DESCRIPTION (Fig. 17A, C)
 This taxon would be represented by at least seven teeth with a complete and sometimes denticulated lingual cingulum. The latter is quite different from that of the three teeth mentioned above (p. 509), in that it slopes regularly from front to back and ends in a low situated talonid. The trigonid is high with closely grouped cusps. The talonid (preserved on three specimens only) is shorter than that in Palaeoxonodon but still relatively elongated and with a short occlusal concavity; it is again labially recurved distally. There is no distal metacristid, only a very short crest at the base of the metaconid limiting labially the talonid surface. Where preserved, the paraconid is slightly inclined forwards and slightly smaller than the metaconid as a consequence of the distally inclined lingual cingulum. The antero-labial cusp (f) is well indicated and occupies the whole anterior base of the protoconid. Moreover, a slight labial cingulum may be present (the type is not preserved low enough). At most, one root is preserved so that the relative proportions of the two roots are uncertain; they were at least subequal if not equal.
The enamel of the holotype tooth not being intact, only the ovale f facet is certain. J.514 has a narrow wear facet on the anterior face of the protoconid which joins that of f and that on the tip of the paraconid, and a wider posterior facet which joins that of the paracone sulcus; the situation is nearly the same anteriorly on J.430. On J.289 the paraconal sulcus goes up to the tip of the metaconid.
This morphology partially resembles that of spalacotheriid symmetrodonts with the notable difference of a longer talonid with a concave occlusal component and the absence of a labial cingulid. Given the fact that the reduction of the talonid is the only apomorphic character of the lower molars recognized for symmetrodonts (Prothero 1981), the ordinal attribution of the new taxon must remain indeterminate.

description: We have computed one-loop bulk and brane mass renormalization effects in a five-dimensional gauge theory compactified on the M_4 \times S^1/Z_2 orbifold, where an arbitrary gauge group G is broken by the orbifold action to its subgroup H. The space-time components of the gauge boson zero modes along the H generators span the gauge theory on the orbifold fixed point branes while the zero modes of the higher-dimensional components of the gauge bosons along the G/H generators play the role of Higgs fields with respect to the gauge group H. No quadratic divergences in the mass renormalization of the gauge and Higgs fields are found either in the bulk or on the branes. All brane effects for the Higgs field masses vanish (only wave function renormalization effects survive) while bulk effects are finite and can trigger, depending on the fermionic content of the theory, spontaneous Hosotani breaking of the brane gauge group H. For the gauge fields we do find logarithmic divergences corresponding to mass renormalization of their heavy Kaluza-Klein modes. Two-loop brane effects for Higgs field masses are expected from wave function renormalization brane effects inserted into finite bulk mass corrections.

description: Much research has shown that applications have variable runtime cache requirements. In the context of the increasingly popular Spin-Transfer Torque RAM (STT-RAM) cache, the retention time, which defines how long the cache can retain a cache block in the absence of power, is one of the most important cache requirements that may vary for different applications. In this paper, we propose a Logically Adaptable Retention Time STT-RAM (LARS) cache that allows the retention time to be dynamically adapted to applications' runtime requirements. LARS cache comprises of multiple STT-RAM units with different retention times, with only one unit being used at a given time. LARS dynamically determines which STT-RAM unit to use during runtime, based on executing applications' needs. As an integral part of LARS, we also explore different algorithms to dynamically determine the best retention time based on different cache design tradeoffs. Our experiments show that by adapting the retention time to different applications' requirements, LARS cache can reduce the average cache energy by 25.31%, compared to prior work, with minimal overheads.

description: This article analyses a subcooled compression-absorption cascaded refrigeration system (SCRS) in comparison with a standalone compression-absorption cascaded refrigeration system (CRS) based on thermoeconomic optimization. Three different absorbent solution/solution mixture-refrigerant combinations have been tested as working pairs in vapor absorption refrigeration system (VARS), whereas four environmentally friendly refrigerants have been utilized in vapor compression refrigeration system (VCRS). The total annual cost of the system is formulated using energy, exergy, and economic performance of the system and is minimized for optimal operational parameters by implementing five recent evolutionary optimization techniques. The effect of compression subcooling on various operational parameters of the cascaded system is reported. Amid all absorbent solution/solution mixture-refrigerant-refrigerant combinations, R290 combined with (CaCl2-LiBr-LiNO3)-H2O provides the minimum total annual cost of 13,164.8 US$ yr−1 and 15,401.9 US$ yr−1 for CRS and SCRS, respectively. Sanitized Teaching Learning Based Optimization (sTLBO) and Coyote Optimization Algorithm (COA) obtain the optimal total annual cost for most VARS-VCRS absorbent solution/solution mixture-refrigerant-refrigerant combinations. Though the coefficient of performance (COP) of an optimal SCRS is about 250% higher than its optimal CRS, higher compressor work results in a higher penalty cost for the optimal SCRS, which is almost 190% higher than the optimal CRS. A quick convergence is observed for sTLBO and COA.
Constraining level densities using spectral data

description: Several models of level densities exist and they often make simplified assumptions regarding the overall behavior of the total level densities (LD) and the intrinsic spin and parity distributions of the excited states. Normally, such LD models are constrained only by the measured $D_0$, i.e. the density of levels at the neutron separation energy of the compound nucleus (target plus neutron), and the sometimes subjective extrapolation of discrete levels. In this work we use microscopic Hartree-Fock-Bogoliubov (HFB) level densities, which intrinsically provide more realistic spin and parity distributions, and associate variations predicted by the HFB model with the observed double-differential cross sections at low outgoing neutron energy, region that is dominated by the LD input. With this approach we are able to perform fits of the LD based on actual experimental data, constraining the model and ensuring its consistency. This approach can be particularly useful in extrapolating the LD to nuclei for which high-excited discrete levels and/or values of $D_0$ are unknown. It also predicts inelastic gamma (n,n$^{\prime}γ$) cross sections that in some cases can differ significantly from more standard LD models such as Gilbert-Cameron.

description: The N-galaxy 3C99, a Compact Steep-spectrum Source showing a triple asymmetric structure, has been observed with several arrays of radio telescopes at sub-arcsecond resolution. New images from MERLIN, European VLBI Network and the Very Long Baseline Array show that the source components detected in the central region of 3C99 have steep spectral indices, making it difficult to determine which of them is the core. The asymmetric radio structure of 3C99 is explained using the Scheuer-Baldwin continuous streaming model with a rather large difference in the interstellar medium density on the two sides of the central region. The age of 3C99 has been estimated; the source is found younger than 10^6 years.

description: Abstract: Integrated assessment models (IAMs) have emerged as key tools for building and assessing long term climate mitigation scenarios. Due to their central role in the recent IPCC assessments, and international climate policy analyses more generally, and the high uncertainties related to future projections, IAMs have been critically assessed by scholars from different fields receiving various critiques ranging from adequacy of their methods to how their results are used and communicated. Although IAMs are conceptually diverse and evolved in very different directions, they tend to be criticised under the umbrella of ‘IAMs’. Here we first briefly summarise the IAM landscape and how models differ from each other. We then proceed to discuss six prominent critiques emerging from the recent literature, reflect and respond to them in the light of IAM diversity and ongoing work and suggest ways forward. The six critiques relate to (a) representation of heterogeneous actors in the models, (b) modelling of technology diffusion and dynamics, (c) representation of capital markets, (d) energy-economy feedbacks, (e) policy scenarios, and (f) interpretation and use of model results.

description: We compute the elliptic flow generated by classical gluon fields in a high energy nuclear collision. The classical gluon fields are described by a typical momentum scale, the saturation scale Lambda_s, which is, for RHIC energies, of the order of 1-2 GeV. A significant elliptic flow is generated only over time scales on the order of the system size R. The flow is dominated by soft modes $p_{T} \sim Lambda_s / 4$ which linearize at very late times $tau \sim R \gg 1/Lambda_s$. We discuss the implications of our result for the theoretical interpretation of the RHIC data.

description: This research aims to study the pyrolysis characteristics and thermodynamic analysis of waste wind turbine blades (WTBs: composed of carbon fiber/unsaturated polyester resin) using a thermogravimetric analyzer (TG). The distribution of pyrolysis vapor products and their chemical compositions were analyzed. Also, pyrolysis experiments were carried out at various heating conditions to examine its effect on the vapor composition, and their pyrolysis kinetics was simulated using several modeling routes. In addition, all degradation regions of WTBs were mathematically simulated. The results showed that WTBs are rich in carbon element (53–88 wt.%) and volatile matter (26–30 wt.%), whereas TG measurements revealed that WTBs can fully degrade up to 500°C with a mass loss of 31%. Carbonyl (C=O) was the major functional group in the released vapor with a constant intensity even when the heating rate changed, while styrene was the major Gas chromatography-mass spectrometry compound with a significant abundance of 87% (at 30°C/min) versus 84% (at 5°C/min). Finally, kinetic investigations manifested that WTBs with a specific configuration have lower average activation energies (Ea) estimated at 172 kJ/mol (KAS), 220 kJ/mol (FWO), 194 kJ/mol (Friedman), and 159 kJ/mol (Vyazovkin and Cai), and FWO provides the highest R2 of 0.99. This decrease in Ea and the reaction complexity is caused by high conductivity of carbon fibers which helps in increasing the heat transfer and speeding up the reaction. The average enthalpy and Gibbs free energy were estimated in the ranges of 166–215 kJ/mol and 114–226 kJ/mol, respectively. Based on that, resin and carbon fibers can be recovered from WTBs using pyrolysis treatment.
Generalized Abraham Forces on Molecules: from classical to quantum

Subjects: subject: Optics (physics.optics)

description: Abraham forces are defined as electromagnetic forces on neutral objects caused by the presence of slow, time-dependent, homogeneous electromagnetic fields. Only a few experimental observations have been reported, and different formulations exist in literature. The ``standard" Abraham force is usually associated with the full derivative $\partial_t(\mathbf{E} \times \mathbf{B})$ of homogeneous electric and magnetic fields. We show that this full derivative is wrong in general, since the classical Maxwell theory contains subtle induced-dipole forces that contribute to the Abraham force, which thus breaks the dual symmetry between electric and magnetic components. We investigate other manifestations of Abraham forces and torques and estimate orders of magnitude, e.g related to chiral, moving or rotating matter. Some of them are also severely violating dual symmetry. We provide a quantum description of the Abraham force. Apart from being more elegant and less technical, this quantum treatment paves the way for future studies of Abraham forces on complex molecules involving spin and spin-orbit coupling, and also facilitates the inclusion of the quantum vacuum.

Abundance determinations in HII regions: model fitting versus Te-method

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: The discrepancy between the oxygen abundances in high-metallicity HII regions determined through the Te-method (and/or through the corresponding "strong lines - oxygen abundance" calibration) and that determined through the model fitting (and/or through the corresponding "strong lines - oxygen abundance" calibration) is discussed. It is suggested to use the interstellar oxygen abundance in the solar vicinity, derived with very high precision from the high-resolution observations of the weak interstellar absorption lines towards the stars, as a "Rosetta stone" to verify the validity of the oxygen abundances derived in HII regions with the Te-method at high abundances. The agreement between the value of the oxygen abundance at the solar galactocentric distance traced by the abundances derived in HII regions through the Te-method and that derived from the interstellar absorption lines towards the stars is strong evidence in favor of that i) the two-zone model for Te seems to be a realistic interpretation of the temperature structure within HII regions, and ii) the classic Te-method provides accurate oxygen abundances in HII regions. It has been concluded that the "strong lines - oxygen abundance" calibrations must be based on the HII regions with the oxygen abundances derived with the Te-method but not on the existing grids of the models for HII regions.

description: In this study, hybrid renewable power systems (HRPS) based on biomass-fired (BF) and concentrating solar power (CSP) technologies are investigated. Parabolic trough collector (PTC), linear Fresnel reflector (LFR) and solar tower (ST) as CSP technologies are considered. This study aims to determine and compare exergoeconomic and exergoenvironmental factors, as well as and the relative cost and environmental impact differences of three proposed HRPS options for the district of Faro in the province of Garoua, Cameroon. Also, advanced exergy destruction expressions are used. We found the optimized exergoeconomic and exergoenvironmental factors for the subsystems of HRPS to be between 0.04–0.98 and 0.05–0.98, respectively. They have the highest values for the drying system (DS), and the lowest values for the solar-biomass field (SF+BF). The relative cost and environmental impact differences for the subsystems of HRPS are in the ranges of 0.07–0.79 and 0.28–0.96, respectively. They have the highest values for the DS, and the lowest values for the power block (PB). According to the levelized exergoeconomic/exergoenvironmental performances, PTC – BF presents the worst results before the optimization. ST – BF shows the best exergoeconomic and exergoenvironmental performance in the optimization process. The results of the sensitivity and optimization analyses reveal that it is essential to conduct eco-indicator and advanced exergy analyses to avoid high environmental impact points and specific exergy destructions.

description: Air source assisted ground source composite heat pump (DSHP) system is a combination of ground source heat pump (GSHP) and air source heat pump (ASHP) that makes use of both underground and outdoor temperatures to ensure long-term stability and reliability. The development of a carbon emission model for DSHP system involved a life-cycle assessment (LCA). This model was used to analyze the energy savings of DSHP in two different areas of China Nanjing and Hohhot. In both cases, an office building with an area of 3040 m2 was used as the subject of the study. The evaluation of energy savings using TRNSYS dynamic simulations revealed that the operation stage accounts for about 75%-85% of the carbon emission in the entire life cycle assessment of DSHP systems, Among them, refrigerant leakage produces a carbon footprint of more than 20%. The installation stage accounts for about 10% of the emissions, while the adjustment of the power energy structure during operation is crucial in achieving energy savings and emission reductions. A comparison study shows that DSHP can lower emissions by up to 23% when compared to traditional air conditioning systems like gas boiler and chiller system (BLR-CH). The use of DSHP is therefore a highly effective alternative for organizations committed to reducing their carbon footprint.

description: We propose to control of an electron-hole superfluid in semiconductor coupled quantum wells and double layers of two-dimensional (2D) material by an external periodic field. This can either be created by the gates periodically located and attached to the quantum wells or double layers of 2D material or by the Moiré pattern of two twisted layers. The dependence of the electron-hole pairing order parameter on the temperature, the charge carrier density, and the gate parameters is obtained by minimization of the mean-field free energy. The second order phase transition between superfluid and electron-hole plasma, controlled by the external periodic gate field, is analyzed for different parameters.

description: In sustainable energy systems, the salt gradient solar pond has emerged as an eco-friendly approach to thermal energy storage. This study investigates the benefit of an East-West (EW) reflector and coal cinder additive (CC) to improve the exergy efficiency in the inner zones of a salt gradient solar trapezoidal pond. Additionally, it presents a temperature distribution model for solar ponds. In this study, we designed, constructed, and analyzed salt gradient trapezoidal solar ponds, evaluating them from an exergy perspective and comparing them to conventional trapezoidal systems. Our findings reveal that the implementation of a double glass cover led to a substantial increase in the average temperature of the heat storage zone, registering a 10.12% boost for the conventional trapezoidal system and a 12.31% enhancement for the trapezoidal system with East-West reflectors. Moreover, the average energy and exergy efficiencies of the lower convection zone for the conventional trapezoidal systems were determined to be 9.2% and 0.5%, respectively, while for the trapezoidal system with coal cinder additives and east-west reflectors, these values were notably higher, at 15.4%, and 0.94%, respectively.

The constraint is not imposed by hand, but appears naturally when we study a particular type of local gauge transformations. In this way, all standard techniques to treat gauge theories are available. We will show that this theory lives at one-loop. Also this model retains some quantum characteristic of the usual non-abelian gauge theories as asymptotic freedom.

description: The ELIXIR Plant Sciences Community is an interdisciplinary group of researchers with diverse backgrounds from computer science to different fields of plant biology. We answer the needs of both bioinformaticians and plant biologists.

The Community objective is to develop services supporting the integration and linking of phenotypic, genotypic, omics (e.g. expression, metabolomics, etc.), environmental, and bibliographic data. The underlying scientific use cases encompass fundamental and applied plant sciences, including genetics, system biology and omics approaches, within the broader context of climate change, agroecology, food security, and sustainable agriculture. 

To meet the current challenges in agriculture, the ELIXIR Community promotes tools, databases, standards, and best practices for plant research while developing joint initiatives such as international projects and events in collaboration with European infrastructures (EMPHASIS, AnaEE-ERIC, Euro-Bioimaging, METROFOOD-RI). The ELIXIR Community also supports the establishment of links to structuring national projects and initiatives such as NFDI in Germany, or the french Agroecology and ICT program. 

Despite ongoing efforts, challenges remain, such as the continued scattering of plant molecular and cellular data, which hampers efficient data integration and reuse. Additionally, progressing toward a comprehensive agriculture data space is essential to address the interdisciplinary challenges that modern agriculture faces. Strengthening engagement with related research communities, such as those working on plant pathogens, is also a priority to ensure a holistic approach to plant science and agricultural research.

Finally the Plant Sciences Community links with other ELIXIR Communities and Focus Groups, in particular to contribute to the objectives and priority of the Biodiversity, Food Security and Pathogens and of the Cellular and Molecular Research scientific priority areas.

description: We argue that the van Dam-Veltman-Zakharov discontinuity arising in the $M^2 \to 0$ limit of the massive graviton through an explicit Pauli-Fierz mass term could be absent in anti de Sitter space. This is possible if the graviton can acquire mass spontaneously from the higher curvature terms or/and the massless limit $M^2\to 0$ is attained faster than the cosmological constant $Λ\to 0$. We discuss the effects of higher-curvature couplings and of an explicit cosmological term ($Λ$) on stability of such continuity and of massive excitations.

description: The discharge of untreated textile dyeing wastewater containing azo dyes has significant ecological consequences. The incomplete biodegradation of these dyes can produce harmful and carcinogenic aromatic amines (AAs), which pose a threat to the environment. This study evaluates the treatment of real textile dyeing wastewater containing azo dyes by two different systems: an anoxic sequential batch reactor (A/O-SBR) and an aerobic sequential batch reactor (A-SBR). The effects of hydraulic retention time (HRT) on both systems were investigated in terms of chemical oxygen demand (COD), total nitrogen (TN), color, and AAs removal. Ranging between 85% and 92%, the COD removal efficiency was almost similar in the A/O-SBR and A-SBR systems, suggesting that the aerobic phase is primarily responsible for COD removal. However, A/O-SBR showed higher removal of color (90%) than A-SBR (75%) due to the presence of an anoxic phase. HRT has a significant impact on color removal in both systems. However, there was no significant effect on COD removal when HRT exceeded 12 h. According to LC-MS/MS analysis, increasing the HRT from 12 h to 24 h increased the AAs concentration in the anoxic phase, from 253 ng/L to 261 ng/L and slightly decreased the AAs concentration in the aerobic phase from 107 ng/L to 102 ng/L. This resulted in an overall improvement in both dye and AAs removal. The presence of aerobic phase in A/O-SBR and A-SBR demonstrates strong AAs removal capacity. GC-MS/MS analysis indicated that as the HRT of A/O-SBR and A-SBR increased, the number of by-products increased.

description: Urocyon Baird, 1858
 Type Species: Urocyon cinereoargenteus (Schreber), 1775.
 Included Fossil Species: U. progressus Stevens, 1965; U. minicephalus Martin, 1974; U. webbi, n. sp.; U. galushai, n. sp.; and U. citrinus, n. sp.
Distribution: Medial Hemphillian to Recent in North America and Recent in Central America and northern South America.
 Revised Diagnosis: Differs from other vulpines in the following apomorphies: nasals extend posterior to the frontal-maxillary suture; larger more posterieorly extended depression on dorsal surface of postorbital process accentuated by parasagittal ridges that begin at postorbital processes; frontal crests lyrate, strongly ridged, and joining behind frontoparietal suture; frontal part of braincase more expanded with wider postorbital constriction; medial cusplets on I1–I2 absent; canines with short and little recurved crowns; anterolabial cingulum of P4 often produced as parastyle; m1 entoconid and hypoconid usually connected by cristids to form transverse crest, hypoconulid relatively large; m2 trigonid shorter with paraconid varying from small (U. citrinus) to absent, talonid narrower with hypoconulid varying from distinct cusp to shelf; and in derived species, horizontal ramus with subangular lobe, condyle above alveolar border, and shallow depression ventral to masseteric fossa.
 Discussion: Urocyon is considered the sister taxon of Metalopex. Unlike other vulpines, they have a protostylid on m1 and m2 and a strong labial cingulum on m2 that may be linked with the base of the welldeveloped protostylid. These synapomorphies are evidence of their phyletic relationship.
 As listed in the diagnosis, the morphology of the lower molars of Urocyon are more complex, with the consistent presence of the m1 protostylid, the entoconid and hypoconid being generally joined by a transverse crest, and the hypoconulid being larger. The m2 trigonid in Urocyon is very short with the paraconid generally absent, although there is a paracristid. In the most derived species of Urocyon, there is a shallow depression beneath the masseteric fossa, and a prominent subangular lobe is present, which may be keeled ventrally, strongly angled posteriorly, and spinose.

On free energy of 2-d black hole in bosonic string theory

description: Trying to interpret recent matrix model results (hep-th/0101011) we discuss computation of classical free energy of exact dilatonic 2-d black hole from the effective action of string theory. The euclidean space-time action evaluated on the black hole background is divergent due to linear dilaton vacuum contribution, and its finite part depends on a subtraction procedure. The thermodynamic approach based on subtracting the vacuum contribution for fixed values of temperature and dilaton charge at the "wall" gives (as in the leading-order black hole case) S= M/T for the entropy and zero value for the free energy F. We suggest that in order to establish a correspondence with a non-vanishing matrix model result for F one may need an alternative reparametrization-invariant subtraction procedure using analogy with non-critical string theory (i.e. replacing the spatial coordinate by the dilaton field). The subtraction of the dilaton divergence then produces a finite value for the free energy. We also propose a microscopic estimate for the entropy and energy of the black hole based on the contribution of non-singlet states of the matrix model.

description: We investigate the chances that neutron stars act as the lense in a gravitational microlensing event towards the galactic bulge or a spiral arm. The observation of neutron stars by means of gravitational microlensing would allow the estimation of neutron star masses independently of the property of being a pulsar in a binary system. We estimate the contribution of neutron stars to the optical depth and the lensing rate based on two different models of the pulsar distribution in the galaxy. Since only a small fraction of all neutron stars are pulsars, it is unlikely to find a pulsar that acts as a microlense by chance. A position comparison of known radio pulsars with observed microlensing candidates towards the galactic bulge and spiral arms shows no candidate pair, which is consistent with the theoretical expectation. To improve the probability of microlensing a pulsar, we suggest to search for gravitational microlensing events of known nearby high proper motion pulsars. The pulsar PSR J1932+1059 is a good candidate for an astrometric detection of gravitational lensing.

description: The open cluster (OC) NGC 2453 is of particular importance since it has been considered to host the planetary nebula (PN) NGC 2452, however their distances and radial velocities are strongly contested. In order to obtain a complete picture of the fundamental parameters of the OC NGC 2453, 11 potential members were studied. The results allowed us to resolve the PN NGC 2452 membership debate. Radial velocities for the 11 stars in NGC 2453 and the PN were measured and matched with Gaia data release 2 (DR2) to estimate the cluster distance. In addition, we used deep multi-band UBVRI photometry to get fundamental parameters of the cluster via isochrone fitting on the most likely cluster members, reducing inaccuracies due to field stars.The distance of the OC NGC 2453 (4.7 $\pm$ 0.2 kpc) was obtained with an independent method solving the discrepancy reported in the literature. This result is in good agreement with an isochrone fitting of 40-50 Myr. On the other hand, the radial velocity of NGC 2453 ($78 \pm 3$ km s$^{-1}$) disagrees with the velocity of NGC2452 ($62 \pm 2$ km s$^{-1}$). Our results show that the PN is a foreground object in the line of sight. Due to the discrepancies found in the parameters studied, we conclude that the PN NGC 2452 is not a member of the OC NGC 2453.

description: When solving elliptic partial differential equations in a region containing immersed interfaces (possibly evolving in time), it is often desirable to approximate the problem using an independent background discretisation, not aligned with the interface itself. Optimal convergence rates are possible if the discretisation scheme is enriched by allowing the discrete solution to have jumps aligned with the surface, at the cost of a higher complexity in the implementation. A much simpler way to reformulate immersed interface problems consists in replacing the interface by a singular force field that produces the desired interface conditions, as done in immersed boundary methods. These methods are known to have inferior convergence properties, depending on the global regularity of the solution across the interface, when compared to enriched methods. In this work we prove that this detrimental effect on the convergence properties of the approximate solution is only a local phenomenon, restricted to a small neighbourhood of the interface. In particular we show that optimal approximations can be constructed in a natural and inexpensive way, simply by reformulating the problem in a distributionally consistent way, and by resorting to weighted norms when computing the global error of the approximation.

description: The development of new quantum chemical methods requires extensive benchmarking to establish the accuracy and limitations of a method. Current benchmarking practices in computational chemistry use test sets that are subject to human biases and as such can be fundamentally flawed. This work presents a thorough benchmark of diffusion Monte Carlo (DMC) for a range of systems and properties as well as a novel method for developing new, unbiased test sets using multivariate statistical techniques. Firstly, the hydrogen abstraction of methanol is used as a test system to develop a more efficient protocol that minimises the computational cost of DMC without compromising accuracy. This protocol is then applied to three test sets of reaction energies, including 43 radical stabilisation energies, 14 Diels-Alder reactions and 76 barrier heights of hydrogen and non-hydrogen transfer reactions. The average mean absolute error for all three databases is just 0.9 kcal/mol. The accuracy of the explicitly correlated trial wavefunction used in DMC is demonstrated using the ionisation potentials and electron affinities of first- and second-row atoms. A multi-determinant trial wavefunction reduces the errors for systems with strong multi-configuration character, as well as for predominantly single-reference systems. It is shown that the use of pseudopotentials in place of all-electron basis sets slightly increases the error for these systems. DMC is then tested with a set of eighteen challenging reactions. Incorporating more determinants in the trial wavefunction reduced the errors for most systems but results are highly dependent on the active space used in the CISD wavefunction. The accuracy of multi-determinant DMC for strongly multi-reference systems is tested for the isomerisation of diazene. In this case no method was capable of reducing the error of the strongly-correlated rotational transition state. Finally, an improved method for selecting test sets is presented using multivariate statistical techniques. Bias-free test sets are constructed by selecting archetypes and prototypes based on numerical representations of molecules. Descriptors based on the one-, two- and three-dimensional structures of a molecule are tested. These new test sets are then used to benchmark a number of methods.
