3 in spite of its location at the center of the cluster forming core, NGC 2264 C.

description: Mineral systems can be thought of as a combination of several critical elements, including the whole-lithosphere architecture, favorable geodynamic/tectonic events, and fertility. Because they are driven by processes across various scales, exploration benefits from a scale-integrated approach. There are open questions regarding the source of ore-forming fluids, the depth of genesis, and their transportation through the upper crust to discrete emplacement locations. In this study, we investigate an Au–Cu metal belt located at the margin of an Archean-Paleoproterozoic microcontinent. We explore the geophysical signatures by analyzing three-dimensional models of the electrical resistivity and shear-wave velocity throughout the lithosphere. Directly beneath the metal belt, narrow, vertical, finger-like low-resistivity features are imaged within the resistive upper-middle crust and are connected to a large low-resistivity zone in the lower crust. A broad low-resistivity zone is imaged in the lithospheric mantle, which is well aligned with a zone of low shear-wave velocity, examined with a correlation analysis. In the upper-middle crust, the resistivity signatures give evidence for ancient pathways of fluids, constrained by a structure along a tectonic boundary. In the lower lithosphere, the resistivity and velocity signatures are interpreted to represent a fossil fluid source region. We propose that these signatures were caused by a combination of factors related to refertilization and metasomatism of the lithospheric mantle by long-lived subduction at the craton margin, possibly including iron enrichment, F-rich phlogopite, and metallic sulfides. The whole-lithosphere architecture controls the genesis, evolution, and transport of ore-forming fluids and thus the development of the mineral system.
