This study explored cellular receptors used by the GII.4 Norovirus Dijon strain by producing virus-like particles (VLPs) in insect cells and analyzing their binding characteristics to various integrin-expressing cells. Western blot confirmed the production of Dijon NoV-LPs. Flow cytometry analysis showed that NoV-LPs bound to integrin-expressing cells at levels 2-6 times higher than control cells, indicating integrins may serve as candidate receptors. This validates the use of NoV-LPs to study human Norovirus host protein interactions and aids in the design of attachment inhibitors.

1) Human bronchial smooth muscle cells (HBSMC) were exposed to quantum dots (QDs) to examine their cytotoxic and inflammatory responses under normal and asthmatic conditions.
2) QDs decreased cell viability of normal and asthmatic HBSMC in a dose- and time-dependent manner, with normal HBSMC being more sensitive.
3) Oxidative stress analysis found normal HBSMC maintained an antioxidant response to QDs, while asthmatic HBSMC showed a deficient response. Inflammatory mediator levels in both cell types increased with higher QD concentrations.

The document describes protocols for growth, pinning, and deletion assays to analyze the cytotoxic effects of three phenolic compounds - butylparaben, phenoxyphenol, and trifluoromethyl phenol - on yeast cells. In the growth assay, inhibitory concentration values were determined using optical density measurements. The pinning assay identified mutant yeast strains that were resistant or sensitive to phenol exposure. Preliminary results from the deletion assay suggest phenoxyphenol may cause DNA damage by inducing two-fold increases in deletion formation. However, results from the apoptosis assay were inconclusive. Further experiments are needed to better understand the DNA damage effects of the phenolic compounds.
Successful Strategies to Measure Residual Host Cell Proteins
Regulators require measuring residual host cell proteins (HCP) from early clinical development due to their potential to affect drug potency and safety. Commonly used "off-the-shelf" ELISA kits can measure HCP for many cell types during early development. However, later stages require validating kits for specific samples and developing product-specific HCP assays using antibodies that can detect relevant contaminating proteins. Advanced validation involves spiking known HCP amounts and assessing linearity, precision, and recovery near detection/quantitation limits.
The document describes several assays for measuring cell viability, cytotoxicity, and apoptosis. It provides details on assay mechanisms and recommended protocols for assays such as CellTiter-Glo, CellTiter 96 Aqueous, CellTiter-Blue, CellTiter-Fluor, CytoTox-Glo, CytoTox-One, Caspase-Glo 9, Caspase-Glo 8, and Caspase-Glo 3/7.

The results were inconclusive due to DNA degradation and possible human errors during experiments. As such, the study was unable to determine if the fruits contained GMO genes.
1. Kinetic molecular theory explains the states of matter based on the motion and interactions of particles. It assumes particles are in constant random motion and that temperature depends on the average kinetic energy of the particles.
2. Phase changes between solid, liquid, and gas are explained by KMT. As temperature increases, particles gain kinetic energy and overcome attractive forces, causing melting or boiling phase transitions.
3. Heating and cooling curves graphically represent phase changes over time as temperature changes. They show characteristic melting, boiling, freezing, and condensation points.
The document discusses the four states of matter - solid, liquid, gas, and plasma. It describes the characteristics of each state in terms of particle arrangement, energy, and distance between particles. Solids have a definite shape and volume, with particles in a tight, regular pattern. Liquids have a definite volume but no shape, with particles farther apart than solids but still not moving freely. Gases have no definite shape or volume, with particles much farther apart and moving freely at high speeds. Plasma is an ionized gas that conducts electricity and is affected by magnetic fields. It has an indefinite shape and volume like gases. The document provides examples of different phase changes between states of matter and natural occurrences of

The document discusses the five states of matter - solid, liquid, gas, plasma and Bose-Einstein condensate - and describes their characteristics at the molecular level. It also explains several concepts relating to changes between the different states of matter, such as phase changes, evaporation, boiling, and freezing. Kinetic theory is introduced as describing matter as made of particles in constant motion, and factors that influence processes like evaporation, boiling, freezing and pressure are defined.
There are five states of matter: solids, liquids, gases, plasmas, and Bose-Einstein condensates. Solids have tightly packed particles that vibrate in a fixed position and definite shape and volume. Liquids also have tightly packed particles, but they can slide over one another and have indefinite shape but definite volume. Gases have particles far apart that move freely with indefinite shape and volume. Plasmas are ionized gases that conduct electricity and are affected by magnetic fields. Bose-Einstein condensates occur at temperatures near absolute zero where atoms can no longer be distinguished as individuals and must act identically.
The document discusses the four phases of matter: solids, liquids, gases, and plasma. It describes the properties of each phase, including how tightly or loosely packed the particles are and whether they have a definite volume and shape.

Golden Gate cloning and Gateway cloning are molecular cloning techniques that allow efficient transfer of DNA fragments between vectors. Golden Gate cloning uses type IIS restriction enzymes to generate unique overhangs on DNA fragments, enabling their simultaneous assembly. Gateway cloning uses site-specific recombination to transfer DNA fragments between vectors in a scarless manner. TA cloning exploits the terminal transferase activity of Taq polymerase to directly clone PCR products into T-vectors. These techniques streamline cloning workflows compared to traditional restriction enzyme-based cloning.

Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

Freshworks Rethinks NoSQL for Rapid Scaling & Cost-EfficiencyScyllaDB
Freshworks creates AI-boosted business software that helps employees work more efficiently and effectively. Managing data across multiple RDBMS and NoSQL databases was already a challenge at their current scale. To prepare for 10X growth, they knew it was time to rethink their database strategy. Learn how they architected a solution that would simplify scaling while keeping costs under control.
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

QA or the Highway - Component Testing: Bridging the gap between frontend appl...zjhamm304
These are the slides for the presentation, "Component Testing: Bridging the gap between frontend applications" that was presented at QA or the Highway 2024 in Columbus, OH by Zachary Hamm.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
