Evolutionary Properties of Neural Networks: Exploration of Robustness and Evolvability in the Genotype-Phenotype Map

Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. While both robustness and evolvability are necessary, embracing them simultaneously seemingly leads to an inherent conflict due

The Effect of Diversity Initiatives and Meritocratic Values on Belief in Anti-Black Discrimination

This experimental study investigates the effect of diversity initiatives on White individuals' perception of discrimination against minorities and whether this relationship interacts with their meritocratic values. With an increased global emphasis on diversity and inclusion, organizations strive to reduce discrimination and instead promote a culture that values diversity. However, the effecti

Intraabdominal and retroperitoneal soft-tissue sarcomas - Surgical treatment and outcomes

BACKGROUND: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.METHODS: A retrospective review of consecutive patients (n = 107) with IaRS treated at single center from 2

Lignin-degrading enzymes: an overview

Lignin is the second most abundant naturally produced organic polymer on earth. Lignin‐modifying enzymes (LMEs) are produced by the white‐rot fungi as products of secondary metabolism, since lignin degradation does not provide any energy to the fungus. The main oxidative enzymes include the peroxidases‐lignin peroxidase (LiP) (diarylpropane: oxygen, hydrogen peroxide oxidoreductase), manganese per

Flow cytometric evaluation of platelet activation in blood collected into EDTA vs. Diatube‐H, a sodium citrate solution supplemented with theophylline, adenosine, and dipyridamole

With platelet activation, there is modulation of platelet surface molecule expression. In flow cytometric analyses of in vivo platelet activation, results are often confounded by activation induced in vitro by the preparative procedures. It is particularly important therefore to prevent or retard platelet activation as soon as possible after withdrawal of the blood sample. Taking blood into parafo

Frequency-selective wallpaper for indoor interference reduction and MIMO capacity improvement

This paper presents the design and features of frequency-selective wallpaper-based on periodic and symmetric metallic hexagons-intended to be attached to standard walls for filtering out 5GHz signals (e.g., IEEE 802.11a systems)without blocking other selected radio communication services (e.g., cellular mobile communication signals). It analyzes the characteristics of the radio channel-as found wi

Impact of variations in residential use of household electricity on the energy and power demand for space heating – Variations from measurements in 1000 apartments

Low energy buildings are usually characterized by a very well insulated building envelope and an efficient ventilation system that makes use of the heat in the exhaust air. Internal heat gains from residents and their use of appliances can cover the heating demand to a certain extent. The magnitude of internal heat gains that cover demand are often modelled in a simplified way and thus can be asso

Psychiatric manifestations of neurologic diseases : Etiology, phenomenology, and treatment

Understanding the etiology and meaning of behavioral symptomatology in the context of neurologic disease, and choosing the most effective intervention is a vexing task. This introduction summarizes the history of our understanding of the relationship between behavioral symptoms and primary neurologic conditions, and considers the ways in which both psychiatric and neurologic disorders occurring si

The SAGA so far : Reading the history of the Galaxy with asteroseismology

Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When this information is coupled with classical determinations of stellar parameters, such as metallicities, effective temperatures and angular diameters, powerful new diagnostics for stellar and Galactic studies can be obtained. The ongoing Strö

Swiss pendulous hammer for decoupling measurement of service equipment in wooden multi-storey building

The latest Swiss standard SIA181 (6-2006 edition [1]) introduces a new methodology regarding the tests to be performed in new constructions for assessing noise induced by the manipulation of service equipment in bathrooms and kitchens. However, this method has been developed especially for massive constructions. In this study, we are investigating the relevance of such method for timber frame buil

Prepatterning in the stem cell compartment

The mechanism by which an apparently uniform population of cells can generate a heterogeneous population of differentiated derivatives is a fundamental aspect of pluripotent and multipotent stem cell behaviour. One possibility is that the environment and the differentiation cues to which the cells are exposed are not uniform. An alternative, but not mutually exclusive possibility is that the obser

Lactobacillus reuteri NAD(P)H oxidase : Properties and coexpression with propanediol-utilization enzymes for enhancing 3-hydroxypropionic acid production from 3-hydroxypropionaldehyde

Lactobacillus reuteri metabolizes glycerol through propanediol-utilization (Pdu) pathway to 1,3-propanediol (1,3-PD) via 3-hydroxypropionaldehyde (3-HPA) as intermediate. In the resting cells, the oxidized co-factor obtained in the reaction is regenerated by simultaneous oxidation of 3-HPA to 3-hydroxypropionic acid (3-HP) using propionaldehyde dehydrogenase (PduP), phosphotransacylase (PduL) and

Stability of Linear Systems under Extended Weakly-Hard Constraints

Control systems can show robustness to many events, like disturbances and model inaccuracies. It is natural to speculate that they are also robust to sporadic deadline misses when implemented as digital tasks on an embedded platform. This paper proposes a comprehensive stability analysis for control systems subject to deadline misses, leveraging a new formulation to describe the patterns experienc

Speed and concentration of the covering time for structured coupon collectors

Let V be an n-set, and let X be a random variable taking values in the power-set of V . Suppose we are given a sequence of random coupons X1 , X2 , ..., where the Xi are independent random variables with distribution given by X. The covering time T is the smallest integer t ≥ 0 such that the union of the first t Xi's equal V . The distribution of T is important in many applications in combinatoria

Predictive Force-Centric Emergency Collision Avoidance

A controller for critical vehicle maneuvering is proposed that avoids obstacles and keeps the vehicle on the road while achieving heavy braking. It operates at the limit of friction and is structured in two main steps: a motion-planning step based on receding-horizon planning to obtain acceleration-vector references, and a low-level controller for following these acceleration references and transf
