Abstract:
This is part 135 of a chronology begun by the Journal of Palestine Studies in Spring 1984, and covers events from 16 May to 15 August 2017 on the ground in the occupied Palestinian territories and in the diplomatic sphere, regionally and internationally. U.S. pres. Donald Trump continued work on a largely undefined peace initiative without much progress. Violence in the Old City of Jerusalem interrupted U.S. efforts, and the Israeli government imposed new security restrictions at Haram al-Sharif, sparking a wave of unrest across the occupied Palestinian territories and a Muslim boycott of the sanctuary that put the nascent U.S. initiative to the test. Palestinian Authority president Mahmoud Abbas increased pressure on Hamas to relinquish control of Gaza to the PA. The 1,500-plus Palestinian prisoners who declared a mass hunger strike last quarter secured key concessions from the Israeli authorities and brought their “Dignity Strike” to a close. Saudi Arabia, Egypt, Bahrain, and the United Arab Emirates enacted a diplomatic and economic boycott of Qatar.

Abstract:
Progress in radiocarbon dating and calibration accuracy should lead to the development of a calibrated radiocarbon chronology of Near Eastern archaeology, particulary for historical times. The lack of such an independent and impartial chronology is a major constraint, not only in archaeological studies, but also for interdisciplinary research involving the history of man, landscape and climate in the Near East and adjacent regions.

Abstract:
The purpose of this treatise is to provide an educational text that (a) cites existing literature supporting a mind-body paradigm for rehabilitation from psychophysiological and psychomotor perspectives, (b) demonstrates the application of imagery techniques within the chronology of an athletic injury, and (c) describes the performance-related criteria to which an athlete can compare his or her progress during rehabilitation. The chronology includes the period of time preceding the injury, the attention given to the athlete immediately following the injury, and the subsequent rehabilitation program leading to the athlete’s return to practice and competition. Examples of imagery experientials are used to illustrate its application throughout the chronology.

A fundamental aspect of ancient Egyptian history remains unresolved: chronology. Egyptologists (and researchers in related fields that synchronize their studies with Egypt) currently rely on a variety of insufficiently precise methodologies (king lists, radiocarbon dating, etc.) from which to derive seemingly “absolute” dates. The need for genuine precision has been recognized for a century, as has the potential solution: dendrochronology. This manuscript presents a case for further progress toward the construction of a tree-ring chronology for ancient Egypt.

Abstract:
The origin of pottery is among the most important questions in Old World archaeology. The author undertakes a critical review of radiocarbon dates associated with the earliest pottery-making and eliminates a number of them where the material or its context are unreliable. Using those that survive this process of ‘chronometric hygiene’, he proposes that food-containers made of burnt clay originated in East Asia in the Late Glacial, c. 13 700-13 300 BP, and appeared in three separate regions, in Japan, China and far eastern Russia, at about the same time.

Full text
Abstract:
We describe methods and progress in developing the American Long Oak Chronology (ALOC), an effort to construct an oak tree-ring chronology from the Central US that spans the Holocene. Since 2000, we have collected and measured ring widths on over 550 pieces of subfossil oak (Quercus) wood. Over 330 oak samples have been radiocarbon dated, with ages ranging up to 14,000 cal yr B.P. A 1,093- year-long tree-ring record has been constructed from live and subfossil bur oaks (Q. macrocarpa Michx.) and swamp white oaks (Q. bicolor Willd.) growing along and buried in sediments of streams that flow through northern Missouri and southern Iowa, USA. Here we describe the ALOC for the period A.D. 912–2004 to demonstrate its dendrochronological value, display the material quality, and emphasize the importance of chronology construction. We also report on progress in developing older floating chronologies. The development of more long, multi-millennium chronologies will be an important contribution to dendroclimatology. These chronologies will be particularly useful to the Central US, a region with a continental climate and limited temporal depth of annually resolved paleorecords. Perhaps more critical is its location in the middle of one of the most important agricultural regions in the world.

Abstract:
Well replicated tree-ring samples were collected, dated and measured for California west of the Sierra Nevada, eastern Oregon and the northern Great Basin. A computer program was developed and used to check crossdating quality. Another computer program to generate and analyze tree-ring chronologies was evaluated, further developed cooperatively and used to produce chronologies for the dated site collections. This report contains these site chronologies in three versions along with site descriptions and chronology statistics. Users manuals are included for the two computer programs. The effect on a chronology of poor crossdating is discussed, and a study of standardization of tree-ring measurement series is reported. Some new techniques are described for processing tree-ring samples.

Abstract:
This chapter continues the discussion of critique’s of Isaac Newton’s The Chronology of Ancient Kingdoms. Among these was by Arthur Bedford, whose main objection to Newton’s work, even more than its violation of the scriptural account of the peopling of the earth, was Newton’s pinpointing the beginnings of Greek idolatry in King David’s time, with Ceres allegedly the first to be worshipped as a deity. In so doing, Bedford charged, Newton ignored the extensive evidence furnished by Scripture regarding the pervasiveness of idolatry ever since Nimrod’s day. Here Bedford resorted to distortion, for Newton explicitly stated that “Idolatry began in Chaldaea and Egypt, and spread thence into Phoenicia and the neighboring countries, long before it came into Europe.” Unfazed, Bedford enumerated at great length the rise and progress of idolatry according to Scripture, before damning Newton who, “without the least Shadow of Proof, contradicts all at once, and brings both the Scripture History and Chronology into the outmost Confusion.”

Abstract:
Abstract Jn 1842, on the death of Thomas Coke, the second earl of Leicester, his tenants erected a monument to celebrate his encouragement of agricultural ‘improvement’. A column was surmounted by a sheaf of wheat and flanked by a massive cow, plump sheep, and modem plough; the frieze around the base showed Coke passing on his advice to a prosperous and grateful tenantry. The monument symbolizes one view of the process and chronology of agricultural growth: a ‘modernizing’ landowner swept away ignorance, breaking the shackles of tradition, and allowing yields and output to rise at the close of the eighteenth century. But should the monument be read instead as an exercise in deference and self-justification? The analysis of Malthus and Ricardo would suggest a different interpretation: by the end of the eighteenth century, growth of output could only be achieved at the expense of decreasing marginal returns, and prices and rents rose as population growth outstripped the capacity of the land to provide food. Perhaps the monument, on the hill above Coke’s lavish Palladian house, symbolized Ricardian rent rather than an agricultural revol¬ ution, marking the increased power and wealth of great landowners at the expense both of consumers who paid more for their food and of farmers who paid more for the use ofland.

This chapter updates the reader on the two decades of research into Viking-Age combs that have taken place since the publication of Vikings in Scotland. As well as the publication of several new excavation assemblages, particularly from the Northern Isles, progress has also been made in the study of existing collections. New, biomolecular approaches, such as aDNA and zooarchaeology by Mass spectrometry (ZooMS) can distinguish diverse animal tissues, such as reindeer vs red deer antler from specific combs and excavation assemblages. This has led to a greater understanding of the chronology and character of early Viking-Age Scotland, maritime activity, and the dynamics of the diaspora and trade in the North Sea, Irish Sea and North Atlantic.

Abstract:
The intersection of computer vision and natural language processing (NLP) has witnessed significant advancements in recent research, particularly in the realm of converting text into meaningful images leveraging generative AI and large language models. This review work aims to comprehensively review the progress made in text-to-image conversion. The survey covers the three primary approaches in the field, namely diffusion models (DM), GAN model approaches, and autoregressive approaches. Furthermore, the authors present a comprehensive chronology of the TIG journey, encompassing its origin and the most recent developments, providing readers with a comprehensive perspective on the field's progression. The survey focuses heavily on identifying the existing constraints of DM in picture production and offers multiple research publications and their contributions in overcoming these constraints. The survey provides useful insights into the advancements in text-to-image (TIG) generation using generative AI by focusing on key difficulties and examining how different works have addressed them.

Abstract “In partibus” takes Bianchini to France in 1713 while terms for ending the War of the Spanish Succession were under discussion at Utrecht. The ostensible purpose of his journey was to bring a cardinal’s hat to the newly appointed Cardinal de Rohan; but he had with him at least two ciphers for communicating in code the progress of business he had undertaken for the Ottobonis and the Pope. He made many friends in high places, most significantly James III, the claimant to the British thrones, whose cause he took up almost as his own. After finishing his work in Paris, Bianchini toured the lands of the heretics; after Holland, England, where he met Newton and assessed James’s chances of inheriting Britain from his half-sister Queen Anne despite his being a Catholic excluded from the succession by act of Parliament. Bianchini got along very well with English scholars he was obliged to regard as heretics, especially Newton, with whom he shared a deep interest in ancient chronology.

There is a constant need for newer exceptional materials with better than ever properties to achieve new prerequisites of the future society and progress inventive industrial improvement. The potential to combine these oxides in composite structures to produce multifunctional materials has rekindled interest in perovskites (ABO3) compounds over the past 10 years. Because of its intriguing characteristics, such as ferroelectricity, piezoelectricity, superconductivity, multiferroicity, photocatalysis, enormous magnetoresistance, dielectric, ionic conduction characteristics, etc., a huge variety of perovskite types have been thoroughly explored. Current applications for perovskite solids include electronics, geophysics, astronomy, nuclear, optics, medicine, the environment, etc. Perovskite compounds have distinctive features that make them suitable for a variety of commercial and technological applications, including capacitors, non-volatile memories, photo-electrochemical cells, catalysts in contemporary chemistry, actuators and sensors, ultrasonic and underwater devices, drug delivery, spintronics devices, tunable microwave devices, and many others. Potential applications for nanoscale perovskites include energy storage, fuel cells, nanomedicine, molecular computing, nanophotonics adjustable resonant devices, catalysts, and sensors. Nanoscale perovskites have intriguing features that are comparable to or better than those of bulk perovskites. This review includes topics such as perovskite structured materials’ chronology, classification, production, crystal structure, special physical properties, and applications.

Abstract:
Abstract Chronolog is a logic programming language based on temporal logic and possible worlds semantics. Temporal logic allows us to describe dynamic and time-dependent properties of certain problems in a direct and problem-oriented way. In Chronolog programs, users specify time-varying predicates; thus the notion of dynamic change and dataflow-style of non-terminating computations can be naturally specified in Chronolog. The declarative semantics of Chronolog programs can be characterized in terms of the least model semantics; hence Chronolog does not have some of the problems associated with non-logical extensions of logic programming. Chronolog extended with choice predicates (arbitrary single-valued relations) is suitable for modelling mutual exclusion problems such as that of the dining philosophers. A natural extension of Chronolog with modules allows us to specify objects with internal memory.

Full text
Abstract:
Contemporary perception of time differs significantly from historical one. The contemporary time is speeding, divergent, meticulously quantified with abstract units, disconnected from perception of space. Differences between day and night, physical and digital, far and near are constantly, gradually vanishing. With this new time perception, contemporary urban space has evolved. Cities extend, their centres melt; deallocation, speed and light images explode interior-exterior oppositions. The space aspires to the speed of light. Shizophrenic, kinetic reality, where signifiant leaves signifié is characterized by discrepancies: economic barriers, fences, and incessant opening into virtual reality. Time is a factor joining events in narration and in architecture. Chronology of events is shattered in contemporary literature, introducing strategies of retrospection, anticipation and anachrony. The situation in contemporary architecture is similar. These strategies appear also in contemporary cities: retrospection in historic monuments, anticipation in avant-garde, “science-fiction” buildings and anachrony in non-places on the verge of physical and virtual reality. Lines of events in a plot of a city’s narration has changed. Certain duality of a contemporary city space appears: perception of sheer time in ruins, monuments, and a temporal flow of events-spaces. Along with the speeding urban organism, an idea of slow city spaces has appeared. The idea of a city “tasted” with senses, replacing the terms of acceleration, progress and change with: slowness, reflection, variety, essence; effects of reflective attitude towards reality, traces of resistance against the inevitable loss of beauty in contemporaneity. A phenomenological approach as a response for the speeding city reality. Thisarticle analyses affiliations between the contemporary perception of time, narrative strategies and city space.

Net evolution of subglacial sediment transport in the Quebec-Labrador Sector of the Laurentide Ice Sheet, Quebec and Newfoundland and Labrador. Natural Resources Canada/CMSS/Information Management, 2023. http://dx.doi.org/10.4095/332151.

Full text
Abstract:
The interior of the Laurentide Ice Sheet (LIS) had a dynamic polythermal base. However, the subglacial thermal organization of the LIS and its evolution throughout glaciation are poorly constrained. Specifically, the net effect of ice divide migration on subglacial processes and the resulting landforms and sediments remains poorly understood. The results of a regional-scale till sampling program within the interior of the Quebec-Labrador sector of the LIS were used to explore dispersal patterns across a region known to have experienced ice divide migration. Indicator mineral and clast lithology analysis, coupled with multivariate analysis of the till matrix geochemistry, were used collectively, and evaluated within the context of the relative ice flow chronology and subglacial thermal evolution to augment our understanding of how ice divide migration impacts subglacial erosion and sedimentary processes. Indicator minerals (e.g., goethite and orthopyroxene) and clasts (e.g., iron formation clasts from the Labrador Trough) form glacial dispersal patterns that are consistent with the earliest northeast-trending ice-flow phase identified in the region. This early ice-flow phase produced and transported till across the entire study area (> 175 km). However, till matrix geochemistry shows a strong relationship with the local underlying bedrock, especially the major oxides. This relationship is relatively common in areas of thin till cover and resistant bedrock lithologies. The results also indicate that following the northeast ice-flow phase, erosion and till production became more localized, without considerable transport in a single sustained direction. These results are consistent with a transition to more sporadic warm-based conditions and ice divide migration, as ice sheet reconstructions indicate, and are supported by targeted 10Be data from erratics and bedrock surfaces. There are also spatial relationships between the dispersal of fresh or re-entrained debris and paleo-ice streams identified in the landform record, as evidenced by the dispersal of indicator minerals. The reworking of previously dispersed material during subsequent ice-flow phases resulted in complex dispersal patterns across the study area. These results provide important insights for ice sheet modelling and future mineral exploration programs in inner ice sheet regions of the LIS and demonstrate the importance of a thorough understanding of ice-flow history.
