text: "We study the Undecided-State Dynamics (USD), a fundamental consensus process
in which each vertex holds one of k decided opinions or the undecided state. We
consider both the gossip model and the population protocol model. Prior work established
tight bounds on the consensus time of this process only for the regime \r\nk\r\n=\r\nO\r\n(\r\nn\r\n/\r\n(\r\nlog\r\n\r\nn\r\n)\r\n2\r\n)\r\n
(for the population protocol model) and k = O((n/log n)1/3) (for the gossip model),
often under restrictive assumptions on the initial configuration.\r\nIn this paper,
we obtain the first consensus-time guarantees for USD that hold for arbitrary
2 ≤ k ≤ n and for arbitrary initial configurations in both the gossip model and
the population protocol model. In the gossip model, USD reaches consensus within
\r\nO\r\n~\r\n(\r\nmin\r\n{\r\nk\r\n,\r\nn\r\n}\r\n)\r\n synchronous rounds with
probability 1 - p⊥ - n-c, where p⊥ is the gossip-specific probability of collapsing
to the all-undecided state in the first round. In the population protocol model,
USD reaches consensus within \r\nO\r\n~\r\n(\r\nmin\r\n{\r\nk\r\nn\r\n,\r\nn\r\n3\r\n/\r\n2\r\n}\r\n)\r\n
asynchronous interactions with high probability. We also present lower bounds
that match the upper bounds up to polylogarithmic factors for a specific initial
configuration and show that our upper bounds are essentially optimal."

text: High-voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material
for high power density in lithium-ion batteries. However, it suffers from poor
cycle life associated with the rock-salt phase transformation. This study presents
a straightforward synthesis approach to enhance the electrochemical performance
of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and
AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete
delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4,
and, more importantly, effectively mitigates the formation of the rock-salt phase,
thereby enhancing structural stability, as confirmed by operando X-ray absorption
spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the
optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities
of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g−1 at 0.2C, 0.5C, 1.0C,
2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode
and a high-loading cathode exhibit excellent cycling performance. They retain
80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5–4.9
V with cathode loading of 11 mg∙cm−2. The findings of this study will significantly
advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and
thereby enhancing their potential for practical applications.

text: 'We introduce a multi-material non-manifold mesh-based surface tracking algorithm
that converts self-intersections into topological changes. Our algorithm generalizes
prior work on manifold surface tracking with topological changes: it preserves
surface features like mesh-based methods, and it robustly handles topological
changes like level set methods. Our method also offers improved efficiency and
robustness over the state of the art. We demonstrate the effectiveness of the
approach on a range of examples, including complex soap film simulations with
thousands of interacting bubbles, and boolean unions of non-manifold meshes consisting
of millions of triangles.'

algorithm structure, contributed ideas and code to Sections 6 & 8, the mesh data

ideas and code to Sections 7, 8.5, and 5, the sparse grid data structure, algorithm
robustness and benchmarks, optimized the performance, produced all results, most
figures, and the supplementary video, helped write the text, and provided conceptual
solutions throughout the project. Malina Strugaru helped implement the mesh data
structure and designed re-meshing operations for non-manifold triangle meshes. Arian
Etemadi developed early prototypes for ideas in Sections 8.1 and 8.3 and helped
write the paper. Huidong Yang developed early prototypes for isosurface extraction
and visualization. Chris Wojtan helped conceive the project, helped write the paper,

text: Physics simulation in computer graphics can bring triangle meshes into topologically
invalid states. The method in this thesis contributed to Heiss-Synak* and Kalinov*
et al. [2024] who devised a non-manifold hybrid surface tracker—a surface tracker
that repairs explicit non-manifold triangle meshes with the help of the implicit
domain. Specifically, this thesis provides an algorithm for filling the holes
that are left after removing problematic parts of the mesh.

text: The popularity of permissioned blockchain systems demands BFT SMR protocols
that are efficient under good network conditions (synchrony) and robust under
bad network conditions (asynchrony). The state-of-the-art partially synchronous
BFT SMR protocols provide optimal linear communication cost per decision under
synchrony and good leaders, but lose liveness under asynchrony. On the other hand,
the state-of-the-art asynchronous BFT SMR protocols are live even under asynchrony,
but always pay quadratic cost even under synchrony. In this paper, we propose
a BFT SMR protocol that achieves the best of both worlds -- optimal linear cost
per decision under good networks and leaders, optimal quadratic cost per decision
under bad networks, and remains always live.

text: "With the lithium-ion technology approaching its intrinsic limit with graphite-based
anodes, lithium metal is recently receiving renewed interest from the battery
community as potential high capacity anode for next-generation rechargeable batteries.
In this focus paper, we review the main advances in this field since the first
attempts in the\r\nmid-1970s. Strategies for enabling reversible cycling and avoiding
dendrite growth are thoroughly discussed, including specific applications in all-solid-state
(polymeric and inorganic), Lithium-sulphur and Li-O2 (air) batteries. A particular
attention is paid to review recent developments in regard of prototype manufacturing
and current state-ofthe-art of these battery technologies with respect to the
2030 targets of the EU Integrated Strategic Energy Technology Plan (SET-Plan)
Action 7."

text: "We construct solutions with prescribed scattering state to the cubic-quintic
NLS (mathematical formular)in three spatial dimensions in the class of solutions
with (mathematical formular). This models disturbances in an infinite expanse
of (quantum) fluid in its quiescent state— the limiting modulus c corresponds
to a local minimum in the energy density.\r\nOur arguments build on work of Gustafson,
Nakanishi, and Tsai on the (defocusing) Gross–Pitaevskii equation. The presence
of an energy-critical nonlinearity and changes in the geometry of the energy\r\nfunctional
add several new complexities. One new ingredient in our argument is a demonstration
that\r\nsolutions of such (perturbed) energy-critical equations exhibit continuous
dependence on the initial data\r\nwith respect to the weak topology on H1/x."
