A branch group with unsolvable conjugacy problem
We prove that every finitely generated residually finite group $G$ can be embedded in a finitely generated branch group $Γ$ such that two elements in $G$ are conjugate in $G$ if and only if they are conjugate in $Γ$. As an application we construct a finitely generated branch group with solvable word problem and unsolvable conjugacy problem and thereby answer a question of Bartholdi, Grigorchuk, and Šunik.

Atacama Cosmology Telescope: Constraints on the Millimetre Flux of the Crab Pulsar
Millimeter-wave observations of pulsars, while crucial for understanding their emission mechanisms, remain scarce. We demonstrate that high-precision cosmic microwave background (CMB) experiments like the Atacama Cosmology Telescope (ACT), though designed for cosmology, offer a unique capability for such time-domain science due to their high cadence and broad sky coverage in millimeter bands. While previous ACT searches have focused on transients lasting minutes or longer, we develop and valida…

Visible Light Communication for Vehicular Networks: A Tutorial
The advent of the fifth-generation technology promises to bring about more vertical applications and emerging services that include vehicular networks and intelligent transportation systems (ITSs). To achieve their vision of real-time and safetyapplications, vehicular networks rely on short-range to medium-range communications. One emerging technology that aims to provide reliability and high-data rate in short-range communications is the visible light communications (VLC). Due to its remarkabl…

Magma ocean interactions can explain JWST observations of the sub-Neptune TOI-270 d
Sub-Neptunes with substantial atmospheres may possess magma oceans in contact with the overlying gas, with chemical interactions between the atmosphere and magma playing an important role in shaping atmospheric composition. Early JWST observations have found high abundances of carbon- and oxygen-bearing molecules in a number of sub-Neptune atmospheres, which may result from processes including accretion of icy material at formation or magma-atmosphere interactions. Previous work examining the e…

Accurate Small-Signal Modeling of Digitally Controlled Buck Converters with ADC-PWM Synchronization
Digital control has become increasingly widespread in modern power electronic converters. When acquiring feedback signals such as the inductor current, synchronizing the analog-to-digital converter (ADC) with the digital pulse-width modulator (DPWM) is commonly employed to accurately track their steady-state average. However, the small-signal implications of such synchronization have not been investigated. This paper presents an exact small-signal model for digitally controlled buck converters …

Ideology, institutions, and economic growth: panel evidence 1995 2022
Does it matter whether a government is "left wing" or "right wing" for economic growth? Using a panel of 113 countries (1995 2022), we combine: (i) the economic ideology of the executive branch (V Dem), (ii) the disaggregated institutional quality of the economic freedom index (Heritage), separating a core institutional block (HN: property rights, government integrity, judicial effectiveness) from a block of liberalization policies (HL: trade/financial openness, regulatory efficiency, size of g…

Dynamical Tension Strings with Target Scale Symmetry producing DE, DM and why 4D?
In the modified measure formulation string or branes the tension appear as an additional dynamical degree of freedom . Furthermore in the presence of an additional background scalar field that couples to the strings and locally changes the tension, the tension field really dynamical and the theory has an intrinsic target space scale symmetry. When many types of strings probing the same region of space are considered this tension scalar is constrained by the requirement of quantum conformal inva…
