Institute for Mathematical Physics on the Cosmology of Type Iia Compactifications on Su(3)–structure Manifolds on the Cosmology of Type Iia Compactifications on Su(3)-structure Manifolds

We study cosmological properties of type IIA compactifications on orientifolds of SU(3)-structure manifolds with non-vanishing geometric flux. These compactifications give rise to effective 4D N = 1 supergravity theories that do not fall under some recently-proven no-go theorems against de Sitter vacua and slow-roll inflation. Focusing on a well-understood class of models based on coset spaces, however, we can use a refined no-go theorem that rules out de Sitter vacua and slow-roll inflation in all but one case. The refined no-go theorem uses the dilaton and a specific linear combination of the Kähler moduli, which is different from the overall volume modulus. It puts a lower bound on the first slow-roll parameter: ǫ ≥ 2. The only case not ruled out is the manifold SU(2)×SU(2), for which we indeed find critical points with ǫ numerically zero. However, all the points we could find have a tachyon corresponding to an eta-parameter η −2.4.
Compost utilization for erosion control

Composting is the controlled biological process of decomposition and recycling of organic material into a humus rich soil amendment known as compost. Mixed organic materials (Example: manure, yard trimmings, food waste, biosolids) must go through a controlled heat process before they can be used as high quality, biologically stable and mature compost (otherwise it is just mulch, manure or byproduct). Compost has a variety of uses and is known to improve soil quality and productivity as well as prevent and control erosion.
Discovery of Cretaceous Mammalia

I T has long been a reproach to paleontology that 110 remains of mammals were known from the Oretaceous formation, which almost everywhere contains abundant evidence of other vertebrate life.

! How knowledge sharing and information availability affect public employees’ job satisfaction

Purpose This research examines the impact of job-related knowledge sharing on information availability and job satisfaction for information-receiving employees in the public sector. Following self-determination theory, the study suggests that job satisfaction is only partly affected by knowledge sharing itself, but particularly through the availability of job-related information enabling the information receiver to work effectively.
Agrarian legacies and innovations in the Nabataean territory

The Nabataeans, a nomadic people inhabiting the southern Near East from the end of the 4th century BC, are mainly known for their trade activities along the Incense Road. Recent scientific advances have shown the importance of agro-pastoral activities within the Nabataean kingdom. However, few studies have addressed the identification of the existing agrosystems and the kinds of associated plant production. This paper focuses on agrarian plant resources exploited in the Nabataean territory by analysing the carpological and anthracological data from four sites (Bosra, Dharih, Petra, Hegra) presented Nabataean and Roman layers dated between the 2nd century BC and the end of the 3rd century AD. The results obtained show the existence of farming systems combining annual and perennial crops, responding efficiently to different economic needs (including food, technical raw materials and fuel). Fruit trees were important and their distribution mainly correlated with climate and topographic constraints. Semi-arid sites developed Mediterranean agroforestry systems while the only arid area site developed an oasis agrosystem. Crop production was directly inherited from preceding periods while the presence of cotton in the Hegra oasis reflects innovative agricultural and technical processes probably related to Nabataean trade activities.
CAR-T Therapy, Where Do We Stand Now?

Chimeric antigen receptor-T (CAR-T) therapy targeting CD19, has revolutionized the treatment of advanced acute lymphoblastic leukemia (ALL) and diffuse large B cell lymphoma (DLBCL). The ability to specifically target the cancer cells has shown high positive results as reported in the registration studies. The success of CAR-T therapy in the first two indications led to the initiation of a large number of studies testing CAR-T therapy in different hematologic tumors such as acute myelogenous leukemia (AML), Hodgkin’s disease (HD), chronic lymphocytic leukemia (CLL), multiple myeloma (MM), as well as different solid tumors. Unfortunately, relapses occurred in the patients treated with CAR-T therapy calling for the development of effective subsequent therapies. Likewise, this novel mechanism of action was also accompanied by a different toxicity profile such as cytokine release syndrome (CRS). Patients’ access to the treatment is still limited by its cost. Another big hurdle is the lack of positive results in different solid tumors. Notwithstanding, this did not prohibit further development of this new therapy and continuing the research activity in solid tumors. This review of research activity of CAR-T will provide an overview on the clinical development of CAR-T in different tumors.
AN EARLY PALEOCENE PALAEANODONT (MAMMALIA, ?PHOLIDOTA) FROM NEW MEXICO, AND THE ORIGIN OF PALAEANODONTA

Abstract We describe a skeleton from the late early Paleocene (Torrejonian) of the San Juan Basin, New Mexico, which represents the oldest and most primitive known member of the Palaeanodonta. It is here named Escavadodon zygus, gen. et sp. nov., and is assigned to the new family Escavadodontidae. The specimen is one of the most complete skeletons of a small mammal known from the San Juan Basin Paleocene. The skeleton combines fossorial postcranial adaptations closely similar to, but somewhat less specialized than, those of early Eocene palaeanodonts, with teeth reminiscent of those of Leptictidae and to a lesser extent Pantolestidae. It thus appears to be morphologically intermediate between Leptictidae and Palaeanodonta, suggesting that Palaeanodonta evolved from Leptictidae or a leptictid-like mammal, and pushing back the origin of Palaeanodonta to at least early Paleocene time.
Context-based coherent surface completion

We introduce an algorithm to synthesize missing geometry for a given triangle mesh that has “holes. ” Similarly to previous work, the algorithm is context based in that it fills the hole by synthesizing geometry that is similar to the remainder of the input mesh. Our algorithm goes further to impose a coherence objective. A synthesis is coherent if every local neighborhood of the filled hole is similar to some local neighborhood of the input mesh. This requirement avoids undesired features such as can occur in context-based completion. We demonstrate the algorithm's ability to fill holes that were difficult or impossible to fill in a compelling manner by earlier approaches.
Optimal Information Disclosure Luis Rayo

A Sender(Internet advertising platform, rating agency, or school) randomly draws a prospect (Internet ad, bond, or student) from a probability distribution. Each prospect is characterized by its pro tability to the Sender and its relevance to a Receiver(Internet user, investor, or employer). The Sender privately observes the pro tability and relevance of the prospect, whereas the Receiver observes only a signal provided by the Sender. The Receiver accepts a given prospect only if his Bayesian inference about its relevance exceeds a private opportunity cost that is uniformly drawn from [0,1]. We characterize the Senders optimal information disclosure rule assuming commitment power on her behalf. While the Receivers welfare is maximized by full disclosure, the Senders pro ts are typically maximized by partial disclosure, in which the Receiver is induced to accept less relevant but more pro table prospects (switches) by pooling them with more relevant but less pro table ones (baits). Extensions of the model include maximizing a weighted sum of Sender pro ts and Receiver welfare, and allowing the Sender to subsidize or tax the Receiver. Acknowledgements to be added.
In Plant Ecology, Evolution and Systematics Predicting Global Change Impacts on Plant Species' Distributions: Future Challenges

Given the rate of projected environmental change for the 21st century, urgent adaptation and mitigation measures are required to slow down the ongoing erosion of biodiversity. Even though increasing evidence shows that recent human-induced environmental changes have already triggered species' range shifts, changes in phenology and species' extinctions, accurate projections of species' responses to future environmental changes are more difficult to ascertain. This is problematic, since there is a growing awareness of the need to adopt proactive conservation planning measures using forecasts of species' responses to future environmental changes. There is a substantial body of literature describing and assessing the impacts of various scenarios of climate and land-use change on species' distributions. Model predictions include a wide range of assumptions and limitations that are widely acknowledged but compromise their use for developing reliable adaptation and mitigation strategies for biodiversity. Indeed, amongst the most used models, few, if any, explicitly deal with migration processes, the dynamics of population at the ''trailing edge'' of shifting populations, species' interactions and the interaction between the effects of climate and land-use. In this review, we propose two main avenues to progress the understanding and prediction of the different processes occurring on the leading and trailing edge of the species' distribution in response to any global change phenomena. Deliberately focusing on plant species, we first explore the different ways to incorporate species' migration in the existing modelling approaches, given data and knowledge limitations and the dual effects of climate and land-use factors. Secondly, we explore the mechanisms and processes happening at the trailing edge of a shifting species' distribution and how to implement them into a modelling approach. We finally conclude this review with clear guidelines on how such modelling improvements will benefit conservation strategies in a changing world.
Cellular and Molecular Biology

: Y chromosome has a number of genes that are expressed in testis and have a role in spermatogenesis. TTY2L12A and TTY2L2A are the members of testis transcript Y2 (TTY2) that are Y linked multi-copy gene families, located on Yp11 and Yq11 loci respectively. The aim of this study was to investigate frequency of TTY2L12A and TTY2L2A deletions in azoospermic patients compared with fertile males. This study was performed on 45 infertile males with idiopathic azoospermia without any AZF micro deletions (group A), 33 infertile males with azoospermia which do not screened for AZF micro deletions (group B) and 65 fertile males (group C), from October 2013 to April 2015 in west of Iran. Polymerase chain reaction (PCR) method was used for detection of TTY2L12A and TTY2L2A gene deletions in studied groups. No deletions were detected in normal fertile males of group C. 1 out of 45 azoospermic males of group A (2.22%) and 3 out of 33 azoospermic males of group B (9.09%) had TTY2L2A deletion (p= 0.409 and p= 0.036 respectively), also 1 out of 45 azoospermic males of group A (2.22%) and 4 out of 33 azoospermic males of group B (12.12%) had TTY2L12A deletion (p= 0.409 and p= 0.011 respectively). None of azoospermic males in Group A and B had deletions in both genes. Our data showed significant correlation between non-obstructive azoospermia and TTY2L12A and TTY2L2A dele - tions. Thus, it seems that TTY2L12A and TTY2L2A deletions can consider as one of the genetic risk factors for non-obstructive azoospermia.
Magnetic Resonance Diffusion

Background: The cerebellopontine angle (CPA) is a triangular subarachnoid space located within the posterior cranial fossa and centered at the level of the internal audiotary canal. Approximately 10%of intracranial tumors arise in the cerebellopontine angle and 80% of these are vestibular schwannomas. The majority of the remaining 20%are meningiomas, with rare incidance of facial or trigeminal schwannomas, epidermoid cysts(primarycholeseatomas), glomus jugular tumors, arachnoid cysts, giant cell tumors, metastatic deposits, and other masses. Objective: To evaluate the role of DWI, susceptibility and specrtroscopy in evaluation of cerebello pontine angle masses. Patients and methods: Our study included thirty cases with CPA masses that were subjected to advanced MRI techniques (DWI, SWi and, MRS) in addition to the conventional MRI techniques to evaluate their role in evaluation of CPA masses. Results: By using DWI in our protocol, we proved that; It can differentiate shwannomas, meningiomas and epidermoid cyst; where meningiomas are always restricted with low ADC values (mean ADC value < 1× 10−3 mm2 /s) while shwannomas have higher ADC values (mean ADC value >1× 10−3 mm2 /s) and epidermoid cysts are restricted with ADC values <1× 10−3 mm2 /s. By using SWI: SWI also proved to has an important value in differentiating meningiomas and shwannomas where in our study no meningiomas showed blooming on SWI while 61.5 % of shwannomas showed blooming (likely due to intra-lesional hemorrhage). Thus the presence of blooming within a lesion (after exclusion of calcifications) would rather the diagnosis of shwannoma than meningioma. By using MRS: 100% of shwannomas showed myo-inositol peak in our study and 87.5% of meningiomas showed alanine peak and 100% of meningiomas showed glutamate\glutamine peak, proving that MRS can be an accurate technique in differentiating the two entities. 100% of metastatic lesions showed choline peak in our study so MRS has an important value in the diagnosis of metastatic lesions. Conclusion: Advanced MRI techniques as DWI, susceptibility and spectroscopy have a great value in evaluation of CPA masses.
Performance evaluation of a singular subsurface tile draiange system of Swabi SCARP.

A well maintained subsurface tile drainage system plays an important role in the reclamation of waterlogged and saline area as well as improves crop productivity. A field study was conducted to evaluate the performance of subsurface tile drainage system during the years 1998 and 2011 in terms of depth to water table from the ground surface, drainage coefficient hydraulic conductivity and yield of major crops. The system was installed under Swabi Salinity Control and Reclamation Project (SCARP) in July, 1997 in the North-West of Pakistan. The study area is being drained by nine subsurface tile drains spaced 100 to 150 m and length ranged from 500 to 700 m at design depth of 1.5 m from the ground surface. Depth to water table and discharge of tile drains were measured on a weekly basis, while yields of major crops were recorded at harvest stage. Average depth to water table from ground surface ranged from 1.0 to 1.6 m and 0.8 to 1.2 m during the study periods 1998 and 2011 respectively. The water table was slightly (8%) higher in 2011 as compared with 1998 due to blockage of half of the laterals. Sugarcane and rice crops were not affected by the re-emerging water logging during 2011 due to blockage of tile drains while on the other hand wheat and maize were found sensitive to water logging as there yields were 42 and 9% lower under shallower water table condition. The overall mean drainage coefficient of 1998 was 1.65 mm day, while in 2011 it decreased to 0.7 and 1.3 mm day in partially blocked and unblocked tile drains command area due to blockage of some of the tile drains. An average hydraulic conductivity before the project (1995) was 0.79 m day and it increased to 1.31 m day in 1998 and showed a further increase to 1.71 m day in 2011. It can be concluded that the major goals of the installation of singular subsurface pipe drainage system have been achieved during the early years after completion of the project as the project was successful in lowering the water table and increasing crop yield but the long term performance was adversely affected by improper maintenance of the main drain, subsurface tile drains and plantation of poplar (Poplus nigra) trees across the laterals.
Zircon Chronology of Melanocratic Dykes in the District of the Xiaoxinancha Au-Rich Cu Deposit in Yanbian and Its Geological Implication

Zircon SHRIMP and LA-ICP-MS U-Pb dating was performed on diabase gabbro of premineralization stage and dioritic porphyrite dykes of mineralization stage,collected from the Xiaoxinancha Au-and Cu-rich deposit,both of which have closely relation in spatial distribution.The results show that five sets of concordant ages for 16 zircon grains or spots from diabase-gabbro are obtained,i.e.387.0±11.8Ma,292.0~251.1Ma(Mean=270 ±14Ma,n=10),129.8±2.6 Ma,107.0-95.6Ma(Mean=103±13Ma,n=3)and 46.8±2.6Ma;whereas one set of concordant ages ranging from 108-98Ma(Mean=102.1±2.2Ma,)for 11 zircon grains and 12 spots from diorite porphyrite are obtained.Combined with the features of CL images,it was suggested that the premineralization diabase-gabbro was formed in the late Early Permian epoch and trapped some detrital zircons during magma ascending(intruding)and subsequently experienced thermal modifications in the early Cretaceous and middle Eocene time.Diorite porphyrite was formed in the late Early Cretaceous.Considering the match of the age of diorite porphyrite with age 107.0-95.4Ma of the diabase gabbro,the ages of hydrothermal zircons from the diabase gabbro range between 103~95.4Ma,which further indicates that thermal event of the gold-copper mineralization took place in 108-98Ma and the mineralization occurred during the late stage of middle/late Mesozoic when the crust experienced intensive extension and thinning.Then,the gold-and copper-rich deposit was exposed to the present surface due to uplifting and denudation processes during the late Cretaceous Paleocene period.In general,the mineralization was 10Ma behind the large-scale magmatic-hydrothermal gold mineralization(120Ma)in East China during the late Mesozoic.
Performance Comparison of OFDM and DFT-s-OFDM in the THz-Band Communications Channels

The terahertz (THz) band is a promising frequency band that ranges from 0.3 THz to 10 THz and being considered for the next generation 6G wireless networks due to the large available bandwidth and potentially ultra fast data rates. THz channels and systems are unique in three aspects: 1) high path loss; 2) rich scattering from rough surfaces; 3) severe phase noise from local oscillators. These pose questions on what physical waveforms should be used in THz channels. Since orthogonal frequency division multiplexing (OFDM) and discrete Fourier transform spread OFDM (DFT-s-OFDM) are adopted waveforms in 5G new radio (NR) and 4G, their possible use in the future generation wireless networks is an open question. In this paper, we first review a THz channel model for accurate representation of THz channels. Then uncoded and coded OFDM and DFT-s-OFDM systems are investigated for their performance in THz channels, demonstrating their unique behaviors in these channels. The impact of phase noise is also examined, and a non-iterative compensation method slightly modified from the literature is used to mitigate the phase noise effect. DFT-s-OFDM shows advantages over OFDM in the studied THz environment. The simulation results in this paper can be used as a benchmark for future studies.
Harnessing Disarmed Criticism to Reinforce Neoliberal Capitalism: The Case of Justification Work in Social Business

This article analyses how dominant discourse reinforces neoliberal capitalism. While most critical studies focus on manufacturing consent, we show how dominant discourse both harnesses and disarms criticism to establish change as a mode of complex domination. We investigate how the ‘guruesque’ discourse of social business puts capitalism to the test. Our discourse analysis highlights how three Muhammad Yunus’ books align subject positions, problems, objectives, and solutions to make neoliberal programmes the solutions to societal issues. Taking the theoretical turn in pragmatic sociology, we build on late Boltanski’s work to show how this justification work connects world and reality differently in truth, reality, and existential tests. We make three contributions. First, we revisit how justification work disarms criticism, showing that it is less about reaching moral agreement than about depriving criticism of its voices, targets, imagination, and alternatives. Second, we reconsider the notion of tests, showing that truth, reality, and existential tests combine within a single discourse to equally legitimate the neoliberal reality. Third, we advance knowledge on complex domination,
Room Adaptation of Training Data for Distant Speech Recognition

We present a novel signal processing-based approach for estimating room impulse responses for augmentation of ASR training data that is best suited to the reverberation characteristics in a particular acoustic space. Our approach estimates an impulse response of a room by using a supervised adaptive system identification algorithm to extract the relative transfer function between a speech source played through a loudspeaker and recorded by a microphone. These impulse responses can then be applied to clean speech files to create an augmented training set for an ASR system. Given the availability of a small amount of this type of playback audio for a room, we show that an ASR model trained with our data augmentation approach can provide a 19% relative reduction in word error rate compared to a system using random augmentation.
Improving Inertial-Based UAV Localization using Data-Efficient Deep Reinforcement Learning

Precise localization is a critical task for many Unmanned Aerial Vehicle (UAV)-based applications. Inertial-based navigation, which relies on Inertial Measurement Units (IMUs), is extensively used to this end, due to its low-cost and small footprint. However, IMU-based localization leads to accumulating significant localization errors. To overcome this limitation, in this paper we propose a data-efficient Deep Reinforcement Learning (DRL) method that enables learning how to correct localization errors from IMUs leading to more precise localization. In contrast with supervised approaches, the proposed method employs a novel data augmentation and regularization approach, which requires collecting a minimal number of real examples, while it is also platform-agnostic and can account for manufacturing impressions. The effectiveness of the proposed method is demonstrated both in a simulation environment, as well as using a real UAV.
