This document discusses quantum computation and its advantages over classical computation. Quantum computation uses quantum bits (qubits) that can exist in superpositions of states rather than just 1s and 0s. This allows quantum processors to perform multiple computations simultaneously. While challenging to implement physically, quantum algorithms like Shor's algorithm could solve certain problems like integer factorization vastly faster than any classical computer. Nanotechnology is needed to build qubits that can maintain coherent superpositions, potentially enabling the construction of a functional quantum computer.

ChemFET fabrication, device physics and sensing mechanismRichard Yang
1. Organic thin-film field-effect transistors (OTFTs) were fabricated and tested for chemical sensing applications. Pulsed gate operation was found to significantly reduce device baseline drift compared to static operation.
2. Charge transport in the organic semiconductor films occurs via multiple trapping and release of charge carriers. Variable temperature measurements showed thermally activated transport, with the activation energy dependent on gate voltage.
3. Exposure to chemical vapors causes a change in device characteristics due to the interaction of adsorbed analyte molecules with the doped organic semiconductor surface layer. This modifies both the surface doping level and trap energies.
Demonstrating Quantum Speed-Up with a Two-Transmon Quantum Processor Ph.D. d...Andreas Dewes
1. Andreas Dewes demonstrated quantum speed-up using a two-transmon quantum processor.
2. The processor realized a universal set of gates including single-qubit rotations and a two-qubit entangling gate through tunable coupling between transmon qubits.
3. Quantum algorithms like Grover's search were implemented on the processor, exhibiting quantum speed-up over classical algorithms for the same tasks.
Quantum computing uses quantum mechanics phenomena like superposition and entanglement to perform operations on quantum bits (qubits) and solve certain problems much faster than classical computers. One such problem is integer factorization, for which Peter Shor devised an algorithm in 1994 that a quantum computer could solve much more efficiently than classical computers. While quantum computing is still in development, it has the potential to break popular encryption systems like RSA and simulate quantum systems. Practical implementations of quantum computing include ion traps, NMR, optical photons, and solid-state approaches. Quantum computing could enable applications in encryption-breaking, simulation, and cryptography, among other areas.
The document presents a two-level approach for solving stochastic planning problems in operating rooms. At the first level, a deterministic model is used to allocate block times to specialties. At the second level, a stochastic model incorporates random durations to determine if solutions are feasible with high probability. Safety slacks are calculated for blocks likely to exceed durations and fed back into the deterministic model in an iterative process until a robust solution is found. Monte Carlo simulation and the Fenton-Wilkinson approximation are also discussed to model lognormal durations. The approach is applied preliminarily to an operating room case study.

1. The document discusses synchronization of single-phase power converters to the electric grid. Grid synchronization is important as more renewable energy sources connect directly to local distribution grids.
2. There are two main grid synchronization methods - frequency-domain detection and time-domain detection. Phase-locked loops (PLLs) are commonly used for time-domain detection.
3. The basic structure of a PLL contains a phase detector, loop filter, and voltage-controlled oscillator. An in-quadrature signal is needed at the phase detector input to eliminate double-frequency oscillations in the phase error signal.

Design and implementation of qpsk modulator using digital subcarrierGongadi Nagaraju
The digitally implemented QPSK modulator is developed for satellite communication for future satellite missions. As we know that for space application power and bandwidth are most important parameters.The size of PCB and component count are also important parameters. To reduce these all parameters we design new approach. The new approach also minimizes the component count and hence reduces the PCB size. In this modulator summation, orthogonal sub-carrier generation and mixing of subcarrier with data are all digitally implemented inside the FPGA

This document discusses the Axiom of Choice (AC), a foundational principle in set theory that states that for any set of nonempty sets, there exists a function that chooses one element from each set. The document provides examples to illustrate AC with finite and infinite sets. It explains that while AC seems intuitive for finite sets, it leads to counterintuitive conclusions for infinite sets. The document also discusses the relationship between AC and Zermelo-Fraenkel set theory (ZF), noting that ZF does not prove or disprove AC, so its inclusion in ZF is a matter of mathematical preference.

Can christian schools continue to teach only about traditional marriage2idseminar
An approach to the big general issue whether faith schools should be allowed to teach based on their fundamental beliefs and discriminate amongst teachers and students because of their faith.
1. The document discusses three potential traits that define humanity: understanding and language, freedom and self-responsibility, and unlimited desire.
2. It argues that unlimited desire, which drives humans to constantly search for meaning, happiness, and fulfillment through questions, choices, love and communion, may be the most fundamental human trait.
3. This trait of unlimited desire can justify fundamental personal rights like the right to life, freedom, and due process, which in turn other rights are derived from, in order to ensure humans can fulfill their desires. However, recognizing another's humanity ultimately requires choice and acknowledgement of their desires too.

- the effects of these causes, however, are observable by physical and scientific means.
Physics is not complete.
The presentation has two parts. In the first one, we review a series of studies that compare the efficacy of learning with "digital teachers" as opposed to learning with normal teachers. In the second part, we make several considerations from different points of view that may be helpful to answer the question.
1) The document discusses future contingencies and the multiverse perspective from Antoine Suarez combining two philosophical views.
2) It describes Ernst Specker's work on quantum contextuality and includes photos of Specker with his son and colleague Simon Kochen.
3) Suarez identifies Hugh Everett's many worlds theory with thoughts in the "mind of God", finding a way to incorporate a deity into the picture according to a quote in Nature.

Achilles, the Tortoise and Quantum Mechanics
Alfred Driessen
prof. emer. University of Twente
In several places of his Physica Aristotle analyzes the famous antimony of Zeno about the competition between Achilles and the Tortoise. He emphasizes that any movement, or more general any change, is actually a continuum, i.e. an unity. It depends on the specific movement or change whether this continuum is potentially divisible in parts. In fact, there could be certain minima of the division. In line with this approach, Quantum Mechanics states that there are minima or quanta of movement (or change), with other words, there are no gradual changes in the world of micro- and nano-structures. This behavior is completely unexpected when starting with the mechanistic approach of classical physics.
Taking another finding of Aristotle, the four aspects of causality including final cause, one gets another ingredient of Quantum Mechanics. Movements and changes are not only influenced by the initial state -describing the present situation- but also by the final state which takes account of the future situation. As an example one may mention Fermi’s golden rule, where the initial and final state symmetrically determine the transition probability.
Bringing these two philosophical concepts of Aristotle together namely quanta of movement and final cause, a new light is shed on fundamental issues in Quantum Mechanics. One may mention the experimental evidence for contextuality, which is considered one of the weird phenomena in Quantum Mechanics. As illustration, some of the examples of experiments with optical microresonators are given.
This talk has been presented at the 20th International Interdisciplinary Seminar "Can Science and Technology Shape a New Humanity", Netherhall House, London, 5-1-2018
This document discusses transhumanism and postgenderism. It summarizes views from gender studies that gender is more a social construct than biological essentialism. It explores how technologies may enable a postgender society without the gender binary, including artificial wombs, drugs controlling sexual behaviors and bonding, genetic engineering to change sex, and robots for sexual needs. However, the document concludes that pursuing postgenderism through technologies may dehumanize humanity and lose the richness of gender complementarity.
This presentation lists some brain-computer interface technologies that exist today and that could be attainable in future. At the end, philosophical comments about this kind of technology and transhumanism are purposed, in order to reveal the key difference between a humain brain and artificial intelligence.
The document discusses transhumanism and compares human and artificial intelligence. It covers current technologies like mini antennas and potential future technologies like telepathy and neuroreality. It then compares how humans and artificial systems learn, with humans able to reach an understanding of essence while artificial intelligence relies on computational power. The document concludes that hard transhumanism, with robots becoming the dominant lifeform, clashes with philosophical views, while soft transhumanism involves more integration between humans and robots but maintains humans as the primary agents.
1. The document discusses the differences between sequential processing in nature compared to scientific computation. Protein folding occurs sequentially and efficiently in nature, while computation relies on approximation and linearization.
2. Artificial neural networks provide some similarities to natural processes by using weighted connections between nodes, but training requires vast resources compared to natural systems.
3. Quantum computing may provide solutions in a way analogous to how nature appears to "know" the right protein folding solution, but this ability is not well understood.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

3. Quantum technologies
• Leave philosophy to philosophers, assume that QM works
(which it does) and see if you can do anything useful with it
• Quantum 1.0 revolution (20th century): transistors, lasers,
integrated circuits, magnetic resonance, …
• Quantum 2.0 revolution (21st century): entanglement,
coherence, superposition …

One bit gates
NOT (inverter), (Identity)
Two bit gates
• AND, OR, NAND, NOR, XOR, XNOR
• NAND and NOR are universal: any
Boolean function can be implemented
using combinations of them
