Precision Fabrication and Development of Charging and Testing Methods of Fixed-Abrasive Lapping Plates [PDF]
, 2003 The recording head industry is one of the dominant users of advanced ceramics such as alumina, silicon nitride, silicon carbide and AlTiC. The high hardness of these materials makes diamond the optimal abrasive for machining.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Case Studies in Construction Materials, 2022 For longer spans of reinforced concrete elements, design codes dictate the use of sufficient lap splice length. Insufficient lap splice length decreases the flexural strength and ductility of reinforced concrete (RC) beams, while fiber addition improves their load-carrying capacity, ductility, and durability.

On repetitions of blocks in binary sequences [PDF]
, 1976 The following is proved: (1) There exists an infinite binary sequence having no triple repetitions, and having no repetitions of length 4 or greater. (2) Binary sequences having no triple repetitions and having no repetitions of length 3 or greater are ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Studies on the Dynamic Analysis and the Lapping Tracks in the Ball-Lapping Systems [PDF]
, 2006 A general closed-form analytical solution is derived for the lapping tracks with its kinematics for the concentric V-groove lapping system. The lapping tracks on the ball surface for the three contact points are fixed circles, and their lengths of the ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Soldering sheets using soft solders
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 The paper contains strength tests results of joints soldered using lead and leadless soft solders. For tests lead solders types Pb60Sn40 and Sn60Pb40 and leadless soft solders types Sn95.5Ag3.8Cu0.7 and Sn96Ag4 were used.

Comparative investigations of the surface damage of monocrystalline silicon wafers by scanning infrared reflection examination and raman spectroscopy [PDF]
, 2022 S.466-471Mechanical preparation of mono- and multicrystalline silicon wafers by sawing, lapping, or grinding damages the surface. Depending on the mechanical impact of the treatment different degrees of damage structures occur.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
