An Infinite Family of Real Quadratic Fields with Three Classes of Perfect Unary Forms
In this paper, we revisit the theory of perfect unary forms over real quadratic fields. Specifically, we deduce an infinite family of real quadratic fields $\mathbb{Q}(\sqrt{d})$ when $d=2$ or $3$ mod $4$, such that there are three classes of perfect unary forms up to homothety and equivalence. This work, along with the work in \cite{unitred}, seems to suggest that the number of classes of perfect unary forms is related to the fundamental unit of $K$.

Cutoff Scale of Quadratic Gravity from Quantum Focusing Conjecture
We derive the cutoff length scale of the quadratic gravity in $d \geq 5$ dimensional spacetime by demanding that the quantum focusing conjecture for the smeared quantum expansion holds at the classical level. The cutoff scale has different dependence on the spacetime dimension depending on the sign of the coupling constant of the quadratic gravity. We also investigate a concrete example of the 5-dimensional Schwarzschild spacetime and directly confirm that the quantum focusing conjecture holds …

Improving the accuracy and consistency of the energy quadratization method with an energy-optimized technique
We propose an energy-optimized invariant energy quadratization method to solve the gradient flow models in this paper, which requires only one linear energy-optimized step to correct the auxiliary variables on each time step. In addition to inheriting the benefits of the baseline and relaxed invariant energy quadratization method, our approach has several other advantages. Firstly, in the process of correcting auxiliary variables, we can directly solve linear programming problem by the energy-o…

Schoigu: Ukrainische Streitkräfte Richtung Westen zurückgedrängt
Nach Angaben des russischen Verteidigungsministers Sergej Schoigu drängt die russische Armee die "ukrainischen Verbände nach Westen zurück". Laut russischen Medien sagte Schoigu bei einem Treffen von Kommandeuren, die russischen Streitkräfte hätten seit Neujahr 403 Quadratkilometer Territorium erobert und im März die Kontrolle über fünf Städte und Dörfer in der …

Modular Multi-Rotors: From Quadrotors to Fully-Actuated Aerial Vehicles
Traditional aerial vehicles have specific characteristics to perform specific tasks but designing a versatile vehicle that can adapt depending on the task is still a challenge. Based on modularity, we propose an aerial robotic system that can increase its payload capacity and actuated degrees of freedom by reconfiguring heterogeneous modules to adapt to different task specifications. The system consists of cuboid modules propelled by quadrotors with tilted rotors. We present two module designs …

Jolteon and Ditto: Network-Adaptive Efficient Consensus with Asynchronous Fallback
Existing committee-based Byzantine state machine replication (SMR) protocols, typically deployed in production blockchains, face a clear trade-off: (1) they either achieve linear communication cost in the happy path, but sacrifice liveness during periods of asynchrony, or (2) they are robust (progress with probability one) but pay quadratic communication cost. We believe this trade-off is unwarranted since existing linear protocols still have asymptotic quadratic cost in the worst case. We desi…

Drei schöne Dinge heute.
- warme Sonne genossen
- 5 km an der Donau spaziert
- gutes Eis gehabt
- Bärlauch gepflückt und eingefroren
- Sauerkraut gemacht
- ein Arsch hat mein Auto angefahren und ist abgehauen. Stinkt mir zwar, aber kostet mit Smartrepair nicht die Welt. Und das Beste ist: Der Arsch hat auch einen fetten Kratzer bin der Stoßstange 😂😂😂😂😂😂😂😂!

QDarts: A Quantum Dot Array Transition Simulator for finding charge transitions in the presence of finite tunnel couplings, non-constant charging energies and sensor dots
We present QDarts, an efficient simulator for realistic charge stability diagrams of quantum dot array (QDA) devices in equilibrium states. It allows for pinpointing the location of concrete charge states and their transitions in a high-dimensional voltage space (via arbitrary two-dimensional cuts through it), and includes effects of finite tunnel coupling, non-constant charging energy and a simulation of noisy sensor dots. These features enable close matching of various experimental results in…

Positive values of non-homogeneous quadratic forms of type (1,4): A conjecture of Bambah, Dumir and Hans-Gill
Let $Q(x_1, \cdots,x_n)$ be a real indefinite quadratic form of the type $(r,s)$, $n=r+s$, signature $σ=r-s$ and determinant $D\neq 0$. Let $Γ_{r,n-r}$ denote the infimum of all numbers $Γ$ such that for any real numbers $c_1, c_2 ,\cdots, c_n$ there exist integers $x_1, x_ 2,\cdots, x_n$ satisfying $$0< Q(x_1+c_1,x_2+c_2,\cdots,x_n+c_n)\leq (Γ|D|)^{1/n}.$$ All the values of $Γ_{r,n-r}$ are known except for $Γ_{1,4}$. Earlier it was shown that $8\leq Γ_{1,4}<12$. It is conjectu…
