Veteran–Novice Pairing for Tutors’ Professional Development

This mixed methods study examines whether veteran–novice mentorship between tutors, as part of continuous in-service professional development, would have a positive effect on either party’s transferable skills (e.g., communication, collaboration, and professionalism). Quantitative findings from pre- and postsurveys about the veteran–novice mentorship suggest that tutors have significant gains in some transferable skills, such as oral/written communication skills, teamwork/collaboration skills, digital technology skills, and career management skills, after attending the continuous in-service professional development. Quantitative findings from the pre- and postsurveys further indicate that novice tutors improve more, compared to veteran tutors, in their self-perceived oral/written communication skill levels. Qualitative findings from postmentorship interviews explain findings suggested by quantitative analysis, with contextual factors. This research study has bifold significance: “a theoretical perspective” on writing center work and research-supported professional development strategies. The findings of this study provide more food for thought on the subjects of how to design veteran–novice mentorships, how to target some transferable skills for professional development in the future, and how to exemplify the transferable skills in the survey to make those abstract constructs more concrete

PIE-NeRF: Physics-based Interactive Elastodynamics with NeRF

We show that physics-based simulations can be seamlessly integrated with NeRF to generate high-quality elastodynamics of real-world objects. Unlike existing methods, we discretize nonlinear hyperelasticity in a meshless way, obviating the necessity for intermediate auxiliary shape proxies like a tetrahedral mesh or voxel grid. A quadratic generalized moving least square (Q-GMLS) is employed to capture nonlinear dynamics and large deformation on the implicit model. Such meshless integration enables versatile simulations of complex and codimensional shapes. We adaptively place the least-square kernels according to the NeRF density field to significantly reduce the complexity of the nonlinear simulation. As a result, physically realistic animations can be conveniently synthesized using our method for a wide range of hyperelastic materials at an interactive rate.

Tetra­aqua­bis(2-methyl­benzimidazolium-1,3-diacetato-κO)zinc(II) tetra­hydrate

The asymmetric unit of the title compound, [Zn(C12H11N2O4)2(H2O)4]·4H2O, contains one-half of the complex mol­ecule and two uncoordin­ated water mol­ecules. The four water O atoms in the equatorial plane around the ZnII centre ( symmetry) form a distorted square-planar arrangement, while the distorted octa­hedral coordination geometry is completed by the O atoms of the zwitterionic 2-methyl­benzimidazolium-1,3-diacetate ligands in the axial positions. The benzimidazole ring system is planar, with a maximum deviation of 0.041 (3) Å. Intra­molecular O—H⋯O hydrogen bonding results in the formation of a non-planar six-membered ring. In the crystal structure, strong intra- and inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π contacts between benzimidazole rings [centroid–centroid distance = 3.899 (1) Å] may further stabilize the structure

{μ-trans-N,N′-Bis[(diphenyl­phosphan­yl)meth­yl]benzene-1,4-diamine-κ2 P:P′}bis­{(acetonitrile-κN)[dipyrido[3,2-a:2′,3′-c]phenazine-κ2 N 4,N 5]copper(I)} bis­(tetra­fluoridoborate)

In the centrosymmetric dinuclear title compound, [Cu2(C2H3N)2(C18H10N4)2(C32H30N2P2)](BF4)2, the CuI centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N′-bis­[(diphenyl­phosphan­yl)meth­yl]benzene-1,4-diamine (bpbda) ligand, and one N atom from an acetonitrile mol­ecule in a distorted tetra­hedral geometry. The bpbda ligand, lying on an inversion center, bridges two CuI centres into a Z-shaped complex. Intra­molecular π–π inter­actions between the dipyridophenazine ligand and the benzene ring of the bpbda ligand are observed [centroid–centroid distance = 3.459 (3) Å]. The crystal structure also involves inter­molecular π–π inter­actions between the dipyridophenazine ligands [centroid–centroid distance = 3.506 (3) Å], which lead to a one-dimensional supra­molecular structure

[μ-N,N,N′,N′-Tetra­kis(diphenyl­phosphino­meth­yl)benzene-1,4-diamine-κ4 P,P′:P′′,P′′′]bis­[bis­(nitrato-κO)palladium(II)]

The asymmetric unit of the title complex, [Pd2(NO3)4(C58H52N2P4)], contains one half-mol­ecule, in which the central benzene ring is located on a crystallographic centre of inversion. The Pd atom has a distorted square-planar coordination consisting of two P and two O atoms. In the crystal structure, inter­molecular C—H⋯O inter­actions link the mol­ecules into chains, and π–π contacts between the phenyl rings [centroid–centroid distance = 3.928 (3) Å] may further stabilize the structure

Superconductivity up to 30 K in the vicinity of quantum critical point in BaFe2_{2}(As1−x_{1-x}Px_{x})2_{2}

We report bulk superconductivity induced by an isovalent doping of phosphorus in BaFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$. The P-for-As substitution results in shrinkage of lattice, especially for the FeAs block layers. The resistivity anomaly associated with the spin-density-wave (SDW) transition in the undoped compound is gradually suppressed by the P doping. Superconductivity with the maximum $T_c$ of 30 K emerges at $x$=0.32, coinciding with a magnetic quantum critical point (QCP) which is evidenced by the disappearance of SDW order and the linear temperature-dependent resistivity in the normal state. The $T_c$ values were found to decrease with further P doping, and no superconductivity was observed down to 2 K for $x\geq$ 0.77. The appearance of superconductivity in the vicinity of QCP hints to the superconductivity mechanism in iron-based arsenides.Comment: 9 pages, 4 figures; more data; to appear in Journal of Physics: Condensed Matte

The title complex, [Ag2(C10H8N2)2(C32H30N2P2)](ClO4)2·2CH3COCH3, is a centrosymmetric dimer with pairs of AgI atoms bridged by N,N′-bis­(diphenyl­phosphinometh­yl)ben­zene-1,4-diamine ligands. In addition, each AgI atom is coordin­ated by one chelating 2,2′-bipyridine ligand, giving a distorted trigonal coordination environment
