“A wind of change” in recreational fisheries? Recreational fishermen and wind farms: current use and perception
Offshore wind farms create opportunities for recreational fishermen in Belgium, since the presence of hard substrates and the closure for trawling create a favorable habitat for fish. After the construction in 2008, a concentration of anglers was observed in the vicinity of the first wind farm during monitoring. In the following years, however, the interest of anglers for the wind farms seemed to disappear. To elucidate the evolution in the relation between recreational angling intensity and wind farms, this study aimed to assess how Belgian recreational fishermen perceive wind farms, how often they visit them and why, and which fish species they (expect to) catch. Data were derived from the annual DCF survey for recreational fishermen. Less than 2% of the sea anglers reported to go fishing in the larger wind farm area, even when 30 to 40 percent of the respondents either expected more fish, bigger fish or other fish species. The main reasons to stay away from wind farms is because entering the wind farms themselves is not allowed, because the distance to the wind farms is relatively large, because charter vessels do not offer fish trips to wind farms, and because wind farms are protection zones and nursery areas for fish. 40% of the respondents would consider fishing inside wind farms if it were allowed, mainly because they expect more or other fish. This is a clear indication that the enforcement of wind farm closure for fisheries and shipping is vital when aiming at the creation and/or restoration of nursing grounds in the area. However, the large distance to the wind farms will probably continue to limit fishing pressure, even if wind farms would (partly) be opened for recreational fisheries
Scientific Expertise in Child Protection Policies and Juvenile Justice Practices in Twentieth-Century Belgium
Modern society cannot function without experts and yet we increasingly question the authority of those who advise us. The essays in this collection explore our reliance on experts within a historical context and across a wide range of fields, including agriculture, engineering, health sciences and labour management. Contributors argue that experts were highly aware of their audiences and used performance to gain both scientific and popular support
Comprehensive transcriptome-wide analysis of spliceopathy correction of myotonic dystrophy using CRISPR-Cas9 in iPSCs-derived cardiomyocytes
CTG repeat expansion (CTGexp) is associated with aberrant
alternate splicing that contributes to cardiac dysfunction in
myotonic dystrophy type 1 (DM1). Excision of this CTGexp
repeat using CRISPR-Cas resulted in the disappearance of
punctate ribonuclear foci in cardiomyocyte-like cells derived
from DM1-induced pluripotent stem cells (iPSCs). This was
associated with correction of the underlying spliceopathy as
determined by RNA sequencing and alternate splicing analysis.
Certain genes were of particular interest due to their role in cardiac
development, maturation, and function (TPM4, CYP2J2,
DMD, MBNL3, CACNA1H, ROCK2, ACTB) or their association
with splicing (SMN2, GCFC2, MBNL3). Moreover, while
comparing isogenic CRISPR-Cas9-corrected versus non-corrected
DM1 cardiomyocytes, a prominent difference in the
splicing pattern for a number of candidate genes was apparent
pertaining to genes that are associated with cardiac function
(TNNT, TNNT2, TTN, TPM1, SYNE1, CACNA1A, MTMR1,
NEBL, TPM1), cellular signaling (NCOR2, CLIP1, LRRFIP2,
CLASP1, CAMK2G), and other DM1-related genes (i.e.,
NUMA1, MBNL2, LDB3) in addition to the disease-causing
DMPK gene itself. Subsequent validation using a selected
gene subset, including MBNL1, MBNL2, INSR, ADD3, and
CRTC2, further confirmed correction of the spliceopathy
following CTGexp repeat excision. To our knowledge, the present
study provides the first comprehensive unbiased transcriptome-
wide analysis of the differential splicing landscape in
DM1 patient-derived cardiac cells after excision of the CTGexp
repeat using CRISPR-Cas9, showing reversal of the abnormal
cardiac spliceopathy in DM1
Entanglement-assisted quantum low-density parity-check codes
This paper develops a general method for constructing entanglement-assisted
quantum low-density parity-check (LDPC) codes, which is based on combinatorial
design theory. Explicit constructions are given for entanglement-assisted
quantum error-correcting codes (EAQECCs) with many desirable properties. These
properties include the requirement of only one initial entanglement bit, high
error correction performance, high rates, and low decoding complexity. The
proposed method produces infinitely many new codes with a wide variety of
parameters and entanglement requirements. Our framework encompasses various
codes including the previously known entanglement-assisted quantum LDPC codes
having the best error correction performance and many new codes with better
block error rates in simulations over the depolarizing channel. We also
determine important parameters of several well-known classes of quantum and
classical LDPC codes for previously unsettled cases.Comment: 20 pages, 5 figures. Final version appearing in Physical Review
