text: "\r\n Introduction\r\n
\ Age-related changes in brain signal complexity are
associated with cognitive decline and reduced neural adaptivity in older adults.
Exergaming offers a promising prophylactic intervention combining physical and
cognitive training. The aim of the present study was to assess how exergaming
alters the temporal trajectory of brain signal complexity at rest and during gameplay
in older adults.\r\n \r\n \r\n
\ Methods\r\n Twenty-eight
healthy older adults participated in a 4-week exergaming intervention. Electroencephalography
was recorded using 64 electrodes at rest (pre- and post-intervention) and during
exergaming (pre-, mid-, and post-intervention). Brain signal complexity was quantified
using multiscale entropy across 64 time scales on preprocessed signals.\r\n
\ \r\n \r\n Results\r\n
\ Post-intervention resting-state analysis revealed
significant reductions at fine and increases at coarse scales in frontal, central,
and posterior entropy. During gameplay, entropy declined widespread by mid-intervention,
particularly at coarse scales over frontal, central and temporal regions. From
mid- to post-intervention, the decline narrowed leaving a net pre-to-post reduction
concentrated at coarse scales in these regions.\r\n \r\n
\ \r\n Discussion\r\n
\ Resting-state changes indicated a shift toward a younger
brain profile, characterized by a transition from age-related increases in local
processing to enhanced distributed processing, which may potentially mitigate
the rise in neural modularity associated with aging. During gameplay, brain signal
complexity decreased in week 2, followed by a modest change by week 4, consistent
with the framework in which complexity initially streamlines and then adjusts
toward a task-specific optimum. These findings suggest that exergaming can beneficially
modulate brain complexity in older adults, offering the potential to reduce age-related
neural decline and support healthy brain aging.\r\n "

text: "Abstract\r\n A fundamental
equation of state for tetramethoxysilane (TMOS) is developed based on the available
experimental data. In addition, new density and speed of sound measurements were
performed specifically for this work to improve the database. Owing to the limited
overall data set, additional thermodynamic properties were analyzed to support
the fitting procedure and ensure physically consistent behavior. Modified representations
of thermodynamic properties that are typically employed in the fitting procedure
were introduced to facilitate the application of constraints. The resulting model
provides a consistent description of the thermodynamic properties of TMOS."

text: "After nearly two decades of research, the question of a quantum PCP theorem\r\nfor
quantum Constraint Satisfaction Problems (CSPs) remains wide open. As a\r\nresult,
proving QMA-hardness of approximation for ground state energy\r\nestimation has
remained elusive. Recently, it was shown [Bittel, Gharibian,\r\nKliesch, CCC 2023]
that a natural problem involving variational quantum\r\ncircuits is QCMA-hard
to approximate within ratio N^(1-eps) for any eps > 0 and\r\nN the input size.
Unfortunately, this problem was not related to quantum CSPs,\r\nleaving the question
of hardness of approximation for quantum CSPs open. In\r\nthis work, we show that
if instead of focusing on ground state energies, one\r\nconsiders computing properties
of the ground space, QCMA-hardness of computing\r\nground space properties can
be shown. In particular, we show that it is (1)\r\nQCMA-complete within ratio
N^(1-eps) to approximate the Ground State\r\nConnectivity problem (GSCON), and
(2) QCMA-hard within the same ratio to\r\nestimate the amount of entanglement
of a local Hamiltonian's ground state,\r\ndenoted Ground State Entanglement (GSE).
As a bonus, a simplification of our\r\nconstruction yields NP-completeness of
approximation for a natural k-SAT\r\nreconfiguration problem, to be contrasted
with the recent PCP-based PSPACE\r\nhardness of approximation results for a different
definition of k-SAT\r\nreconfiguration [Karthik C.S. and Manurangsi, 2023, and
Hirahara, Ohsaka, STOC\r\n2024]."

text: Expanding renewable energy sources is essential for a sustainable energy supply
but challenges grid stability, as the volatility of solar and wind causes periods
of over- and undersupply. Private households are central to this transition, combining
dynamic consumption with decentralised generation. This paper presents a multi-agent
microgrid simulation built on the Mesa framework, focusing on the heterogeneous
objectives and technological capabilities of residential participants. Households
are modelled as autonomous agents with individual strategies, while a dedicated
“grid agent” represents the distribution system operator and regulates the microgrid
in a grid-supportive manner. The emission factor serves as the key indicator for
grid-friendly behaviour. Results show that in summer, unmanaged PV feed-in from
heterogeneous households causes substantial grid stress and balancing effort for
the distribution system operator. Dynamic electricity prices can incentivise grid-friendly
dispatch, but their effectiveness depends on the correlation between price signals
and renewable availability and cannot guarantee grid-supportive behaviour alone.
The grid agent reliably improves the grid-supportive coefficient, yet its operating
strategy, for instance additional peak-reduction objectives, can interfere with
price-based incentives. Effective demand-side management therefore requires careful
analysis of stakeholder interactions. Building on this insight, thepaper provides
a basic framework for the design, implementation, and assessment of both integrated
and individual energy management strategies within a microgrid environment. By
simulating the dynamic interactions among system participants and strategies,
it enables comprehensive evaluation of their collective impact on the grid, supporting
the development of robust solutions for future electricity networks.

text: The reduction of CO2-emissions in the chemical industry is essential
to meet European climate targets. Particularly, the reliance on fossil fuels for
process heat supply is a key factor for CO2-emissions. Electrically driven compression
heat pumps are a promising option to reduce fossil fuel consumption by upgrading
low-temperature waste heat to a higher temperature level, provided that low-carbon
electricity is available. However, the integration of heat pumps into chemical
utility systems remains a challenge due to economic constraints and the high complexity
associated with site-wide heat integration and retrofit of existing structures.
This work presents a mixed-integer linear programming (MILP) approach for the
optimization of utility systems with integrated heat pumps. To address computational
complexity, candidate utility temperature levels are pre-selected, and feasible
heat pump coefficients of performance (COP) are precomputed. The framework is
applied to both greenfield and retrofit scenarios for a synthetic case study consisting
of 400 process streams. In the greenfield scenario, optimal utility temperature
levels and heat pump integration configurations are identified. For the retrofit
scenario, temperature levels of an existing utility system are modified to reduce
total annual costs (TAC). Additionally, sensitivity analysis is conducted to assess
the influence of key economic and environmental parameters. The presented case
studies demonstrate short solution times, highlighting the suitability of the
proposed framework for screening studies and systematic sensitivity analyses in
early-stage design and retrofit applications.

text: Heat pumps offer the possibility of reducing CO2-emissions in the
chemical industry. However, the integration of heat pumps, especially in non-continuous
processes, faces several challenges. Energy storage facilitates a way to enhance
heat integration by providing a continuous supply of heat flows. By doing so,
the question arises as to whether this implementation should be applied to the
process or to the utility level. At the process level, there is usually more freedom,
as one is not bound by the existing temperature levels of the utility system,
which are mostly difficult to retrofit. Therefore, this study presents an approach
that generates heat integration concepts at the process level based on two different
criteria. These criteria influence which process streams are grouped for a storage
implementation and therefore influence the heat integration. The aim is to maintain
the heat flows as continuous as possible by integrated heat storages. Finally,
the possible heat integration concept is evaluated in terms of energy efficiency
by a know method for continuous process streams, here the pinch analysis.

text: We examine the relation between voluntary audit and the cost of debt in private
firms. We use a sample of 7420 small private firms operating in the period 2006-2022
that are not subject to mandatory audits. Firms self-select into voluntary audits
because of the economic setting (e.g., ownership complexity, export, subsidiary
status) or because firm fundamentals limit their access to financial debt. In
the outcome analyses, we find that voluntary audits result in higher, rather than
lower, interest rates with increases ranging from approximately 1.7 percentage
points, but going higher depending on the exact specification. This effect is
present regardless of the perceived audit quality (Big-4 vs. non-Big-4), consistent
across auditor types. Audited firms’ earnings are less informative about future
operating performance. Voluntary audits facilitate access to financial debt for
high-risk firms. The price paid is reflected in higher interest rates for voluntary
audits – firms with higher information/fundamental risk.
