Future Proof
Future-proofing is the process of anticipating the future and developing methods of minimizing the effects of shocks and stresses of future events. Future-proofing is used in industries such as electronics, medical industry, industrial design, and more recently, in design for climate change. The principles of future-proofing are extracted from other industries and codified as a system for approaching an intervention in an historic building.

Colon Cancer Diagnosis
Researchers presents a comprehensive survey on the diagnosis of colon cancer. This covers many aspects related to colon cancer, such as its symptoms and grades as well as the available imaging modalities (particularly, histopathology images used for analysis) in addition to common diagnosis systems. Furthermore, the most widely used datasets and performance evaluation metrics are discussed. Researchers provide a comprehensive review of the current studies on colon cancer, classified into deep-learning (DL) and machine-learning (ML) techniques, and researchers identify their main strengths and limitations. These techniques provide extensive support for identifying the early stages of cancer that lead to early treatment of the disease and produce a lower mortality rate compared with the rate produced after symptoms develop. In addition, these methods can help to prevent colorectal cancer from progressing through the removal of pre-malignant polyps, which can be achieved using screening tests to make the disease easier to diagnose. Finally, the existing challenges and future research directions that open the way for future work in this field are presented.

Sustainable Food Production
Fault diagnosis and prognosis methods are the most useful tools for risk and reliability analysis in food processing systems. Proactive diagnosis techniques such as failure mode and effect analysis (FMEA) are important for detecting all probable failures and facilitating the risk analysis process. However, significant uncertainties exist in the classical-FMEA when it comes to ranking the risk priority numbers (RPNs) of failure modes. Such uncertainties may have an impact on the food sector’s operational safety and maintenance decisions.

IBM CP-40
CP-40 was a research precursor to CP-67, which in turn was part of IBM's then-revolutionary CP[-67]/CMS – a virtual machine/virtual memory time-sharing operating system for the IBM System/360 Model 67, and the parent of IBM's VM family. CP-40 ran multiple instances of client operating systems – particularly CMS, the Cambridge Monitor System, built as part of the same effort. Like CP-67, CP-40 and the first version of CMS were developed by IBM's Cambridge Scientific Center (CSC) staff, working closely with MIT researchers at Project MAC and Lincoln Laboratory. CP-40/CMS production use began in January 1967. CP-40 ran on a unique, specially modified IBM System/360 Model 40.

IBM Spectrum Control
IBM Spectrum Control formerly known as Tivoli Storage Productivity Center (TPC) is a Storage Resource Management (SRM) software offering that provides a centralized point of control for managing large-scale, complex heterogeneous storage environments. IBM Tivoli Storage Productivity Center V5.2.x (5608-PC1) was renamed in V5.2.8 to IBM Spectrum Control Standard Edition V5.2.x (5608-PC1).

Sixth Term Examination Paper
Sixth Term Examination Papers in Mathematics, often referred to as STEP, are university admissions tests for undergraduate Mathematics courses developed by the University of Cambridge. STEP papers are typically taken post-interview, as part of a conditional offer of an undergraduate place. There are also a number of candidates who sit STEP papers as a challenge. The papers are designed to test ability to answer questions similar in style to undergraduate Mathematics. There are two official users of STEP Mathematics: the University of Cambridge and the University of Warwick. Candidates applying to study Mathematics or Computer Science with Mathematics at the University of Cambridge are required to take STEP papers as part of the terms of their conditional offer. In addition, other courses at Cambridge University with a large mathematics component, such as engineering occasionally require STEP. Candidates applying to study Mathematics or closely-related subjects at the University of Warwick can take step as part of their offer. A typical STEP offer for a candidate applying to read Mathematics at the University of Cambridge would be at least a grade 1 in both STEP2 and STEP 3. From 2019 some colleges may (depending on the individual applicant's circumstances) require a grade 1 in either STEP 1 or 2 , (or in both). Candidates applying to the University of Warwick to read Mathematics, or closely related subjects, can use a grade 1 from any STEP paper as part of their offer.

Non-Malleable Codes
The notion of non-malleable codes was introduced in 2010 by Dziembowski, Pietrzak, and Wichs, for relaxing the notion of error-correction and error-detection. Informally, a code is non-malleable if the message contained in a modified code-word is either the original message, or a completely unrelated value. Non-malleable codes provide a useful and meaningful security guarantee in situations where traditional error-correction and error-detection is impossible; for example, when the attacker can completely overwrite the encoded message. Although such codes do not exist if the family of "tampering functions" F is completely unrestricted, they are known to exist for many broad tampering families F.

Electrochemical RAM
Electrochemical Random-Access Memory (ECRAM) is a type of non-volatile memory (NVM) with multiple levels per cell (MLC) designed for deep learning analog acceleration. An ECRAM cell is a three-terminal device composed of a conductive channel, an insulating electrolyte, an ionic reservoir, and metal contacts. The resistance of the channel is modulated by ionic exchange at the interface between the channel and the electrolyte upon application of an electric field. The charge-transfer process allows both for state retention in the absence of applied power, and for programming of multiple distinct levels, both differentiating ECRAM operation from that of a field-effect transistor (FET). The write operation is deterministic and can result in symmetrical potentiation and depression, making ECRAM arrays attractive for acting as artificial synaptic weights in physical implementations of artificial neural networks (ANN). The technological challenges include open circuit potential (OCP) and semiconductor foundry compatibility associated with energy materials. Universities, government laboratories, and corporate research teams have contributed to the development of ECRAM for analog computing. Notably, Sandia National Laboratories designed a lithium-based cell inspired by solid-state battery materials, Stanford University built an organic proton-based cell, and International Business Machines (IBM) demonstrated in-memory selector-free parallel programming for a logistic regression task in an array of metal-oxide ECRAM designed for insertion in the back end of line (BEOL). In 2022, researchers at Massachusetts Institute of Technology built an inorganic, CMOS-compatible protonic technology that achieved near-ideal modulation characteristics using nanosecond fast pulses

MediaMax CD-3
MediaMax CD-3 is a software package created by SunnComm which was sold as a form of copy protection for compact discs. It was used by the record label RCA Records/BMG, and targets both Microsoft Windows and Mac OS X. Elected officials and computer security experts regard the software as a form of malware since its purpose is to intercept and inhibit normal computer operation without the user's authorization. MediaMax received media attention in late 2005 in fallout from the Sony XCP copy protection scandal. MediaMax is a second-generation system meant to address the problems of earlier copy-preventing schemes, where many types of playback devices had difficulty reading discs in normal use. MediaMax was first used on Anthony Hamilton's Comin' From Where I'm From in the United States ; the first US No. 1 CD to use it was Velvet Revolver's Contraband. (The European release of the Velvet Revolver album used Macrovision CDS-200 and the Japan ese is without copy protection.)

C W Henderson founded the company in 1984 and its first publication was AIDS Weekly. In the early 2000s, the firm added the imprint, VerticalNews to publish newsweeklies in non-health fields. Now based in Atlanta, Georgia, the company reports through its daily news service and publishes reference books through its partner, ScholarlyEditions. NewsRx launched its BUTTER platform in 2015, which is a knowledge discovery engine that delivers its content to academics, researchers, and professionals.
