This report outlines the customisation opportunities for IUCLID version 6. It also gives an overview of what IUCLID offers to regulatory bodies and industry as a key application to record, store, maintain and exchange data on chemicals. IUCLID is used in a variety of countries and regulatory contexts, therefore the report describes to which extent it is customisable to facilitate the management of chemical data across these contexts.

This work considers the scaling properties characterizing the hyperuniformity (or anti-hyperuniformity) of long-wavelength fluctuations in a broad class of one-dimensional substitution tilings. A simple argument is presented which predicts the exponent α governing the scaling of Fourier intensities at small wavenumbers, tilings with α > 0 being hyperuniform, and numerical computations confirm that the predictions are accurate for quasiperiodic tilings, tilings with singular continuous spectra and limit-periodic tilings. Quasiperiodic or singular continuous cases can be constructed with α arbitrarily close to any given value between −1 and 3. Limit-periodic tilings can be constructed with α between −1 and 1 or with Fourier intensities that approach zero faster than any power law.

Need to implement containment plan uniformly across the country: Lav Agarwal, MoHFW

We show that every 4-uniform hypergraph with $n$ vertices and minimum pair degree at least $(5/9+o(1))n^2/2$ contains a tight Hamiltonian cycle. This degree condition is asymptotically optimal.

Consider an infinite planar graph with uniform polynomial growth of degree d > 2. Many examples of such graphs exhibit similar geometric and spectral properties, and it has been conjectured that this is necessary. We present a family of counterexamples. In particular, we show that for every rational d > 2, there is a planar graph with uniform polynomial growth of degree d on which the random walk is transient, disproving a conjecture of Benjamini (2011).

By a well-known theorem of Benjamini and Schramm, such a graph cannot be a unimodular random graph. We also give examples of unimodular random planar graphs of uniform polynomial growth with unexpected properties. For instance, graphs of (almost sure) uniform polynomial growth of every rational degree d > 2 for which the speed exponent of the walk is larger than 1/d, and in which the complements of all balls are connected. This resolves negatively two questions of Benjamini and Papasoglou (2011).

A method for mask data preparation or mask process correction is disclosed in which a set of charged particle beam shots is determined which is capable of forming a pattern on a surface, wherein critical dimension uniformity (CDU) of the pattern is optimized. In some embodiments the CDU is optimized by varying at least two factors. In other embodiments, model-based techniques are used. In yet other embodiments, the surface is a reticle to be used in an optical lithographic process to form a pattern on a wafer, and CDU on the wafer is optimized.

A method is described for improving the uniformity over a predetermined substrate area of a spectral response of photonic devices fabricated in a thin device layer. The method includes (i) establishing an initial device layer thickness map for the predetermined area, (ii) establishing a linewidth map for the predetermined area, and (iii) establishing an etch depth map for the predetermined area. The method further includes, based on the initial device layer thickness map, the linewidth map and the etch depth map, calculating an optimal device layer thickness map and a corresponding thickness correction map for the predetermined substrate area taking into account photonic device design data. Still further, the method includes performing a location specific corrective etch process in accordance with the thickness correction map.

When forming sophisticated semiconductor-based gate electrode structures of transistors, the pre-doping of one type of gate electrode structure may be accomplished after the actual patterning of the electrode material by using an appropriate mask or fill material for covering the active regions and using a lithography mask. In this manner, a high degree of flexibility is provided with respect to selecting an appropriate patterning regime, while at the same time a uniform and superior cross-sectional shape for any type of gate electrode structure is obtained.

A light guide plate includes a main body and a number of micro protrusions. The main body includes a light emitting surface, a bottom surface, and a light incident surface. The bottom surface is opposite to the light emitting surface. The light incident surface connects the light emitting surface and the bottom surface. The protrusions are randomly positioned on the light emitting surface, and are used for reflecting light rays towards random directions.

Apparatus and method are provided for making the longitudinal temperature distribution of the bulbous end of a longitudinally oriented workpiece, such as a rail's head, generally uniform when the head has a non-uniform longitudinal temperature distribution. A combination of crown and skirt electric inductors is used to achieve the generally uniform temperature distribution by modulating the magnetic field intensity produced by current flow through one or more of the combination of crown and skirt inductors as required for the non-uniformly heated regions of the rail's head.

A substrate processing apparatus that includes a process tank having a pair of opposed sidewalls for storing a chemical liquid, and processing a plurality of substrates by the chemical liquid; a substrate holding mechanism including a holding part for holding the plurality of substrates, and a back part connected to the holding part and interposed between the substrates held by the holding part and one sidewall of the pair of opposed sidewalls when the substrate holding mechanism is loaded into the process tank. A heating device is disposed on the process tank for heating the stored chemical liquid. The heating device includes at least a first heater disposed on the one sidewall, and a second heater disposed on the other sidewall of the pair of opposed sidewalls. Energy outputs of the first heater and the second heater are independently controlled.

A tool is disclosed for separating a semiconductor die from a tape to which the die is affixed during the wafer dicing process. The tool includes a pick-up arm for positioning a vacuum tip over a semiconductor die to be removed. The vacuum tip includes a non-uniform array of vacuum holes to grip the semiconductor wafer.

An improved apparatus for correcting deflection in small diameter feed and retard rolls of an open width stabilizer so as to create a straight line nip with uniform pressure across the nip. The improved apparatus provides apparatus for adjusting deflection of the rolls to thereby maintain a desired size to a passageway between them so as to optimize compaction of a fabric web material. A wedge-like member is disposed between, and in moving relationship to, feed and retard roller bearings. The wedge-like member is asymmetrical, has feed and retard sides that engage the feed and retard roller bearings, respectively, and exerts reaction forces against each of the respective bearings. Improvement resides in the reaction forces causing the rolls the rolls to not deflect downwardly.

The device for producing a uniform or profiled fleece or a fiber flock mat includes a material dispensing device which produces a fleece and a transport device for the further transport of the fleece. The device also includes a measuring device to determine a transverse profile and a longitudinal profile of the fleece by measuring the mass per unit area of the fleece across its width, and a profile-changing device for supplying individualized fibers or fiber flocks to the fleece. A control unit controls the profile-changing device on the basis of the results of the measuring device in such a way that the profile-changing device supplies the individualized fibers or fiber flocks section by section in a targeted manner. Thus, depending on the purpose of the application, a uniform fleece or a fleece with a nonuniform transverse profile or longitudinal profile can be produced.

A method for preparing an object to be tested, having a given relative permittivity, intended to be illuminated by an incident electromagnetic wave. The method includes: providing a part including a cavity for housing the object and at least one extension element made from a material having a relative permittivity that is preferably equal to that of the object, the extension element at least partially delimiting the cavity and extending to either side of the cavity in a passage direction of the cavity, over a length at least equal, on either side of the cavity, to one third of the length of the cavity in the passage direction, and placing the object in the cavity, such that the object is in contact with the extension element in the passage direction.

The present disclosure provides one embodiment of an IC method. First pattern densities (PDs) of a plurality of templates of an IC design layout are received. Then a high PD outlier template and a low PD outlier template from the plurality of templates are identified. The high PD outlier template is split into multiple subsets of template and each subset of template carries a portion of PD of the high PD outlier template. A PD uniformity (PDU) optimization is performed to the low PD outlier template and multiple individual exposure processes are applied by using respective subset of templates.

Researchers from the Massachusetts Institute of Technology (MIT) have used fine-scale 3D bioprinting to grow cells that are highly uniform in shape and size, and potentially with certain functions.
