The University of Texas at Dallas (UTD or UT Dallas) is a public research university with its main campus in Richardson, Texas. The institution was initially established as a private research arm of Texas Instruments in 1961 as the "Graduate Research Center of the Southwest (GRCS)" and later renamed to the "Southwest Center for Advanced Studies (SCAS)". In 1969, SCAS was bequeathed to the state of Texas and joined the public University of Texas System, officially creating The University of Texas at Dallas. Approximately one-third of the college is located within Dallas County and includes an on-campus DART train station on the Silver Line (currently under construction - completion in 2022). Some UTD buildings such as the Center for BrainHealth and Callier Center are located in downtown Dallas next to The University of Texas Southwestern Medical Center. The university has been characterized by rapid growth in research output and its competitive undergraduate admissions policies since its inception. Less than 47 years after its founding, the Carnegie Foundation had classified the university as a doctoral research university with "Highest Research Activity"—faster than any other school in Texas. The university is associated with four Nobel Prizes, and has members of the National Academy of Science and National Academy of Engineering on its faculty. Research projects include the areas of Space Science, Bioengineering, Cybersecurity, Nanotechnology, and Behavioral and Brain Sciences. The University of Texas at Dallas offers more than 140 academic programs across its eight schools and hosts more than 50 research centers and institutes. From July 2018 to June 2019, the university granted 4,225 bachelor's degrees, 3,430 master's degrees, and 238 PhDs for a total of 7,893 degrees.The school has a Division III athletics program in the American Southwest Conference and fields 14 intercollegiate teams including a co-ed varsity eSports program. The university recruits worldwide for its chess team and has a nationally recognized debate team.
Agent Skills are structured packages of procedural knowledge that augment large language model (LLM) agents at inference time. Despite rapid adoption, there is no standard way to measure whether they actually help. We present SkillsBench, a benchmark whose current inventory contains 87 tasks across 8 domains paired with curated Skills and deterministic verifiers. Our latest aggregate evaluation runs the 87-task benchmark under matched no-Skills and curated-Skills conditions for 18 model-harness configurations. Curated Skills raise the average pass rate from 33.9
We present an analysis of metallicities and chemical abundances at 3 < z < 12 in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity relations are already in place at z approximate to 12 and evolve slowly (similar to 0.2 dex increase for gas, similar to 0.4 dex increase for stars at a fixed stellar mass) down to z = 3 , governed largely by the efficiency with which galaxies retain their metals, rather than gas fraction. The canonical fundamental metallicity relation survives in stars but breaks down and inverts for gas in low-mass galaxies ( M (*)less than or similar to 10(9)M(circle dot)) due to regular dilution by low-metallicity gas inflow. We find broad agreement of gas-phase N/O, Fe/O, and C/O with high-redshift observations, including the presence of nitrogen-rich galaxies (NRGs; log(N / O ) > -0.6) without the need for exotic yields in our chemical network. Instead, bursty star formation naturally generates order-of-magnitude excursions in N/O on less than or similar to 100 Myr time-scales due to temporally differential galactic winds; after a starburst, stellar feedback expels gas, leaving a large population of asymptotic-giant-branch stars to dominate the enrichment of the relatively low-mass interstellar medium. NRGs lie below the main sequence and typically exhibit EW[H beta] less than or similar to 40 angstrom, in apparent tension with observed high-EW NRGs. This tension is reconciled if observed NRGs are in the initial stages of a subsequent starburst, illuminating previously enriched gas, which is supported by the finding of high SFR surface density nitrogen-rich giant molecular clouds.
In this digital age, the adoption of digital technology (DT) is changing traditional business processes. Against this backdrop, we try to answer the question of whether DT could effectively bridge any interfirm knowledge capability gaps. Though effective knowledge transfer is dependent on the sender's and the receiver's knowledge capabilities, literature attributes very limited attention to their combined effects. Using signalling metaphor as the guiding framework, we forward disseminative capacity and absorptive capacity as the key capabilities of the sender and receiver, respectively, and study their combined effects on relational performance within vertical interfirm relationships. Additionally, with the belief that comprehending how DT could interplay with these capabilities holds crucial importance, we test the conjecture that DT can bridge knowledge capability gaps pertaining to the sender or the receiver. We position our hypotheses using the relational view and test them using the response surface methodology. The analysis is conducted based on a multi-respondent dyadic survey dataset that is augmented with secondary data and longitudinal performance data. Our findings showcase that disseminative capacity and absorptive capacity are natural counterparts and that the channel effectiveness resulting from adopting DT could serve as an offsetting capability that can effectively bridge certain knowledge capability gaps.
The sound horizon scale rs is a key source of information for measurements of H0 from early-time data, and is therefore a common target of new physics proposed to solve the Hubble tension. We present a sub-2% measurement of the Hubble constant that is independent of this scale, using data from the first data release of the Dark Energy Spectroscopic Instrument (DESI DR1). Building on previous work, we remove dependency on the sound horizon size using a heuristic rescaling procedure at the power spectrum level. A key innovation is the inclusion of uncalibrated (agnostic to rs) post-reconstruction BAO measurements from DESI DR1, as well as using the CMB acoustic scale theta & lowast; as a high-redshift anchor. Uncalibrated type-Ia supernovae are often included as an independent source of ohm m information; here we demonstrate the robustness of our results by additionally considering two supernova-independent alternative datasets. We find somewhat higher values of H0 relative to our previous work: 69.2+1.3-1.4, 70.3+1.4-1.2, and 69.6+1.3-1.8 km s-1 Mpc-1 respectively when including measurements from i) Planck/ACT CMB lensing & times; unWISE galaxies, ii) the DES Year 3 6 & times;2pt analysis, and iii) Planck/ACT CMB lensing + the DES Year 5 supernova analysis. These remarkably consistent constraints achieve better than 2% precision; they are among the most stringent sound horizon-independent measurements from LSS to date, and provide a powerful avenue for probing the origin of the Hubble tension.
Viologens (N-mono- and N,N '-disubstituted-4,4 '-bipyridiniums) are among the most extensively studied redox-active materials due to their reversible electrochemical reduction into deeply colored radical species, making them attractive for electrochromic applications. However, most research has focused on solution-based systems or amorphous polymer composites, which limits their integration into electronic devices. To expand their application range, we incorporated electrochemically active monosubstituted viologens into a crystalline solid-state framework as building blocks of a permanently porous metal-organic framework (MOF), {[Ni3F(cpb)(3)(bdc)(1.5)]& centerdot;guests}(n) (Hcpb & centerdot;Cl = 1-(4-carboxyphenyl)-4,4 '-bipyridinium chloride; H(2)bdc = benzene-1,4-dicarboxylic acid). We demonstrate that this MOF can be grown as thin films on conductive substrates via a simple solvent-mediated process. The MOF's high void space (>80%) enables efficient ionic mobility for reversible switching between transparent and colored states at a low driving voltage of 1.0 V. While electrochromic behavior in viologen-based MOFs has been rarely explored, this work represents one of the first examples of a permanently porous viologen MOF exhibiting robust and reversible electrochromism. The synergy between nanoporosity, which facilitates electrolyte penetration, and the redox-active ligand's low-voltage response positions this material as a promising candidate for smart windows and electrochromic display technologies
