Yard Management: Identification and Evaluation of Critical Sub-processes with AHP
No full textYard management is crucial for logistics and transport operations due to the high influence towards smooth and efficient intralogistics on dedicated depot sites of logistics service providers. Yet, this field has interesting new insights to offer, especially regarding prioritizing and decision-making concepts with the support of Multi-Criteria Decision Analysis (MCDA) tools. Within this publication five critical yard sub-processes are identified and prioritized with the AHP methodology in the following order: management of the shunting system, registration at the gateway, allocation of trucks to gates/parking spaces, removal of a transport unit from the gate and exit control
Implementation of an experimentally feasible controlled-phase gate on two blockaded Rydberg atoms
No full textWe investigate the implementation of a controlled-Z gate on a pair of Rydberg atoms in spatially separated dipole traps where the joint excitation of both atoms into the Rydberg level is strongly suppressed (the Rydberg blockade). We follow the adiabatic gate scheme of Jaksch et al. [D. Jaksch, J. I. Cirac, P. Zoller, S. L. Rolston, R. Côté, and M. D. Lukin, Phys. Rev. Lett. 85, 2208 (2000)PRLTAO0031-900710.1103/PhysRevLett.85.2208], where the pair of atoms is coherently excited using lasers, and apply it to the experimental setup outlined by Gaëtan et al. [A. Gaëtan, Y. Miroshnychenko, T. Wilk, A. Chotia, M. Viteau, D. Comparat, P. Pillet, A. Browaeys, and P. Grangier, Nat. Phys. 5, 115 (2009)NPAHAX1745-247310.1038/nphys1183]. We apply optimization to the experimental parameters to improve gate fidelity and consider the impact of several experimental constraints on the gate success. © 2014 American Physical Society
Códigos de Reed-Muller
No full textThe Reed-Muller codes were discovered by David Eugene Muller and decoded by Irving Stoy Reed in 1954. Such codes belong to the linear code family and are widely used nowadays, mainly for their simple and efficient decoding algorithm. There are several ways to define Reed-Muller codes. In this work, we present, in a clear and simple way, a recursive definition for all Reed-Muller codes of order r \in N, denoted by R (r, m), where 0 <= r <= m, m \in N. Using this definition, we show the main parameters: length, number of elements and minimum distance of first-order Reed-Muller codes, R(1, m) for all m \in N. In addition, we present an application of the first-order codes in a National Aeronautics and Space Administration (NASA) space program.Os códigos de Reed-Muller foram descobertos por David Eugene Muller e decodificados por Irving Stoy Reed em 1954.

Weighing evidence

Advocate, 32(3):60-61.The original publication is available at https://www.sabar.co.za/law-journals/Often different pieces of evidence of different degrees of credibility are submitted in legal proceedings. Then a court “weighs” the evidence and arrives at a conclusion. But how should evidence be weighed? The use of probability theory comes to mind. Examples in this article illustrate this approach.Post prin
Weak Muller acceptance conditions for tree automata
No full textOver the last decades the theory of automata on infinite objects has been an important source of tools for the specification andthe verification of computer programs. Trees are more suitable than words to model nondeterminism and concurrency. In the literature, there are several examples of acceptance conditions that have been proposed for automata on infinite words and then have been fruitfully extended to infinite trees. The type of acceptance condition can influence both the succinctness of the language acceptors and the computational complexity of the decision problems. Here we consider, relatively to automata on infinite trees, two acceptance conditions that are obtained by relaxing Muller acceptance condition: the Landweber and the Muller-Superset conditions. We prove that Muller-Superset tree automata accept the same class of languages as Büchi tree automata. Also, we show that for such languages the minimal Muller-Superset acceptor is at least as succinct as the minimal Büchi acceptor and, in some cases, it can be exponentially more succinct. Landweber tree automata, instead, define a class of languages that is not comparable with that defined by Büchi tree automata. The main result we prove is that the emptiness problem for this class of automata is decidable in polynomial time, andthus we extendthe class of automata with a tractable emptiness problem

Males can easily be distinguished from other species within the globuliseta- group, and other nonglobular species by the seemingly unique apically globular seta on the antennal pedicel (Fig. 7) in combination with well-developed and normally appearing thoracic and leg setae and setulae. Females have the supramedian posterior seta on the mid tibia absent, and tergite 6 as two relatively slender plates (Fig. 24), compared with females of C. flagelliseta (the only other known female in the group) that have the seta present, and tergite 6 as a broad, fused plate (Fig. 26). Males and females with preapical dorsal and anterodorsal setae on hind tibia, unlike the other species in the group.Published as part of Muller, Burgert S. & Midgley, John M., 2022, How strange: Coenosia curiosa sp. nov.

Contribution of potassium channels to myogenic response in skeletal muscle arterioles: effects of age and fiber type
No full textIn isolated skeletal muscle arterioles, increasing transmural pressure causes an
increase in constriction. This active myogenic response varies with age and fiber type.
Increased transmural pressure activates both Ca2+-activated (KCa) potassium channels and
voltage-dependent (Kv) potassium channels; these channels have a role in the negativefeedback
pathways that modulate depolarization and myogenic constriction. We tested
the hypothesis that increased KCa channel and Kv channel activity contribute to reduced
myogenic responsiveness in skeletal muscle arterioles of aged rats. 1A arterioles were
isolated from soleus, an oxidative muscle, and superficial gastrocnemius, a glycolytic
muscle, of young (4 mos) and aged (24 mos) Fischer 344 rats. Myogenic responses were
assessed by increasing intraluminal pressure (0-140 cm H2O) in increments of 20cm H2O.
Vasoconstrictor response were determined in response to increasing concentrations of the
KCa channel blocker, charybdotoxin (CTX; 10-10 to 10-7 M) and the Kv channel blocker,
4-Aminopyridine (4-AP; 10-5 to 10-2 M). To determine the role of potassium channels in
modulating the myogenic response, cannulated arterioles from soleus and gastrocnemius
were incubated with CTX (50 nM) and 4-AP (5mM) for 15 minutes prior to evaluation of
the myogenic response. Increased Kv channel activity contributes to reduced myogenic constriction in soleus and gastrocnemius muscle arterioles from aged rats. In soleus
muscle arterioles, KCa channel activity opposes myogenic tone in young but not old rats.
In gastrocnemius muscle arterioles, treatment with CTX did not eliminate age-related
differences in the myogenic response, and the KCa channel contribution to myogenic tone
was, in fact, greater arterioles from young as compared to old rats. Kv channels contribute
to greater myogenic constriction in soleus arterioles, KCa channels appear to be more
active in gastrocnemius muscle arterioles as compared to soleus muscle arterioles.
Therefore Kv and KCa channels are tonically active in skeletal muscle arterioles,
contributing to a hyperpolarizing force that opposes myogenic constriction. Furthermore,
increased Kv channel activity contributes to the age-related reduction of myogenic
constriction in soleus and gastrocnemius muscle arterioles
Determining the Weight Spectrum of the Reed--Muller Codes RM(m-6,m)
No full textThe weight spectra of the Reed-Muller codes were unknown for
. In IEEE Trans. Inform. Theory 2024, Carlet determined the weight
spectrum of for using the Maiorana-McFarland construction,
where the result was tried to be extended to , but many problems
occurred and much work needed to be done. In this paper, we propose a novel way
of constructing Reed--Muller codewords and determine the weight spectrum of
for , which gives a positive answer to an open question on
the weight spectrum of for . Moreover, we put forward a
conjecture and verify it for some cases. If the conjecture is true, then that
open question can be completely solved
