description: Constraints from surveys of post common envelope binaries (PCEBs) consisting of a white dwarf plus an M-dwarf companion have led to significant progress in our understanding of the formation of close white dwarf binary stars with low-mass companions. The white dwarf binary pathways project aims at extending these previous surveys to larger secondary masses, i.e. secondary stars of spectral type AFGK. Here we present the discovery and observational characterization of three PCEBs with G-type secondary stars and orbital periods between 1.2 and 2.5 days. Using our own tools as well as MESA we estimate the evolutionary history of the binary stars and predict their future. We find a large range of possible evolutionary histories for all three systems and identify no indications for differences in common envelope evolution compared to PCEBs with lower mass secondary stars. Despite their similarities in orbital period and secondary spectral type, we estimate that the future of the three systems are very different: TYC 4962-1205-1 is a progenitor of a cataclysmic variable system with an evolved donor star, TYC 4700-815-1 will run into dynamically unstable mass transfer that will cause the two stars to merge, and TYC 1380-957-1 may appear as super soft source before becoming a rather typical cataclysmic variable star.

description: We present a model for tracking future task frequency distributions of individual adult worker honey bee (Apis mellifera L.) cohorts in a colony based on the composition of immatures at a specific time period. The user inputs the proportions of brood comb occupied by eggs, larvae, capped brood, or non-brood/empty cells. The model captured an experimental example where a brood comb is inserted into a surrogate colony and the individuals then emerge and express their adult lives. This model has clear application to many other experiments such as sublethal pesticide exposure. The model output is the expected proportion of cohort members engaged in a focal task at any given day post-insertion.
Processor architectures for synthetic aperture radar
Creators: name: Meisl, Peter G.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines processor architectures for Synthetic Aperture Radar (SAR). SAR is a remote sensing technique that requires large amounts of computation and memory to form images. Processor architectures are sought that exhibit high performance, are scalable, are flexible, and are cost effective to develop and build. Performance is taken to be the primary figure of merit. The three facets of systems design, namely algorithm, technology, and architecture, are each examined in the process of finding the best architecture implementations. The examination of the algorithms is begun by reviewing SAR processing theory with the intent of summarizing the background for typical SAR processor performance requirements. A representative set of SAR algorithms is analyzed to determine and compare their computational requirements and to characterize them in terms of basic digital signal processing (DSP) operation types. The algorithm partitioning options for parallel processing are classified and compared. The area of technology is addressed by surveying computing technologies that are relevant to SAR processing. The technologies considered cover computational devices, memory devices and interconnections. The knowledge of SAR algorithms and computing technology are then combined to study design considerations for the memory and interconnection subsystems of SAR processors. The requirement for two dimensional access to large data arrays is found to be the main complicating factor in memory design. The judicious use of wide data path widths, caches, interleaving and fast memory is discussed as a solution to the memory latency problem. The applicability of the most commonly used interconnection networks is examined. Buses, meshes, and crossbars are all found to be effective in certain situations. A classification of architectural approaches adapted to describe current and future SAR processors is used as the framework for the architecture selection. Feasible implementations of the architectural approaches are identified and their suitability for SAR is analyzed. Three approaches are identified as the most promising: networks of workstations, DSP chips, and field programmable gate arrays (FPGAs). A detailed examination is made of these three approaches. Four variations of the DSP approach are considered: general purpose DSPs, vector DSPs, a proposed optimised DSP, and digital filter devices. Each approach offers a different trade-off between performance and flexibility. The most cost effective architectures approaches are found to be those based on general purpose or vector DSPs. An original heterogeneous design is presented that combines the strengths of these two approaches.
Forward Neutral Pion Production in p+p and d+Au Collisions at sqrt(s_NN)=200 GeV

description: Measurements of the production of forward pi0 mesons from p+p and d+Au collisions at sqrt(s_NN)=200 GeV are reported. The p+p yield generally agrees with next-to-leading order perturbative QCD calculations. The d+Au yield per binary collision is suppressed as eta increases, decreasing to ~30% of the p+p yield at =4.00, well below shadowing expectations. Exploratory measurements of azimuthal correlations of the forward pi0 with charged hadrons at eta~0 show a recoil peak in p+p that is suppressed in d+Au at low pion energy. These observations are qualitatively consistent with a saturation picture of the low-x gluon structure of heavy nuclei.

description: Chitin is basically responsible for protecting the body of honey bees against external attacks due to its hard cellulose structure. The chitin-structured body of honey bees is destroyed by Varroa destructor, the world’s most devastating pest of Western honey bees; causes honey bee decline. Varroa harms honey bees not only by feeding but also by the wounds it inflicts. Varroa bites cause a hole in the centre of the wound, which is a source of bacterial infection. In this study, the aim was to investigate the potential application of a chitosan-based gel to recover the chitin layer. The experiment was set up in eight cages. Varroa bites were artificially created on experimental bees called as model honey bees in cages. Different solutions of a chitosan-based gel at different doses were applied to the cages. Results revealed that Varroa bite wounds do not heal until day 9 in control cages. Healing of wounds by chitosan-based gel application on 1–3 and 3–6 days showed dose dependence. In addition, the gel prevented hair loss in honey bees, which was observed as a side effect of Varroa infestation. In addition, chitosan dissolved in organic acids is a key advantage for the treatment of V. destructor in parallel with wound healing.

description: I review the literature's census of the cold gas in clusters of galaxies. Cold gas here is defined as the gas that is cooler than X-ray emitting temperatures (~10^7 K) and is not in stars. I present new Spitzer IRAC and MIPS observations of Abell 2597 (PI: Sparks) that reveal significant amounts of warm dust and star formation at the level of 5 solar masses per year. This rate is inconsistent with the mass cooling rate of 20 +/- 5 solar masses per year inferred from a FUSE [OVI] detection.

description: Terahertz time-domain spectroscopy is employed to investigate temperature-dependent properties of bulk chalcopyrite crystals (CdGeP$_2$, ZnGeP$_2$ and CdSiP$_2$). The complex spectra provide the refraction and absorption as a function of temperature, from which electron-phonon coupling and average phonon energies are extracted and linked to the mechanics of the A- and B-site cations. Also, AC conductivity spectra provide carrier densities and electron scattering times, the temperature dependence of which is associated with unintentional shallow dopants. Temperature dependence of the scattering time is converted into carrier mobility and modeled with microscopic transport mechanisms such as polar optical phonon, acoustic phonons, deformation potential, ionized impurity and dislocation scattering. Hence, analysis links the THz optical and electronic properties to relate microscopic carrier transport and carrier-lattice interactions.

description: We explore the properties of magnetic excitations on the trellis lattice which is relevant for the so-called telephone-number compounds A$_{14}$Cu$_{24}$O$_{41}$ and the system SrCu$_2$O$_3$. The trellis lattice consists of two-leg ladders which are coupled in a strongly frustrated fashion. We use the effective model obtained for a single two-leg spin ladder to calculate the two-dimensional one-triplon dispersion and the corresponding one-triplon contribution to the dynamical structure factor. Special attention is laid on signatures of the frustrating inter-ladder magnetic exchange. A detailed suggestion is made for an experimental detection of this exchange in inelastic neutron scattering experiments.

description: James Jurin wrote an extended essay on distinct and indistinct vision in 1738. In it he distinguished between ‘perfect’, ‘distinct’ and ‘indistinct vision’ as perceptual categories and his meticulous descriptions and analyses of perceptual phenomena contained observations which are akin to crowding. Remaining with the concepts of his day, however, he failed to recognize crowding as separate from spatial resolution. We present quotations from Jurin’s essay and place them in the context of the contemporary concerns with visual resolution and crowding.

Light-emitting heterostructures showing amplified spontaneous emission are used as illumination sources for speckle-free, full-field imaging, and transient optical labels are realized that incorporate QR codes with stably encoded information. The transient behavior is also studied at the microscopic scale, highlighting the real time evolution of material domains in the sublimating compound. Finally, the exhausted components are fully soluble in water thus being naturally degradable.

Hyperon Polarization in a Quark-Quark Scattering Model

Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A continuing mystery in particle physics is the large polarization observed in inclusive hyperon production in high energy p-p collisions. In this paper the authors advance the concept that the polarization effects can be accounted for in a simple model based on quarks becoming polarized in the direct q-q scattering process and where, at a fundamental level, the s quark is treated no differently than the u and d, except that it is required to have been created as part of a s-sbar pair prior to the collision. The q-q polarization parameters are extracted from p-p elastic scattering using a previous model and these are used to predict the Lambda polarization from the p-p data. Remarkably good agreement is obtained, raising the possibility that the large hyperon polarizations are no more of a mystery than the p-p polarization itself and that, at least at small pt, the two may be simply related. This concept is extended in an attempt to explain the polarizations observed in other inclusive hyperon processes with the finding that hyperon and elastic polarizations, which previously seemed almost unrelated, may have a simple and common origin.

description: Family Eylaidae Leach, 1815   The only known genus of the family, Eylais, is distributed worldwide, but the documentation of its diversity is at a preliminary stage. In the northern hemisphere, until the mid-20 th century, high numbers of species were described on the base of small differences in the shape of the frontal eye sclerite. Recently, many were synonymized when the high intraspecific variability of many character states was detected. Studies of B.P. Smith (1986) demonstrated the existence of species easily distinguishable at the larval stage, but not displaying remarkable differences as adults. Therefore, future taxonomic work should concentrate on all developmental stages, and at best include also molecular analyses.
 As far as data are available, Eylais larvae are parasites of adult water beetles belonging to at least 6 different families (e.g., Zawal 2004). The fact that many of these host insects are highly active and have extensive flight ranges, probably explains why many Eylais species have an extended distribution area and are able to colonize isolated habitats in arid areas or remote oceanic islands. The eylaid fauna of Madagascar is still strongly underdocumented. In addition to two species with a wide distribution over several continents, for two further, possibly endemic, but uncertain species, we are provided with single records only. The new records given here are based on the very old, probably outdated systematics of Koenike (1898).

description: We investigate the local time $(T_{loc})$ statistics for a run and tumble particle in an one dimensional inhomogeneous medium. The inhomogeneity is introduced by considering the position dependent rate of the form $R(x) = γ\frac{|x|^α}{l^α}$ with $α\geq 0$. For $α=0$, we derive the probability distribution of $T_{loc}$ exactly which is expressed as a series of $δ$-functions in which the coefficients can be interpreted as the probability of multiple revisits of the particle to the origin starting from the origin. For general $α$, we show that the typical fluctuations of $T_{loc}$ scale with time as $T_{loc} \sim t^{\frac{1+α}{2+α}}$ for large $t$ and their probability distribution possesses a scaling behaviour described by a scaling function which we have computed analytically. In the second part, we study the statistics of $T_{loc}$ till the RTP makes a first passage to $x=M~(>0)$. In this case also, we show that the probability distribution can be expressed as a series sum of $δ$-functions for all values of $α~(\geq 0)$ with coefficients appearing from appropriate exit problems. All our analytical findings are supported with the numerical simulations.

Direct numerical simulation of homogeneous nucleation and growth in a phase-field model using cell dynamics method

Year: 2008
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Homogeneous nucleation and growth in a simplest two-dimensional phase field model is numerically studied using the cell dynamics method. Whole process from nucleation to growth is simulated and is shown to follow closely the Kolmogorov-Johnson-Mehl-Avrami (KJMA) scenario of phase transformation. Specifically the time evolution of the volume fraction of new stable phase is found to follow closely the KJMA formula. By fitting the KJMA formula directly to the simulation data, not only the Avrami exponent but the magnitude of nucleation rate and, in particular, of incubation time are quantitatively studied. The modified Avrami plot is also used to verify the derived KJMA parameters. It is found that the Avrami exponent is close to the ideal theoretical value m=3. The temperature dependence of nucleation rate follows the activation-type behavior expected from the classical nucleation theory. On the other hand, the temperature dependence of incubation time does not follow the exponential activation-type behavior. Rather the incubation time is inversely proportional to the temperature predicted from the theory of Shneidman and Weinberg [J. Non-Cryst. Solids {\bf 160}, 89 (1993)]. A need to restrict thermal noise in simulation to deduce correct Avrami exponent is also discussed.

description: Modern Superconducting QUantum Interference Devices (SQUIDs) are commonly fabricated from either Al or Nb electrodes, with an in-situ oxidation process to create a weak link between them. However, common problems of such planar nano- and micro-SQUIDs are hysteretic current-voltage curves, and a shallow flux modulation depth. Here, we demonstrate the formation of both Josephson junctions and SQUIDs using a dry transfer technique to stack and deterministically misalign flakes of NbSe$_{2}$; allowing one to overcome these issues. The Josephson dynamics of the resulting twisted NbSe$_{2}$-NbSe$_{2}$ junctions are found to be sensitive to the misalignment angle of the crystallographic axes. A single lithographic process was then implemented to shape the Josephson junction into a SQUID geometry with typical loop areas of $\simeq$ 25 $μm^{2}$ and weak links $\simeq$ 600 nm wide. These devices display large stable current and voltage modulation depths of up to $ΔI_{c} \simeq$ 75$\%$ and $ΔV \simeq$ 1.4 mV respectively.

description: Honeydew honey belongs to the main honey sorts produced in European countries. Phloem sap feeding insects of the order Hemiptera excrete honeydew and honey bees process it into honey. In the case of high osmolality in the phloem sap, hemipteran species counteract osmotic pressure by producing oligosaccharides such as melezitose. Melezitose is a poorly digestible food source for bees, which can lead to honeydew flow disease. Moreover, melezitose-rich honey crystallises quickly and leads to economic losses for beekeepers. To understand the effects of diverse environmental factors on melezitose production, we analysed melezitose proportions with high performance anion-exchange chromatography of 620 honeydew samples collected between 2016 and 2019 considering botanical, zoological, geographical, and meteorological factors. We conducted a two-part logit-model considering all possible variables that could affect melezitose production simultaneously. Higher air temperatures and lower relative humidity levels increased melezitose production. Scale insect species and aphid species on Abies alba produced significantly less honeydew containing melezitose than aphid species on Picea abies. Honeydew with melezitose content was collected more often in natural areas with limited water reservoir capacities. All results lead to the conclusion that in the case the host trees have less access to water and an increasing osmolality of the phloem sap, the melezitose production by hemipteran species is indirectly enhanced. Our results may serve as an indicator of melezitose production and contribute to warning systems for beekeepers that help prevent harmful nutrition for bees or crystallised honey by timely removal of bee colonies from regions at risk.

description: The advent of Web3 technologies, leveraging blockchain and smart contracts, promises a paradigm shifttoward decentralized and autonomous economic interactions. However, the lack of robust trust and repu-tation mechanisms among pseudonymous participants hinders its evolution into a fully functional economicsystem. This paper introduces the Dmany Nexus Protocol, a decentralized reputation system thatquantifies user trustworthiness through verified on-chain and off-chain actions, addressing critical issues ofinformation asymmetry, moral hazard, and adverse selection inherent in decentralized networks.Building upon the live data and insights from the Dmany Quest Engine, the Nexus Protocol inte-grates advanced principles from information economics, game theory, and mechanism design to develop aquantifiable reputation metric—the Social Capital Score ((SCS)). This metric aggregates multiple facetsof user behavior, employing sophisticated anti-collusion algorithms and zero-knowledge proofs for privacypreservation. Unlike existing solutions, the Nexus Protocol offers a standardized, interoperable, and tamper-resistant reputation system that enhances economic efficiency and fosters mass adoption by enabling secure,privacy-preserving interactions among pseudonymous actors.Empirical analyses demonstrate that the protocol effectively mitigates security risks such as Sybil attacksand reduces information asymmetry, leading to improved task quality and reduced fraudulent activities indecentralized platforms. By establishing a foundation for trust and cooperation in the Web3 ecosystem,the Dmany Nexus Protocol significantly advances the potential for scalable and efficient decentralizedeconomies.

description: Honey bees are exposed to various pesticides via both acute and chronic routes. Transcriptional profiling based on quantitative real-time PCR could be used as a representative method to assess the effects of pesticides on honey bee physiology. In this method, the identification of reference genes left unaffected by pesticide treatment is required for accurate analysis; however, there have been no reports regarding such reference genes. In this study, the expression level fluctuations of two putative reference genes (arf1 and rab1), along with three commonly used reference genes (rpS18, actin, and gapdh), were investigated in different stages and tissues following treatment with fluvalinate, coumaphos, imidacloprid, and flupyradifurone, and their performances were compared using geNorm, BestKeeper, NormFinder and RefFinder. The expression stability of rab1a was the highest, followed by that of arf1, rpS18, actin, and gapdh, suggesting that rab1 and arf1 can be employed as reliable reference genes in pesticide studies.

description: We consider the problem of a self-interacting scalar field nonminimally coupled to the three-dimensional BTZ metric such that its energy-momentum tensor evaluated on the BTZ metric vanishes. We prove that this system is equivalent to a self-dual system composed by a set of two first-order equations. The self-dual point is achieved by fixing one of the coupling constant of the potential in terms of the nonminimal coupling parameter. At the self-dual point and up to some boundary terms, the matter action evaluated on the BTZ metric is bounded below and above. These two bounds are saturated simultaneously yielding to a vanishing action for configurations satisfying the set of self-dual first-order equations.

description: The North-Ecliptic Pole is an important region for extragalactic surveys. Deep/wide contiguous surveys are being performed by several space observatories. We analyse all ROSAT pointed and survey observations within 40 deg2 around the NEP, restricting the field-of-view to the inner 30' radius. We obtain an X-ray catalogue of 805 sources with 0.5-2 keV fluxes >2.9E-15 cgs, a factor of three deeper than the ROSAT All-Sky Survey in this field. The sensitivity and angular resolution of our data are comparable to the eROSITA All-Sky Survey expectations. We use HEROES optical and near-infrared imaging photometry from Subaru and CFHT telescopes together with literature catalogues and a new deep and wide Spitzer survey in the field to identify X-ray sources and calculate photometric redshifts for the candidate counterparts. In particular we utilize mid-IR colours to identify AGN X-ray counterparts. Despite relatively large error circles and faint counterparts, confusion and systematic errors, we obtain a rather reliable catalogue of 766 optical counterparts, redshifts and optical classifications. We find a new population of luminous absorbed X-ray AGN at large redshifts, not recognized in previous X-ray surveys, but identified in our work due to the unique combination of survey solid angle, X-ray sensitivity and multiwavelength photometry. We also use the WISE and Spitzer photometry to identify a sample of 185 AGN selected purely through mid-IR colours, most of which are not detected by ROSAT. Their redshifts and upper limits to X-ray luminosity and X-ray to optical flux ratios are even higher than for the new class of X-ray selected luminous AGN2. This unique dataset is important as reference for future deep surveys in the NEP region. Most of the absorbed distant AGN should be readily picked up by eROSITA, but they require sensitive mid-IR imaging to be recognized as optical counterparts.

description: In this paper we consider the hyperbolic-elliptic system of two conservation laws that describes the dynamics of an elastic material governed by a non-monotone strain-stress function. Following Abeyaratne and Knowles, we propose a notion of admissible weak solution for this system in the class of functions with bounded variation. The formulation includes an entropy inequality, a kinetic relation (imposed along any subsonic phase boundary), and an nucleation criterion (for the appearance of new phase boundaries). We prove the L1 continuous dependence of the solution to the Riemann problem. Our main result yields the existence and the stability of propagating phase boundaries. The proof is based on Glimm's scheme and in particular on techniques going back to Glimm-Lax. In order to deal with the kinetic relation, we prove a result of pointwise convergence for the phase boundary.

description: We investigate the gravitational effect of large-scale radiation perturbations on small-scale structure formation. In addition to making the growth of matter perturbations scale dependent, the free-streaming of radiation also affects the coupling between structure formation at small and large scales. We study this using Separate Universe N-body simulations to compute the (isotropized) squeezed-limit matter bispectrum and the linear halo bias. Our results show that the scale dependence in the growth of long-wavelength matter perturbations, caused by radiation, translates into these quantities acquiring a non-trivial scale-dependence at $k\lesssim 0.05$ Mpc$^{-1}$. In a universe with radiation composed of cosmic microwave background photons and three species of massless neutrinos, the bias of halos with $b = 2$ at high $k$ will decrease by $0.29\%,\ 0.45\%$ and $0.8\%$ between $k = 0.05$ Mpc$^{-1}$ and $k = 0.0005$ Mpc$^{-1}$ at redshifts $z=0,\ 1$, and $3$ respectively. For objects with $b\gg1$, these differences approach $0.43\%,\ 0.68\%$ and $1.2\%$ respectively.

description: Family Hydrodromidae K. Viets, 1936   This is a monotypic, morphologically very distinct family with uncertain relationships to other hydryphantoids. All investigated species of the genus Hydrodroma are, at the larval stage, parasitic on dipterans of the families Chironomidae and Chaoboridae (Meyer 1985, Smukalla & Meyer 1988). In deutonymphs and adults, a strong morphological homogeneity is observed with regard to numerous character states, and the type species H. despiciens (Müller, 1776) was for a long time considered the rare example of a water mite with a cosmopolitan distribution, being also reported from Madagascar. However, stable, species-specific patterns are found in leg setation as well as other character states such as integument structure, size and arrangement of lateral eye lenses, size of leg claws and proportions of leg segments (Gerecke 2017 and bibliography cited there). In the material available for this study, seven species were identified. They all have in common a similar size (body length in general between 700 and 1500 µm) and a remarkable intraspecific variability in proportions of palp segments. As, in certain limits, structure and arrangement of integument papillae may differ between various body parts, integument structure is described here for the posterior dorsum. Swimming setation is rather homogenous in the anterior pair of legs (absent from I-L, on II-L 0-2 on segment 5), but shows species-specific patterns on III-/IV-L.

A flexible system for the launch and reconstruction of localized acoustic waves

Publisher: name: University of British Columbia

description: A synthetic array system for launching and reconstructing localized acoustic waves has been developed. This low cost system is easily changed to many different configurations and for many different experiments. The major components of this system consist of an ultrasonic transducer transmitter-receiver pair, a high bandwidth amplifier, a single axis motion stage and PC-based data generation, acquisition and control cards. In addition to the design and assembly of this system, the equipment was further characterized so that the performance characteristics can be accounted for in future experiments. The signal amplitude decay with increasing transmitter-receiver distance behaves approximately as predicted by theory. The amplitude remains relatively constant up to the near field boundary. In the far field, the signal amplitude decays at a rate inversely proportional to the transducer separation. Transducer response as a function of the angle between the transmitter and receiver studied. Experimental measurements showed that transmitted fields are highly directional, similar to that predicted by theory. A method was devised to reconstruct received signals. Signals are first processed to remove unwanted low frequency noise. The signal is then integrated twice to recover the original signal, as predicted by theory. As a final confirmation of the operation of this system, a sample FWM pulse was generated using a 21 x 21 array of sources at a distance of 12 cm from the source array. The reconstructed result is compared with the theoretically reconstructed result as well as the ideal FWM pulse. The experimental results show characteristics similar to that which is predicted by theory. All required equipment and procedures have been devised to launch localized acoustic waves with this system. The experimental setup is ready to begin further experiments in localized acoustic waves.

description: We investigate the difference in the spread of COVID-19 between the states won by Donald Trump (Red) and the states won by Hillary Clinton (Blue) in the 2016 presidential election, by mining transportation patterns of US residents from March 2020 to July 2020. To ensure a fair comparison, we first use a K-means clustering method to group the 50 states into five clusters according to their population, area and population density. We then characterize daily transportation patterns of the residents of different states using the mean percentage of residents traveling and the number of trips per person. For each state, we study the correlations between travel patterns and infection rate for a 2-month period before and after the official states reopening dates. We observe that during the lock-down, Red and Blue states both displayed strong positive correlations between their travel patterns and infection rates. However, after states reopened we find that Red states had higher travel-infection correlations than Blue states in all five state clusters. We find that the residents of both Red and Blue states displayed similar travel patterns during the period post the reopening of states, leading us to conclude that, on average, the residents in Red states might be mobilizing less safely than the residents in Blue states. Furthermore, we use temperature data to attempt to explain the difference in the way residents travel and practice safety measures.

description: Atomic scale defects in semiconductors enable their technological applications and realization of novel quantum states. Using scanning tunneling microscopy and spectroscopy complemented by ab-initio calculations we determine the nature of defects in the anisotropic van der Waals layered semiconductor ReS$_2$. We demonstrate the in-plane anisotropy of the lattice by directly visualizing chains of rhenium atoms forming diamond-shaped clusters. Using scanning tunneling spectroscopy we measure the semiconducting gap in the density of states. We reveal the presence of lattice defects and by comparison of their topographic and spectroscopic signatures with ab initio calculations we determine their origin as oxygen atoms absorbed at lattice point defect sites. These results provide an atomic-scale view into the semiconducting transition metal dichalcogenides, paving the way toward understanding and engineering their properties.
