Textile manufacturing in eight developing countries:How far does the business environment explain firms' productive inefficiency? [PDF]

Production frontiers and inefficiency determinants are estimated by using stochastic models. Textile manufacturing is considered for a sample of eight developing countries encompassing about one thousand firms.

Local magnetic anisotropy in BaFe$_2$As$_2$: a polarized inelastic neutron scattering study

, 2012
The anisotropy of the magnetic excitations in BaFe$_2$As$_2$ was studied by polarized inelastic neutron scattering which allows one to separate the components of the magnetic response. Despite the in-plane orientation of the static ordered moment we find

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Random sampling of plane partitions

, 2009
This article presents uniform random generators of plane partitions according to the size (the number of cubes in the 3D interpretation). Combining a bijection of Pak with the method of Boltzmann sampling, we obtain random samplers that are slightly ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Technical Efficiency Measurement within the Ivorian Manufacturing Sector: a Data Envelopment Analysis Approach [PDF]

The African industrial structure is characterised by a strong firm-size heterogeneity with a co-existence of small if not micro-enterprises of the informal sector and large formal organisations operating with a modern technology.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Reorientation of Spin Density Waves in Cr(001) Films induced by Fe(001) Cap Layers

, 1998
Proximity effects of 20 \AA thin Fe layers on the spin density waves (SDWs) in epitaxial Cr(001) films are revealed by neutron scattering. Unlike in bulk Cr we observe a SDW with its wave vector Q pointing along only one {100} direction which depends ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

TEACHING BASIC ELEMENTS IN DESCRIPTIVE GEOMETRY – LINE INTERSECTING A PLANE

Journal of Industrial Design and Engineering Graphics
The paper presents applications developed for teaching descriptive geometry. The aim of the applications presented is the understanding of the basic elements of the descriptive geometry – the relative positions of a straight line and a plane and they ...
