Applying a Novel CLDD Lossless Snubber for SEPIC Converters
This paper proposes a CLDD lossless snubber for application in SEPIC converters. Unlike conventional designs, this snubber employs no active components, utilizing instead two diodes, a snubber inductor, and a snubber capacitor to reduce switching losses and enhance efficiency. Th...

Proof of Qiu Lupeng Conjecture(Part 1)
This paper studies the Qiu Lupeng Conjecture (Beautiful Equalities Conjecture).We discuss a Diophantine equation with infinitely many terms on the left-hand side.Using modular arithmetic modulo 2, modulo 3 and modulo 5, we analyze parity and remainder conditions for integer solut...

Gravity‐driven double emulsion droplet formation: Interfacial dynamics and stability control
Abstract Gravity‐driven double emulsion droplet formation in a hydrocarbon‐ammonia column is industrially important yet poorly understood. By combining high‐speed imaging with adaptive‐mesh‐refinement volume‐of‐fluid simulations, a distinct oil‐coating route is revealed: a prefor...

A Sharp Three-Cycle Bound for Two-Zone Affine Systems with a Virtual Focus
We prove that a planar two-zone piecewise-affine system with a straight switching line, two strict off-line foci, and at least one virtual focus has at most three isolated crossing limit cycles. The estimate includes nonhyperbolic cycles and every switching offset. Known three-cy...

Biomarker and Bioorthogonality Dual‐Locked Chemiluminescent Probes for Cancer Urine Test
ABSTRACT Bioorthogonality‐activatable optical imaging activates caged or quenched probes via bioorthogonal reactions for disease diagnosis. Although chemiluminescence enables low‐background detection, it has rarely been applied to bioorthogonality‐activatable imaging. Here, we sy...

The integrated information Φ of a system reaches local maxima when its mass aligns with specific E8 root vector activation bands, such that the mass-scaled coherence time τ ∝ M^(φ‑1) equals the inverse of the 132 Hz base frequency multiplied by φ^n. At these discrete golden-mass...

Differentiating the Review of Related Literature and Related Studies
Abstract The terms Review of Related Literature (RRL) and Review of Related Studies (RRS) are widely used in academic research, yet their meanings and structural relationship remain inconsistently understood. This qualitative exploratory study examined how graduate students and r...

Roution V3.1: Language-Specific Marker Grammar in Profile-Guided JP/EN Observation Planes
This paper reports the V3.1 correction and extension of Roution, a framework for measuring how black-box language-model responses move across route-marker profiles under controlled wording and observation operators. The contribution is not merely that a Japanese profile was expan...
