Veterans, PTSD, and Equine-Assisted Psychotherapy: Perspectives of Licensed Mental Health Therapists
Authors: Hoermann Valerie , Burger Michael L
Published: February 2023

Veterans returning home after deployment and active military personnel have been members of a highly vulnerable population for whom trauma, suicide, domestic issues, substance abuse, crime, and homelessness have been complicating factors. Equine-assisted psychotherapy (EAP) has gained in popularity as a treatment for post-traumatic stress disorder (PTSD) and other mental illnesses Veterans experience. It has drawn attention from federal agencies, but the literature pertaining to the best and most effective techniques and practices is unclear or nonexistent. We conducted this study to (a) analyze licensed equine-assisted mental health therapists’ (LMHT) observations regarding the relative efficacy of EAP in mitigating or eliminating PTSD symptoms in Veterans, and (b) help LMHTs adopt and implement a set of best practices with respect to EAP for U.S. Veterans who suffer from PTSD. We hoped the answers to both of those inquiries would improve understanding and practices associated with using EAP as a treatment for PTSD. The 31 LMHTs who participated reported that EAP worked best for PTSD (as a stand-alone therapy) when compared to 10 other mental health disorders. They did not think EAP worked as well for clients whose diagnosis included schizophrenia. Typically, sessions consisted of one client (although the size of the treatment group did not impact EAP’s effectiveness). The sessions typically ran from one to two hours. We recommend the establishment of a clearing house that provides information on the relative effectiveness of different practices, and that other researchers examine the long-term effects of preferred treatments on Veterans.
Peace, Security, or the Economy? Israeli Narratives About the Abraham Accords
Authors: Hallward Maia Carter
Published: February 2023

In 2020 several Arab states announced U.S.-brokered full normalization agreements with Israel, absent any explicit compromises on Israel’s side vis-à-vis the Palestinians, a significant shift from traditionally held positions. While several of these states already had informal security, intelligence, and trade relations with Israel and, except for Sudan, were never at war with Israel, these agreements represented a significant shift in historical Arab-Israeli relations and thus required discursive justification to a range of audiences, including the Arab and Israeli publics. This article looks specifically at how the Abraham Accords were framed in the Israeli press and takes an initial look at the extent to which the Accords have impacted Israel’s economic and security situation.
The Abraham Accords - Israel and the Middle East - What Next?
Authors: Zisser Eyal
Published: February 2023

The signing of the Abraham Accords in September 2020 was a turning point in Israel's standing in the Middle East. The accords created a positive atmosphere that helped promote regional cooperation in security and the economy. This positive change does not, however, provide an answer to some of the fundamental challenges that Israel is facing, which cast their shadows on the entire region, such as the Iranian threat - Tehran's regional ambitions and its efforts to gain nuclear capabilities; but first and foremost, the Israeli-Palestinian conflict, which is getting further and further away from a solution, and may flare up and damage regional stability and hinder the progress in Israeli-Arab relations, which was achieved following the signing of the Abraham accords.

This paper discusses the process and methodological aspects of X-ray fluorescence online monitoring of ore silver grade at the underground mines and open pits operated by Kazakhmys Corporation LLC. The analysis was complicated by the requirement to: a) ensure reliable silver grade determination of the ore, starting at 1+ ppm; b) sample mine faces in vertical sections to a height of up to 7 m. For geophysical online monitoring of the ore material in the walls of mine workings and in the broken rock mass, a portable energy-dispersive X-ray fluorescence spectrometer RPP-12T (Aspap Geo LLC, Alma-Ata) was developed, assembled, and comprehensively tested. The results of investigations carried out using the RPP-12T spectrometer are discussed. The data collected during the investigations made it possible to implement online ore silver grade monitoring in the underground mines and open pits operated by Kazakhmys Corporation LLC.

The study aimed to determine the optimal conditions for adsorption and elution of iron from acid mine drainage by ion-exchange resin LEWATIT MonoPlus TP 207 under a batch regime of operation. Langmuir's sorption equation was employed to analyse the equilibrium data from the experiments. The data fitting demonstrated that the process obeyed pseudo-second-order kinetics with a linear regression coefficient (R2) of 0.9999. Because of the higher demand for hydrochloric solution (100 g/ L) for the ferric iron elution, we studied the effect of the preliminary stage of galvanic elution of Fe(III) to Fe(II) in the presence of H2. In that way, a slightly acidic solution (30 g/ L) was sufficient to desorb more than 95 % of iron from ion exchange resin LEWATIT MonoPlus TP 207 at a temperature of 70 °C.

Studies of foreign experience in the extraction of magmatic rocks for decorative and cladding purposes show a continuing trend for the use of high-speed explosives in the primary separation of the rock block from the massif. The belief that this is the cheapest way for primary extraction against the background of the prices for cutting of hard and highly abrasive rocks with diamond-rope, chain- and disk-stone cutters, makes quarry owners to put up with the losses from unwanted cracking of high-quality material. The authors undertook a series of experiments on samples of magma rock with hardness f = 16 according to Protodyakonov. The advantages and disadvantages of an alternative non-explosive technology for stone splitting with bulk-expanding mixtures were analysed. The results were compared with those using detonating cord charges to detach rock blocks with the same characteristics.

The waste electrical and electronic equipment (WEEE) is an important secondary source for renewable extraction of valuable metals and raw materials. The mineral biotechnologies are promising alternative to the current industrial chemical technologies for waste treatment, which are often accompanied with negative environmental impact. Here we report a systematic biotechnological strategy for recycling, recovering and extraction of metals from WEEE as biogenic formed nanoparticles. The process is based on two general steps – bioleaching (through autotrophic/heterotrophic bacteria), and extraction from the effluent as biosynthesised nanoscale materials. The obtained analytical data revealed that copper was bioleached in the form of nanoparticles, the efficiency being more than 90 %, which was the highest achieved value in comparison with the other metals. The recovered content of gold was less than 50 %, but the efforts for improvement of microbial leaching efficiency of Au are still in progress. The reported eco-friendly biotechnological approach enables proper implementation of new resource recovery-oriented recycling strategies with reduced risk of negative impact on nature.

Authors:   Development International Inc., 31 Oakland Av., Pontiac, MI48324 USA, Brodt Alexander
Published: February 2023

A method for direct liquefaction of coal is presented. After separating the coal from waste rock gravitationally in an aqueous salt solution, drying and grinding, the purified separated coal is mixed with a paste-forming reagent. The paste is ground until a colloidal particle size and hydrogenated for 2 hours at temperature of 405°C and 11 MPa hydrogen pressure. Artificial oil was obtained with over 95 % yield with respect to the initial amount of purified coal when the contact of excavated coal with air was avoided. Based on findings, a technology is proposed for underground coal liquefaction with significantly reduced energy consumption of the process, removed environmental hazards and higher efficiency with respect to existing technologies.
On using excess Gibbs energy as an indicator of hydrophobicity in the flotation process

It has been shown that the partial molar excess Gibbs energy (G̅ex) can be used as an indicator of hydrophobicity and hence contributes to explaining the behaviour of collectors in the recovery of minerals by flotation. This is because hydrophobicity of a mineral particle on which a collector is adsorbed is related to the fact that the alkyl chain associated with the collector behaves in the same way as any hydrocarbon would in a non-ideal mixture with water. Such mixtures are quantified thermodynamically by determining the activity coefficient of the hydrocarbon moiety of the collector and hence its G̅ex in the mixture. The present paper is aimed at extending the above concepts in two different ways. Firstly, an investigation is made of the relationship between G̅ex and contact angle and/or recovery for systems such as ionic liquids and aminothiophenols. Secondly, on the basis of the observation that increases in G̅ex are indicative of increases in the hydrophobicity of the mineral particle-collector aggregate, a study was undertaken to examine, respectively, the effects of the presence of electrolytes or alcohols in the system, of pH and changing concentrations of the collector, on G̅ex of the collector alkyl group and hence its hydrophobicity. In the first instance, the relationship between G̅ex and contact angle and recovery is sustained. With respect to the latter, the absence of any correlation between G̅ex and recoveries supported the proposition that the major effect of electrolytes and added alcohols is rather on particle – bubble attachment. Similarly, it is also indicated that since the change in G̅ex is minimal when collector concentration or pulp temperature is increased these changes do not significantly affect the hydrophobicity of the collector-mineral particle and hence also the recovery in a microflotation.
Industrial symbiosis in raw material sector as an overarching solution in circular economy
Authors:   University of Mining and Geology “St. Ivan Rilski”, Petrova Vessela
Published: February 2023

Circular economy is a key instrument for reducing climate change and transition to green economy. The industrial symbiosis is a circular business model – a concept, discussed as a platform for exchange of materials among business companies in order to achieve sustainability and reduce waste. “Shared use” of wastes as raw-materials results in multiple benefits – economic (reduction of cost to produce raw materials), environmental (reduction of generated waste, reduction of CO2 emissions, opportunities for applying the green policies), as well as social benefits (creating “green” job positons, support to local communities). A discussion is presented in the paper on industrial symbiosis as an important opportunity for developing a circular economy by the established business model. A survey among thirteen (13) companies from the mineral raw-material sector has been performed and it has proved that companies are aware of the concept, even more – to a certain extent, companies perform the concept in their day-to-day activities. The paper has marked the need of actually mapped networks, which will model a sustainable industrial symbiosis.

Sustainable land application in post-mining areas is an essential ecological issue, connected with disturbed areas, pollution of heavy metals, etc. The current research studies opportunities for phytoremediation of lands disturbed by copper mining. Environmental state and soil conditions are examined. Analyses show that soils are weakly acidic, with a low concentration of total nitrogen, a very high concentration of K2O and P2O5, and arsenic above permissible values. The research determines phytostabilisation as a more reliable method for phytoremediation of disturbed lands in this case. The appropriate species for phytostabilisation have been studied. Based on the analysis of data, climate, and soil conditions, it is determined that tree species of four genera show the best ability for phytoremediation in this type of terrain: Populus, Betula, Acer, Salix. Afforestation schemes and possible methods for biomass treatment are proposed.

Published: February 2023

The AZUR apparatus is intended to control the insulating resistance in mine networks with an isolated star centre. The indication of the measured insulating resistance is realised by a pointer meter with a reversed nonlinear scale, which makes it difficult to read. The methodology for the development of an analogue converter is considered here, which linearises the non-linear characteristic current-resistance and, together with a light indicator, the device allows for more accurate and easy reading. An analysis of the error and the measurement range is made.

Abstract Background: Little is known about a burden of acute illness and injury that would be addressed with improved prehospital care in Ethiopia. This study aimed to quantify the burden of emergency conditions that potentially benefited from implementation of prehospital care service in Jimma city, Ethiopia.Method: This study is secondary analysis of dataset originally created to characterize the burden of emergency conditions presenting to public hospitals in Jimma city, from 2014 to 2017. We included of 19,885 eligible cases out of 39,537 emergency cases visited to hospitals, and rated for amenability to prehospital care using previous definitions devised for priority emergency conditions in Low-and Middle-Income-Countries. Demographic health report for the same period was also obtained from Jimma health office, and used to quantify the population-normalized rates of demand for prehospital care in the study area. Descriptive analysis was used to summarize demographic data, causes of visit, and need for prehospital care. Odd ratios were calculated to assess the need for prehospital care across major clusters of diseases, statistically significance was considered at a P-value<0.05. Results: We identified 51.1% (n=10163) of all emergency visits to local hospitals with acute conditions would have benefitted from receiving prehospital care. Maternal emergencies (22.2%, n=2255), lower respiratory infections (20.8%, n=2116) and trauma (27.8%, n=5527) were leading conditions in need of prehospital care. On average, there were 3388 acute events per year, or 1 acute event per every 56 individuals in the population, which could have potentially from prehospital care. Conclusion: This study identified a significant proportion of emergency conditions could have experienced improved health outcomes had prehospital services been available and rendered in Jimma city. These results provide additional justification for development of formalized prehospital services in Jimma, as well as the need for continued investigation of the health benefits of prehospital care in Ethiopia.

Electrocardiogram (ECG) is instrumental in identifying acute myocardial infarction (AMI). ST-segment elevation in a region of specific coronary vessels in an acute coronary syndrome (ACS) setting is the hallmark of AMI. Reciprocal ST depression and T wave inversion (TWI) are well-recognized changes that could accompany ST segment elevations. Reciprocal changes may represent the only early manifestation of AMI and may be present in specific leads such as lead aVL as early and sensitive markers of AMI. Abnormalities in the ST segment and T wave can result from non-ACS causes, but early recognition and appropriate intervention are paramount for patients with ACS. We report a case of a 55-year-old male with acute IWMI with early reciprocal and dynamic ECG changes with a literature review.

Sampai saat ini permasalahan sertifikat tanah ganda atau yang lebih dikenal dengan tanah sengketa masih tetap ada, dan merupakan permasalahan lama yang belum terselesaikan. Terjadinya sertifikat tanah ganda antara lain akibat data base pada Badan Pertanahan Nasional tidak valid, sehingga penyelesaian pembuatan sertifikat yang kedua dan seterusnya bisa dikatakan tidak selektif. Di pihak masyarakat masalah pertanahan khususnya masalah sertifikat tanah ganda dikabupaten kolaka belum sepenuhnya disadari, dan baru sadar setelah ada orang lain yang juga mempunyai sertifikat tanah atas tanah yang ia miliki. Karena ketidaktahuan masyarakat terhadap sertifikat tanah ganda, maka ia tidak bisa mengadakan upaya pencegahan. Tujuan dari penulisan ini untuk berusaha memberikan informasi, penyebab terjadinya sertifikat ganda dan bagaimana mengurangi/mencegah akan terjadinya sertifikat ganda atas tanah. Sebenarnya penyebab terjadinya sertefikat ganda di karenakan pada tahun 2017 peta digital masih manual sehinggah data base tentang pembuatan sertefikat tidak valid dan untuk pencegahannya, harus dilakukan secara serentak di semua lini yang ada kaitannya dengan data pertanahan. Pihak pemerintah sebagai penanggung jawab terhadap terjadinya sertifikat ganda harus mempunyai keberanian dan ketegasan dalam menegakkan hukum pertanahan. Disamping itu, pemerintah harus bisa memberikan informasi secara rutin tentang sertifikat agar masyarakat tahu semua kemungkinan yang menyebabkan terjadinya sertifikat ganda dan pemerintah juga harus mampu memfasilitasi peta digital setiap kantor pertanahan

Factors Influencing Driving Time in Public Transport – A Multiple Regression Analysis
Authors: Bajčetić Stanko , Živanović Predrag , Tica Slaven , Milovanović Branko , Nađ Andrea
Published: February 2023

Deviations in driving time (DT), or significant variations, occur frequently on urban public transport (PT) lines, except in subsystems with separate routes. DT variability is the main reason for disturbances in operation, leading to unstable and unreliable transport service. Moreover, it also causes variability in total user travel time, which is one of the main parameters of transport service quality. Identifying and quantifying factors that influence PT vehicle DT characteristics is significant for designing advanced prediction and  passenger information systems and prioritising investments to reduce bus travel time and improve the scheduling process, and thus the level of transport service quality. An analysis of the elements of the route and other static elements of the line that influence DT was carried out in this paper. A model for determining and quantifying influential factors and methodologies for collecting all necessary data was created. The multiple regression model, developed as a result of the conducted multivariate statistical analysis using the specialised SPSS software, was applied to the selected representative set of lines in a real urban PT system. The created regression model explains between 18.2% and 97.4% of the variance of average, minimum and maximum DT and its deviation in the peak and off-peak periods.
Asymmetric Behaviour and Traffic Flow Characteristics of Expressway Merging Area in China
Authors: Zhang Weihua , Wei Siping , Wang Changsheng , Qiu Meng
Published: February 2023

Drivers show different characteristics in traffic oscillations. These differences reflect the driver’s driving style, which is an important part of traffic uncertainty. This paper deeply explores the driving characteristics in asymmetric driving behaviour and its influence on traffic flow characteristics. The aim is to improve the understanding of safe driving. Continuous vehicle trajectories under various traffic flow conditions in an expressway merging area are obtained by aerial photography. Image processing technology is used to extract the basic parameters of traffic flow and vehicle operating characteristic data. Based on the measured data, the driver’s response mode is subdivided into multiple sub-modes. On the basis of this study, the types and distribution of traffic hysteresis and the impact of asymmetric behaviour on merging area capacity are further revealed. The results show that the response coefficient will increase for 58.72 % drivers during the process of experiencing oscillation disturbance to rebalance. The traffic hysteresis caused by driver’s asymmetric following behaviour in an expressway merging area is generally positive. This reduces the bottleneck outflow rate of the merging area by about 7 % on average. This study has important practical significance in analysing the formation mechanism of traffic congestion and adopting effective protective measures.
Coexistence of quantum spin and valley hall effect in two-dimensional dielectric photonic crystals

The location and transmission of light is the core of modern photonic integrated device, and the proposal of topological photonics provides a new way of implementing optical manipulation. Topological photonic structures based on the quantum spin hall effect or quantum valley hall effect have the properties of immunity to defects and suppress backscattering, so they play a key role in designing novel low-loss photonic devices. In this work, we design a two-dimensional dielectric photonic crystal with time-reversal symmetry to achieve the coexistence of the quantum spin hall effect and the quantum valley hall effect in a photonic crystal. The design can be likened to an electronic system in which two pairs of Kramers simplex pairs are constructed to achieve a quadruple simplex pair in a photonic crystal. First, based on the method of shrinking and expanding the silicon pillars arranged in the honeycomb structure, the quadruple degeneracy point at the Γ point of the first Brillouin zone is opened, and the corresponding topologically trivial or non-trivial photonic band gap is formed,thereby realizing quantum spin hall effect. The expanded honeycomb lattice evolves into a Kagome structure, and then positive and negative perturbations are added to the Kagome lattice, breaking the spatial inversion symmetry of the Photonic crystal. When mirror symmetry is broken, different chiral photonic crystals can be created,leading the degeneracy point of the non-equivalent valleys K and K' in the Brillouin zone to be opened and a complete band gap to appear, thus realizing the Quantum valley hall effect. In the common band gap, topologically protected edge states are induced by nontrivial valley Chern number at the interface between two photonic crystals with opposite chirality. The numerical calculations show that unidirectional transport and bending-immune topological boundary states can be realized at the interface composed of topologically trivial (non-trivial) and positively (negatively) perturbed photonic crystals. Finally, a four-channel system based on the coexistence of the two effects is designed, The system is a novel electromagnetic wave router that can be selectively controlled by pseudospin degree of freedom or valley degree of freedom. This system provides a potential method for realizing the optical encoding and robust signal transmission, thereby providing greater flexibility for manipulating electromagnetic waves.
A method of measuring complex ermittivity of nonmagnetic materials and selecting its initial value based on iterative inversion

Complex permittivity is an important parameter to reflect the macroscopic electromagnetic properties of material. The selection, design, and application of related materials and devices in the electromagnetic field must be based on the electromagnetic parameters of materials in the working frequency band. The numerical iterative method is an important method to inverse and calculate the complex permittivity of material. But there always exists a difficult problem that the initial value of iteration is difficult to give accurately. Based on the relationship between the complex permittivity and the reflectivity of absorbing material, an initial value selecting method for iteration to invert permittivity of absorbing material is proposed in this work. For absorbing materials with arbitrary thickness at a certain frequency, the complex permittivity must be near the complex permittivity of perfect matching layer. Therefore, the permittivity of perfect matching layer can be used as the initial value of the iterative algorithm. On this basis, a method of calculating the complex permittivity of monolayer absorbing material by using the reflection parameter is constructed. The experimental results show that the complex permittivity of lossy material can be calculated more accurately at the frequency with absorbing performance. However a great error can be caused at the frequency where the reflectivity is close to zero. Based on the iterative solution of the complex permittivity of single-layer absorbing material, a new method of measuring the complex permittivity of material is constructed by combining multi-layer absorbing materials to enhance full-band reflectivity. Given the electromagnetic parameters of other layer materials , the permittivity of absorbing materials and low-loss materials can be obtained accurately.

To meet the demands for various applications in optical filtering and microwave signal processing, integrated silicon photonic filters are required to be multifunctional, reconfigurable and tunable. In this work, an integrated multi-functional optical filter is proposed, which is designed based on a tunable Sagnac loop reflector and a microring resonator. The through port and drop port of an add-drop microring resonator are connected with the two ports of a tunable reflector. By controlling the thermal phase shifters in different scenarios, the device can be reconfigured into a reflective-type asymmetric Mach-Zehnder interferometer filter, a reflective-type all-pass microring resonator filter and self-interference microring resonator filters. An analytical model is established based on the transfer matrix. The simulation results show that the device can achieve the following functions: sinusoidal spectral filtering with four different free spectral ranges, Lorentzian spectral filtering toggling between band pass and band stop, and spectral reconfigurations of Fano resonance, electromagnetically induced transparency, and electromagnetically induced absorption. Each spectrum mentioned above can be tuned fast and widely. Reflection provides a new degree of freedom in design, breaks through the inherent footprint limit, and achieves a wide range of free spectral ranges. Our proposed tunable Sagnac loop reflector assisted microring resonator provides a new scheme for realizing flexible, tunable and multi-functional reconfigurable integrated photonic filters, and has broad applications in the integrated photonic analog signal processing and microwave photonics.
Playing Software
Authors: Sicart Miguel
Published: February 2023

The play element at the heart of our interactions with computers—and how it drives the best and the worst manifestations of the information age.

Whether we interact with video games or spreadsheets or social media, playing with software shapes every facet of our lives. In Playing Software, Miguel Sicart delves into why we play with computers, how that play shapes culture and society, and the threat posed by malefactors using play to weaponize everything from conspiracy theories to extractive capitalism. Starting from the controversial idea that software is an essential agent in the information age, Sicart considers our culture in general—and our way of thinking about and creating digital technology in particular—as a consequence of interacting with software's agency through play.

As Sicart shows, playing shapes software agency. In turn, software shapes our agency as we adapt and relate to it through play. That play drives the creation of new cultural, social, and political forms. Sicart also reveals the role of make-believe in driving our playful engagement with the digital sphere. From there, he discusses the cybernetic theory of digital play and what we can learn from combining it with the idea that playfulness can mean pleasurable interaction with human and nonhuman agents inside the boundaries of a computational system. Finally, he critiques the instrumentalization of play as a tool wielded by platform capitalism.
Memory
Authors: Craik Fergus , Jacoby Larry
Published: February 2023

A short, accessible primer on human memory, its workings, feats, and flaws, by two leading psychological researchers.

Why do we vividly recall a traumatic childhood event but forget where we left our keys five minutes ago? How can a scent take us back fifty years while a colleague's name eludes us? In this compact introduction, two leading psychological researchers describe memory—how it works and why it sometimes doesn't; how it can be tricked, trained, or improved; and what changes with time.

In a manner as engaging as it is informative, Fergus Craik and Larry Jacoby explain the strengths and weaknesses of memory. They trace evolving ideas about memory's function and present a down-to-earth account of modern views. Citing the latest research, they outline the processes for acquiring and retrieving memories and explore the distinction between conscious and unconscious processes. With insights into the workings of the brain, Craik and Jacoby also provide a succinct account of feats and failures of memory, emotion and false memories, and the effects of aging. Their book draws a clear picture, at once broad and concise, of current and classical views of memory, that most essential and often mysterious feature of human life.
White Sight
Authors: Mirzoeff Nicholas
Published: February 2023

From the author of How to See the World comes a new history of white supremacist ways of seeing—and a strategy for dismantling them.

White supremacy is not only perpetuated by laws and police but also by visual culture and distinctive ways of seeing. Nicholas Mirzoeff argues that this form of “white sight” has a history. By understanding that white sight was not always common practice, we can devise better ways to dismantle it. Spanning centuries across this wide-ranging text, Mirzoeff connects Renaissance innovations—from the invention of perspective and the erection of Apollo statues as monuments to (white) beauty and power to the rise of racial capitalism dependent on slave labor—with ever-expanding surveillance technologies to show that white sight creates an oppressively racializing world, in which subjects who do not appear as white are under constant threat of violence.

Analyzing recent events like the Black Lives Matter protests following the murder of George Floyd and the Central Park birdwatching incident, Mirzoeff suggests that we are experiencing a general crisis of white supremacy that presents both opportunities for and threats to social justice. If we do not seize this moment to dismantle white sight, then white supremacy might surge back stronger than ever. To that end, he highlights activist interventions to strike the power of the white heteropatriarchal gaze. White Sight is a vital handbook and call to action for anyone who refuses to live under white-dominated systems and is determined to find a just way to see the world.
Invention and Innovation

"Every Smil book that I own is marked up with lots of notes that I take while reading. Invention and Innovation is no exception. Even when I disagree with him, I learn a lot from him...he always strengthens my thinking."

—Bill Gates, Gates Notes

The world is never finished catching up with Vaclav Smil. In his latest and perhaps most readable book, Invention and Innovation, the prolific author—a favorite of Bill Gates—pens an insightful and fact-filled jaunt through the history of human invention. Impatient with the hype that so often accompanies innovation, Smil offers in this book a clear-eyed corrective to the overpromises that accompany everything from new cures for diseases to AI. He reminds us that even after we go quite far along the invention-development-application trajectory, we may never get anything real to deploy. Or worse, even after we have succeeded by introducing an invention, its future may be marked by underperformance, disappointment, demise, or outright harm.

Drawing on his vast breadth of scientific and historical knowledge, Smil explains the difference between invention and innovation, and looks not only at inventions that failed to dominate as promised (such as the airship, nuclear fission, and supersonic flight), but also at those that turned disastrous (leaded gasoline, DDT, and chlorofluorocarbons). And finally, most importantly, he offers a “wish list” of inventions that we most urgently need to confront the staggering challenges of the twenty-first century.

Filled with engaging examples and pragmatic approaches, this book is a sobering account of the folly that so often attends human ingenuity—and how we can, and must, better align our expectations with reality.
Implications of altered sirtuins in metabolic regulation and oral cancer
Authors: Quan Xu , Xin Ying , Wang He-Ling , Sun Yingjie , Chen Chanchan , Zhang Jiangying
Published: February 2023

Sirtuins (SIRTs 1-7) are a group of histone deacetylase enzymes with a wide range of enzyme activities that target a range of cellular proteins in the nucleus, cytoplasm, and mitochondria for posttranslational modifications by acetylation (SIRT1, 2, 3, and 5) or ADP ribosylation (SIRT4, 6, and 7). A variety of cellular functions, including mitochondrial functions and functions in energy homeostasis, metabolism, cancer, longevity and ageing, are regulated by sirtuins. Compromised sirtuin functions and/or alterations in the expression levels of sirtuins may lead to several pathological conditions and contribute significantly to alterations in metabolic phenotypes as well as oral carcinogenesis. Here, we describe the basic characteristics of seven mammalian sirtuins. This review also emphasizes the key molecular mechanisms of sirtuins in metabolic regulation and discusses the possible relationships of sirtuins with oral cancers. This review will provide novel insight into new therapeutic approaches targeting sirtuins that may potentially lead to effective strategies for combating oral malignancies.
